Preface
1 Introduction This chapter provides an overview of Replication Manager features and architecture. It also provides an introduction to supported system configurations and an operations roadmap. About Replication Manager Replication Manager is a business continuity management framework that allows you to centrally configure, monitor, and manage in-system or remote business continuity products, for both mainframe and open environments.
Replication Manager features Replication Manager provides the following features to assist storage administrators: • • • • • Centralized management of a replication environment Integrated database backup management Visual representation of replication structures Monitoring and immediate notification of error information Modification of replication structures NOTE: If Replication Manager is installed without a license (or the existing license expires), only basic pair configuration functions will be availa
Modification of replication structures Replication Manager provides capabilities to configure additional copy pairs as business operations expand and improve performance by expanding buffer capacity for copying volumes. You can also change pair states manually after error recovery. Using the wizards provided in the GUI, you can set up pairs while visually keeping track of complex replication structures.
manage the hosts by registering the instance of HP StorageWorks P9000 for Business Continuity Manager Software or P9000 mainframe agent installed on each host in the local and remote sites as an information source. • Database and backup servers: To manage database replicas, the system requires two servers: a database server that manages the primary volume, and a backup server with the secondary volume.

Figure 4 Example system configuration managing copy pairs and application replicas Replication Manager operations roadmap The following figure shows the flow of tasks during system configuration, operation, and maintenance.
TIP: If you want to change the system configuration or the Replication Manager settings during operation, you should back up the database before and after making any changes. For details on system configuration, system maintenance, and database backup, see the HP P9000 Replication Manager Software Configuration Guide.
Introduction
2 Getting started This chapter describes initial settings needed to begin Replication Manager operations and procedures for setting up the prerequisite environment for pair management. It also includes quick references to typical operations performed using Replication Manager. Using the Help system The Replication Manager online help system is context-sensitive; when you click Help from within a window or dialog box in the Web client, information specific to the task you are performing displays.
You can also print information in topics by clicking the Print icon located in the top right of your Help window. Initial setup After Replication Manager has been installed on a management server, you must configure initial settings needed to begin Replication Manager operations. Initial settings configuration workflow The following figure shows the task flow of the initial configuration settings.
WARNING! N:M and 1:M configurations are intended for use in disaster recovery. N:M and 1:M configurations cannot be used to create or restore application replicas.
Figure 5 Example of redundant pair management server configuration Registering redundant pair management server nodes (while creating a copy group) You register the initial primary/secondary pair management servers when creating a new copy group from the Group Management page of the Pair Configuration Wizard: 1. Click Create Group. 2. Enter the Group Name. 3. Select the Site and Server Name for the primary and secondary pair management servers.
Registering redundant pair management servers manually If you are constructing the redundant pair management server configuration manually, be sure and do the following: 1. 2. 3. Use a P9000 RAID Manager command to change the configuration of the copy pair. Set up the HORCM configuration files so that each primary HORCM file has all secondary targets and vice versa.
• Prerequisite products for Replication Manager are installed and their environment settings are configured • Replication Manager is installed on the management server, and an environment is set up • If you plan to create replicas, make sure the Application Agent is installed on the database and backup servers • A Replication Manager license is set up Logging in and out To log in to Replication Manager: 1.
If you are logged in to another P9000 Command View AE Suite product, you can also start Replication Manager using the GO link for RepMgr displayed in the Dashboard menu. If you logged in to Device Manager from HP SIM, you can invoke Replication Manager software from Device Manager. In this case, you can perform the Replication Manager software operations permitted by the permissions of the user account that you used to log in.
Getting started
3 Replication Manager console This chapter describes the Replication Manager console and its main features. This chapter also provides descriptions of various functional views available in the Replication Manager console. Understanding the console layout Replication Manager provides a simple, easy-to-use, centralized management console for monitoring and visualizing volume replication configurations and status information. The following example is an illustration of Replication Manager console layout.
• Restrictions related to the GUI, page 443 Global tasks bar area The global tasks bar area contains menus and action buttons for Replication Manager functions, and also contains information about the logged-in user. A triangle icon is provided to show or hide the Explorer and Dashboard menus. Global tasks bar area menu items Menu Explanation Close Closes the window, but does not log the user out from Replication Manager and other active P9000 Command View AE Suite products.
Explorer menu items Menu item Explanation Displays resources such as application servers or hosts, storage systems, and pair management servers managed by Replication Manager. • Hosts: Displays information about the hosts managed by Replication Manager (hosts view). Resources • Storage Systems: Displays information about the storage systems managed by Replication Manager (Storage Systems view).
Menu item Explanation Tasks: Displays the tasks scheduled for copy pairs. Tasks Workflows: Displays the workflow generated for copy pairs. Alerts Alerts: Allows you to check alerts or edit alert settings. User Profile: Allows you to check or edit user information. Settings License Info: Sets the Replication Manager license information. Refresh Setting: Allows you to update the information managed by Replication Manager and set the interval for updating the information.
Dialog box A dialog box is a pop-up window displayed when an action button is clicked. The window displayed when a specific action button is clicked is called the action-name dialog box. Clicking Help in a dialog box displays the online help page that describes the items displayed in the dialog box. Functional views Replication Manager provides multiple views that display pair configurations and the status of the replication environment from different perspectives.
Structure of the Hosts view The figure below shows the structure of the Hosts view with the list of hosts as the starting point. The subwindow changes according to the hierarchy displayed in this structure.
Storage Systems subwindow The Storage Systems subwindow lets you view storage systems containing paired volumes and the copy licenses registered for each storage system. For details on the meanings of the icons, see “Icons representing the management target” on page 440 or “Display formats used when no pertinent information is available” on page 451.
Displays the types of the storage systems. Storage System Type For mainframe systems, you can identify the type of a storage system only when the storage system is registered in the Device Manager server and that server is registered as an information source. If you cannot identify the type, the storage system family is displayed (from among XP1024/XP128, XP12000/10000/SVS200, and XP24000/ 20000). Displays the copy types for which licenses are registered in open systems or mainframe systems.
Pair configurations subwindow The Pair Configurations subwindow lets you view pair management servers with copy pair definitions (P9000 RAID Manager configuration definition file) and related information. Pair Management Servers Pair Management Server Displays the name of the pair management server that issues instructions to storage systems to perform a copy pair operation.
Information Source Displays the name (nickname) of the Device Manager server, instance of HP StorageWorks P9000 for Business Continuity Manager Software, or instance of P9000 mainframe agent. Structure of the Pair Configurations view The figure below shows the structure of the Pair Configurations view with the list of copy pair configuration definitions as the starting point. The subwindow changes according to the hierarchy displayed in this structure.
TIP: For mainframe pair configurations, the tree structure of the pair configurations appears differently for copy groups within containers and copy groups that are not. • For copy groups not within a container, the copy group nodes are displayed directly under the prefix nodes and the node name of the copy groups is consistent with the dataset names.
Applications Item Description Application Displays Exchange or SQL. Displays the status icon that represents the current state of protection. Data Protection Status See “About data protection status” on page 286 for a list of icons and their meanings. Structure of the Applications view The figure below shows the structure of the Applications view with the list of applications (Exchange or SQL) as the starting point. The subwindow changes according to the hierarchy displayed in this structure.

Replication Manager console
4 Setting up information sources Before you can use Replication Manager to manage resources, you must register an information source. In open systems, this information source is the Device Manager server. In mainframe systems, this information source is either HP StorageWorks P9000 for Business Continuity Manager Software or P9000 mainframe agent.
TIP: If you register Device Manager servers, you can configure links for invoking the instances of registered Device Manager servers from Replication Manager. You can register links to the servers in the Go menu of the global tasks bar area. You can set the link by executing the hcmdslink command on the management server. For details on this command, see the HP P9000 Replication Manager Software Configuration Guide.
Adding a Device Manager server TIP: Only a user who has the Admin permission can add a Device Manager server. To add a Device Manager server: 1. Ensure that you have the following information: 2. • IP address or host name • Protocol to be used for communication with Replication Manager software (HTTP or HTTPS) • Port number (the server.http.port value in the server.
Adding an instance of HP StorageWorks P9000 for Business Continuity Manager Software or P9000 mainframe agent CAUTION: If you have an HP StorageWorks P9000 for Business Continuity Manager Software environment where multiple BCM instances have overlapping copy group or disk configuration definition files, see “When multiple BCM instances have overlapping configuration definition files” on page 57 first.
Once an instance of BCM is registered, Replication Manager loads the configuration information associated with the BCM for the purposes of scanning the volumes as described in “About mainframe volume discovery” on page 67.
Adding an instance of Application Agent To add an instance of Application Agent: 1. Make sure you have the following information concerning the host where Application Agent has been installed: • Name of Application Agent identified by Replication Manager • Host ID. For a physical host (stand-alone), the IP address or host name of production server where the agent is running. (IPv4 and IPv6 addresses are supported.
Related topics • Setting Application Agent options, page 59 • Editing an instance of Application Agent, page 360 • Refreshing Application Agent, page 64 Setting Application Agent options After adding an instance of Application Agent, you must configure the options for the agent before the application discovery process can proceed. The options differ depending on whether the host is a database or backup server.
6. For cluster configurations, the Cluster Options tab is displayed. This tab sets the required Shared Data Path (location of the application configuration information used by Application Agent) and selects the Restore Mode (whether or not to keep cluster resources online).
Settings for virtual hosts and cluster configurations For the settings below, any settings applied to a physical host are automatically applied to all virtual hosts running on the physical host. This applies to cluster configurations as well.
Manual operation When a task has been created through the Pair Configuration Wizard with the Applications view, you can conceal or reveal volumes manually when adding or deleting pair groups. In the Edit Task[s] dialog box, go to the Pair Operation section of the Pair Setting tab. The Reveal Secondary Volumes option is is displayed when an attempt is made to delete a copy pair or group definition, and Conceal Secondary Volumes option is displayed for a creation operation.
Therefore, to execute the verification process in parallel and increase the performance, it is ideal to increase the number of FC ports connecting the server and storage and provide a configuration to enable multiple processing of I/O with respect to the disk.
Parameter Description Notes SG_NUM Number of storage groups to back up per database server (for Exchange Server 2010, use a value of 1) You must supply this value. Because storage groups are not supported in Exchange Server 2010, use a value of 1 in this case. DB_SERVER Number of database servers You must supply this value. SYSTEM_BACKUP_TIME Time allowed for backing up the entire system (seconds) You must supply this value.
• Application Agent component version • Parameters displayed on the setup windows To refresh the Application Agent data: 1. From the Explorer menu, choose Administration and then Information Source. The Information Source subwindow appears. 2. Expand the object tree, and then select Application Agent. The Application Agent subwindow appears. 3. Select the check box each server desired and click Refresh Agent. The confirmation dialog box displayed. 4.
Setting up information sources
5 Discovering volumes Before you can use Replication Manager to define or manage copy pairs, it is necessary to discover volumes. As a result of this discovery process, Replication Manager identifies a list of volumes that can be used for pair definition. This chapter describes how to discover volumes. Discovering volumes (open systems) Open systems volumes are discovered by refreshing configuration information after registering an information source.
1. 2. 3.
Example volume scan procedure Types of volume scans Replication Manager uses one of three available scanning methods to discover mainframe volumes: Local scan (Gen'ed) This method discovers volumes recognized by the mainframe host within a specified DEVN/VOLSER range. Local scan (Non Gen'ed) This method discovers volumes within a specified storage system and LDEV range. As a prerequisite, a local scan (Gen'ed) must be performed on the scan target storage system.
• Deleting a volume range from a volume range list, page 71 • Restrictions for deleting volume ranges, page 71 Adding a volume range to a volume range list To add a volume range to the volume range list: 1. Display the list of disk configuration definition files on the Disk Configs tab in the BC Manager / Mainframe Agent subwindow. For details on how to display disk configuration definition files, see “Displaying disk configuration definition files” on page 75. 2.
• Overlapping volume ranges cannot be specified. • When Non Gen'ed scan or Remote scan is selected, a starting number of Dummy DEVN that would cause the value of Dummy DEVN to exceed FFFF during the volume scan cannot be specified. Deleting a volume range from a volume range list To delete a volume range from a volume range list: 1. Display the list of disk configuration definition files on the Disk Configs tab in the BC Manager / Mainframe Agent subwindow.
2. Select a disk configuration definition file. 3. Set the volume range for the scan. For details, see “Adding a volume range to a volume range list” on page 70. 4. Select the target hosts for disk list distribution. For details, see “Selecting targets for disk configuration distribution” on page 74. 5. Check the information and click OK to begin the volume scan. The scanning process may take some time.
Example disk list distribution scenario Prerequisites for distribution destination hosts (disk configuration definitions) HP StorageWorks P9000 for Business Continuity Manager Software or P9000 mainframe agent hosts (with disk configuration definition files) must satisfy the following conditions to be distribution destination candidates: • The DADIDs of the distribution destination candidate host are the same as the origin of distribution.
Conditions Whether volume has been added to a pair* Copy type Volume type Information displayed when no restrictions apply to resource groups Information displayed when restrictions apply to resource groups Only the DADID of the volume added to the pair is displayed. Only the DADID of the volume added to the pair is displayed.
5. To delete a distribution target, deselect the check box for the candidate distribution host. TIP: The copy group definition file will not be distributed if you deselect a host registered as a distribution target. 6. To distribute the disk configuration definition file when the disk list is created, select the Distribute the disk config when creating the list check box. (Uncheck this check box when you want to skip disk list distribution.) 7. Click OK.
To edit a disk configuration definition file: 1. From the Explorer menu, choose Administration and then Information Source. The Information Source subwindow appears. 2. Expand the object tree, and select BC Manager / Mainframe Agent. The BC Manager / Mainframe subwindow appears. 3. Click the Disk Configs tab. The list of disk configuration definition files managed by Replication Manager are displayed in the Disk Configs tab. 4.
3. Under the DEVNs tab, select the Paired tab. The paired DEVN list is displayed. This list also displays copy types associated with established copy pairs. 4. Review the information in the paired DEVN list. Related topics • Reviewing unpaired DEVN list, page 77 • Reviewing unpaired LDEV list, page 78 Reviewing paired LDEV list To review the paired LDEV list: 1. From the Explorer menu, choose Resources and then Storage Systems. The Storage Systems subwindow appears. 2.
Reviewing unpaired LDEV list To review the unpaired LDEV list: 1. From the Explorer menu, choose Resources and then Storage Systems. The Hosts subwindow appears. 2. Expand the object tree, and then select a storage system under Storage Systems. The storage-system-name subwindow appears. 3. On the CUs tab, select a control unit number. The CU-number subwindow appears. 4. Under the LDEVs tab, select the Unpaired tab. All Mainframe volumes located on the storage system are listed. 5.
6 Setting up authorities Before you can use Replication Manager, you must specify user account settings and permissions to restrict the scope of operations allowed for each user. Replication Manager controls access by using resource groups that restrict accessible ranges, and user management roles that restrict user operations. To control access to Replication Manager resources, you need to create resource groups and associate users with resources. This chapter describes how to configure access control.
Permissions and management roles In addition to the built-in account (user ID: System), there are permissions that grant access to all Replication Manager functions. Permissions can be allocated in any combination, but are broad in nature and do not control access to individual functions. The following table groups the permissions into two categories known as management roles.
are fixed and cannot be customized.The user roles and their capabilities are shown in the following table. Table 3 User roles User Role Description Storage administrator Responsible for all replication tasks, including resource allocation (S-VOLs). Copy pair administrator Responsible for all replication tasks, except resource allocation. Application administrator Responsible for data protection of applications, but cannot change pair configurations.
Basic (mainframe and open) Advanced (open only) Role Create Delete Application operator Resync/split Restore Takeover Swap Force-split Takeover-Recovery X TIP: In most cases, assignment of the roles determines whether a function can be performed by disabling the control or button on a given window (for example, by dimming the Create button). For some functions, the controls may not be displayed at all.
Role Launch Pair Configuration Wizard (Allocate S-VOLs) Launch “Edit Workflow” window (Define Copy Groups) Launch Change Pair Status Wizard (Create/delete copy pairs, restore copy pairs) Launch Restore Replica Wizard Application Administrator Disabled Disabled Enabled1 Enabled Disabled Disabled Enabled1,2 Disabled Application Operator Legend: 1. 2. Create/delete operation is not available; restricted operations are not listed on the Operations field of the Change Pair Status Wizard.
Changing user permissions You can specify the permissions required to use a specific P9000 Command View AE Suite product for each registered user. To allow existing P9000 Command View AE Suite product users to also use Replication Manager, you must grant Replication Manager management permissions to those users.
Setting up resource groups Replication Manager controls access by using resource groups that restrict the range of resources that can be accessed by users. To control access to Replication Manager resources, you need to create resource groups and associate users with resources. About resource groups A resource group is a collection of applications or sites that are grouped together and associated with specific users to restrict the resources that users can access.
Creating resource groups To create resource groups: 1. From the Explorer menu, choose Administration and then Resource Groups. The Resource Groups subwindow appears. 2. Click Create Group. The Create Resource Group dialog box appears. 3. Register the information about the resource group you want to create. The created resource group is displayed in the Resource Groups subwindow. 4. You can then add resources to the resource group as desired.
• • • • • About resource groups, page 85 Adding hosts to a resource group, page 87 Adding users to a resource group, page 88 Adding storage systems to a resource group, page 87 Adding applications to a resource group, page 89 Adding hosts to a resource group You can add hosts as resources to existing resource groups. TIP: You cannot register the same host in more than one resource group. In addition, you cannot add hosts to the All Resources group (where all hosts are registered automatically).
3. On the Storage Systems page, click Add Storage Systems. The Add Storage Systems - resource-group-name dialog box appears. 4. Select the storage systems you want to add, and then add them. The added storage systems are displayed on the Storage Systems page. Related topics • About resource groups, page 85 • Removing storage systems from a resource group, page 356 Adding users to a resource group You can add users to existing resource groups.
Adding applications to a resource group You can add hosts/applications as resources to existing resource groups. TIP: You cannot register the same host/application in more than one resource group. In addition, you cannot add hosts/applications to the All Resources group (where all hosts are registered automatically). To add hosts/applications to a resource group: 1. From the Explorer menu, choose Administration and then Resource Groups. The Resource Groups subwindow appears. 2.
3. On the Applications page, click Add Hosts. The Add Hosts - resource-group-name (Applications) dialog box appears. 4. Select the hosts/applications you want to add, and then add them. The added hosts/applications are displayed on the Applications page.
7 Organizing resources In Replication Manager you can organize resources such as hosts and storage systems into logical sites for easier management. You can also designate frequently monitored resource groups as My Copy Groups. This chapter describes different ways to organize resources. About resources Resources are entities managed by Replication Manager. These include application servers, storage systems, and pair management servers that constitute the replication environment.
Setting up sites Sites allow you to manually group resources under one name for easier management. You can define your own site and register resources such as hosts and storage systems. Grouping of resources into logical sites is especially useful when you have remote sites. Although you can define logical sites with any combination of resources, managing many resources from the web interface is easier when logical sites are created based on the resources of actual sites.
Adding sites To add sites: 1. From the Explorer menu, choose Shared Views and then Sites. The Sites subwindow appears. 2. Click Add Site. The Add Site dialog box appears. 3. Enter information about the sites you want to add, and then add them. The added sites are displayed in the Sites subwindow.
4. After sites have been added, specify the resources for the sites.
To add hosts to a site: 1. From the Explorer menu, choose Shared Views and then Sites. The Sites subwindow appears. 2. Expand the object tree, and then select a site by clicking on the site name in the Site List. The site-name subwindow appears. 3. Click the Hosts link. The Hosts subwindow appears. 4. Click Add Hosts. The Add Hosts dialog box appears. 5. Select the hosts you want to add, and then add them. The added hosts are displayed in the Hosts subwindow.
Adding pair management servers to a site You can add pair management servers to existing sites. After pair management servers have been added, the copy pair configuration definitions managed by the servers can be accessed from the nodes under the site. For open systems, if you need to use a pre-existing host as a pair management server (that is, you already added the host to the site), you must add the host to the site again as a pair management server.
3. Click the Applications link. The Applications subwindow appears. 4. Click the link for the desired application server. The Hosts list is displayed. 5. Click Add Hosts. The Add Hosts dialog box appears. 6. Select the hosts you want to add, and then add them. The added application servers are displayed in the Hosts list.
• Explorer menu items for My Copy Groups management , page 305 • My Copy Groups management functions, page 305 Examples of My Copy Groups The following figure shows a display example of My Copy Groups. Display example of My Copy Groups If the copy groups registered in My Copy Groups have a multi-target configuration or cascade configuration, the relationships among the copy groups are displayed as described below.
In this example, the secondary volume of Copy Group_A is the primary volume of Copy Group_B and Copy Group_C. If a single copy group is connected to multiple copy groups The secondary volume of the multiple copy groups on the left is the primary volume of the single copy group on the right. In this example, the secondary volume of Copy Group_A and Copy Group_B is the primary volume of Copy Group_C.
In this example, the secondary volume of Copy Group_C is used as the primary volume of Copy Group_D, the copy type of which is Business Copy. Example (2) In this example, the secondary volume of Copy Group_A is used as the primary volume of Copy Group_D and Copy Group_E, both of which have the Business Copy copy type. Example (3) In this example, the primary volume of Copy Group_A is also used as the primary volume of Copy Group_D and Copy Group_E, both of which have the Business Copy copy type.
Creating My Copy Groups To create My Copy Groups: 1. From the Explorer menu, choose My Groups and then My Copy Groups. The My Copy Groups subwindow appears. 2. Click Edit My Copy Groups. The Edit My Copy Groups dialog box appears. 3. In the list, select the copy groups you want to display in My Copy Groups. 4. Click OK to update My Copy Groups. The information displayed in the My Copy Groups subwindow is refreshed.
Organizing resources
8 Setting up storage systems You can use Replication Manager to replicate volumes or change copy pair definitions. It is necessary to configure prerequisite settings before replicating volumes. You can specify the prerequisite settings centrally from Replication Manager, for many storage systems across multiple sites. This chapter describes the tasks for preparing the replication environment and setting up storage systems.
For a list of available storage system setup functions and required user permissions (Replication Manager management), see “Storage system setup functions ” on page 104. NOTE: For mainframe systems: Depending on the copy types to be configured, some of the storage system setup operations need to be performed with Remote Web Console. For details, see the HP P9000 Replication Manager Software Configuration Guide.
• Create a new remote path • Add a remote port for an existing remote path. TIP: Each function can be used only for the resources in resource groups associated with the user. Explorer menu items for setting up storage systems The following table shows the Explorer menu items that are related to setting up storage systems, user permissions (Replication Manager management), and whether the items can be executed with the indicated permissions.
Flow of specifying the settings required before replicating volumes Setting up V-VOLs Replication Manager supports creation of V-VOLs on storage system configurations. This function is only supported for XP24000/XP20000 storage systems. You can create V-VOLs and associate them with volume pools, using the Create V-VOL wizard. For details on how to create V-VOLs, see “Creating V-VOLs” on page 108 About creating V-VOLs Replication Manager supports creation of V-VOLs on storage system configurations.
V-VOL limits The maximum number of V-VOL groups that can be created for each storage system is 65,280. For XP24000/XP20000 storage systems, the maximum number of V-VOLs in a V-VOL group is 1024. For HP StorageWorks P9500 storage systems, the default maximum number of V-VOLs that can be created at one time with the Create V-VOL Wizard is 900. (Exceeding this limit will fail with the error RPM-01014.) To increase this value, you must modify the server.http.entity.maxLength property in the server.
Conditions CVS has been installed CVS has not been installed Number of P-VOLs that can be added (in the Select Primary LDEV-Target LDEVs window) No limit 1 Number of Snapshot/Fast Snap copy generations (in the Primary LDEVs-Count of Snapshot window) 1024 1 (inactive) About the Create V-VOL Wizard Replication Manager includes a Create V-VOL Wizard for creating V-VOLs and associating them with volume pools.
2. Expand the object tree, and then select a storage system under Storage Systems. The storage-system-name subwindow appears. 3. Click the Open link. The Open subwindow appears. 4. Under the Pools tab, display the V-VOLs tab. 5. Click Create V-VOLs. The Create V-VOLs Wizard is launched. 6. On the 1. Setup V-VOL Group page, specify the parameters of the V-VOL Group (Parity Group). NOTE: Steps 7 and 8 only apply to XP24000/XP20000 storage systems.
17. Review all parameters of the V-VOLs and click Confirm. The 5. Finish page is displayed. TIP: The time taken to complete this operation depends on the count and size of the primary LDEVs, and the specified Count of Snapshot. For five 1 GB primary LDEVs, it takes approximately 20 minutes. For one 1 GB primary LDEV and 1024 snapshots, it takes approximately 40 minutes. This operation can take longer when a large number of primary LDEVs are selected. 18.

9 Customizing monitoring parameters You can customize Replication Manager by configuring alert notification settings, refresh intervals, and data retention periods. You can set up alerts to monitor thresholds for copy pair status, performance metrics and copy license usage. You can also configure refresh intervals at which the latest storage system information is applied to the Replication Manager database and retention periods for data items such as received alerts, write delay time, and event logs.
Copy pair status An alert is sent when a copy pair or copy group achieves a specified status. For example, you can specify a condition for a copy group so that an alert is sent when an error status is detected. In this case, an alert is sent indicating the copy pairs of the group that are in error status. When all the constituent pairs attain Completed status, the copy group is given the Completed status.
Monitored condition Completion criteria Write latency time (C/T delta) The write latency time must be less than or equal to the time specified by the user for the alert to be completed. Copy pair status When the status of the copy pair transitions out of the state specified for the alert. Copy group status When all of the pairs contained in the copy group are marked Completed. (Even if the status of pairs in the copy group changes again, the copy group alert remains Completed.
You can configure the following monitoring types depending on the resource type of the monitored target: • Pair Status Monitoring: You can set alerts to monitor pair status when the resource type of the monitored target is a copy pair or copy group type. • Performance Monitoring: You can set alerts to monitor performance information when the resource type is a copy group, pool, or journal group type.

Legend: Y: Can be executed with this permission. About the pair management wizards Replication Manager provides two pair management wizards. The Pair Configuration Wizard is provided for the creation and editing of copy pair configuration definitions. The Change Pair Status Wizard allows you to change the copy pair status.
Pair configuration workflow The following figure illustrates the workflow for pair configuration. Launching the Pair Configuration Wizard You can launch the Pair Configuration Wizard from the following locations on the web interface: • Unpaired LUN List: The Unpaired LUN list does not include copy pairs. The wizard can be launched from this list to configure new volume pairs. • Paired LUN List: The Paired LUN list includes copy pairs.
NOTE: The term LUN (Logical Unit Number) only applies to open systems. For mainframe systems, the analogs are LDEV (Logical Device) and DEVN (Device Number). Method for launching the wizard Conditions when the wizard cannot be launched • The LU has been reserved by another workflow. • The LU is a virtual volume. • If the LU is an internal volume to which an external volume is mapped, the host I/O suppression mode is enabled.
Method for launching the wizard Conditions when the wizard cannot be launched • A copy group that belongs to the same cascade has been reserved by another workflow. • At least one of the selected volumes does not belong to the same copy group. • A copy group in the same cascade contains pairs of multiple copy types. • Replication Manager is not aware of the pair management server (on either the primary or secondary side) that manages copy groups belonging to the same cascade.
Defining copy pairs and pair groups This module discusses how copy pair configuration definitions are created and tasks for defining copy pairs and pair groups: • • • • • • • About copy pairs, page 143 About copy pair configuration definitions, page 145 About creating copy pair configuration definitions, page 146 Creating pairs and pair groups, page 150 Editing pair names, page 152 About filtering candidate volumes, page 152 Selecting multiple candidate volumes, page 153 About copy pairs A copy pair is a
• Secondary volume (S-VOL): The destination volume to which the contents of the primary volume are copied. • Secondary-primary volume (SP-VOL): The volume located in the middle of a cascade configuration. A secondary-primary volume is both the secondary volume in an upper-level copy pair and the primary volume in a lower-level copy pair.
About copy pair configuration definitions Copy pair configuration definitions are generated when a new copy group is created. Pre-existing copy pair configuration definitions can also be imported into Replication Manager. New copy pair configuration definitions are created and edited using the Pair Configuration Wizard.
About configuration definition file formats New configuration definition files (HORCM configuration files) can be generated in either HORCM_LDEV format or HORCM_DEV format. Replication Manager allows you to specify the format for new configuration definition files using the server.agent.rm.pairDefinitionForm and server.agent.rm.cuLdevForm properties in the Device Manager agent server.properties file.
on permitted copy types for copy pair configuration definitions for different storage system types, see “Storage system conditions for pair configuration definition” on page 148. TIP: Use the latest versions of the storage system's microprogram and P9000 RAID Manager.
Prerequisites for pair configuration The following items need to be verified before performing pair configuration operations. Open • The storage system P-VOL and S-VOL are registered to Device Manager and the Device Manager instance is registered as an information source. If using a copy type, a remote path is set. If selecting an LU, it must not be associated with a device group.
Conditions for primary volumes that can be added (open systems) The primary volumes that are displayed in the Candidate List pane on the 2. Pair Association page of the Pair Configuration Wizard depend on the copy type and the storage system type. Volumes that satisfy all of the following conditions are displayed: • The volumes must belong to the same storage system displayed in the Pair List. • When the copy type is Snapshot/Fast Snap or Continuous Access Journal, the emulation type must be OPEN-V.
• When the copy type is Continuous Access Journal, the storage system must be different from that of the primary volume, and the storage system type must be XP12000/XP10000/SVS200, XP24000/XP20000, or HP P9500. • • • • The volumes must not be command devices or remote command devices. The volumes must not be virtual volumes. The volumes must not be reserved by other workflows. The volumes must be internal volumes to which the external volumes are mapped, and the host I/O suppression mode must be disabled.
To create pairs and pair groups: 1. Display the information about the host or subsystem on which you want to create a copy pair. For details on how to display the information, see “Viewing individual host information” on page 294 or “Viewing individual storage system information” on page 295. 2. In the displayed subwindow, select the Unpaired tab under the LUNs, DEVNs, or LDEVs tabs. 3. On the Unpaired tab, select the primary volumes from which to create a copy pair, and then click Pair Management.
6. Click Next to continue creating the copy pair configuration definition or click Save to temporarily save the workflow. The primary and secondary volumes need to be configured in a one-to-one correspondence before you can continue pair configuration.
• Selecting multiple candidate volumes, page 153 • Creating pairs and pair groups, page 150 Conditions affecting displayed storage system information The storage system information displayed in the Storage System drop-down list in the Criteria tab (on 2. Pair Association page) differ depending on multiple conditions. The following table shows the information displayed based on various conditions: Conditions No volumes selected. One or more volumes selected.
NOTE: The number of cylinders cannot be obtained when using HP StorageWorks P9000 for Business Continuity Manager Software versions prior to 6.7.0.
About assigning CTGID/JNLGID for copy pairs Consistency groups and Journal groups can be configured for any asynchronous copy pair. Replication Manager allows you to assign CTGID/JNLGID for copy pairs during pair creation (when associating a pair group to a copy group). In order to change a CTGID/JNLGID, it is necessary to delete and recreate the copy pair. TIP: Take note of the following: • CTGID/JNLGIDs are independent among storage systems.
3. 4. Use the Pair Configuration Wizard (mainframe) to define the mainframe Cnt Ac-S pairs. On the 3. Group Management page, perform the following: 1. Assign the same CTGID as the one you confirmed in step 2. 2. Specify the Enable Open/MF CTG option in the Edit Group dialog box. Use HP StorageWorks P9000 for Business Continuity Manager Software to create pairs for the pair definition configured in step 3. When configuring existing pairs 1.
Creating copy groups A copy group is created by assigning copy pairs to a pair group. For open systems pair configuration, copy groups can be created on the 3. Group Management page of the Pair Configuration Wizard. TIP: If you need to stop the wizard before the copy pair configuration definition is completed, it can be temporarily saved as a workflow. For more information, see “Saving workflows” on page 174. To create a copy group: 1.
Associating pair groups with copy groups To associate pair groups with a copy group: 1. If you are creating a copy pair configuration definition from a saved workflow, perform the following: 1. From the Explorer menu, choose Tasks and then choose Workflows. A list of saved workflows is displayed. 2. 2. Select a saved workflow and click Edit Workflow. On the 3. Group Management page of the Pair Configuration Wizard, select the pair group to be associated with the copy group. 3.
Creating a container with multiple copy groups (mainframe systems) To create a container with multiple copy groups: 1. Select a volume without a copy pair configuration and launch the Pair Configuration Wizard. For details on how to launch the Pair Configuration Wizard, see “Launching the Pair Configuration Wizard” on page 140. 2. Create a pair group and associate it with a copy group. When performing the association, specify the consistency group ID and journal group ID.

Create Continuous Access Synchronous and Continuous Access Journal pair groups in a multi-target configuration.
TIP: For situations such as when storage system resources and host applications are managed by different administrators, the work status at any point during copy pair creation by a wizard can be saved as a workflow and passed from one administrator to the next. In this case, a new task is generated when the wizard finishes and the saved workflow is overwritten. Because associated tasks have an execution order, a task that must be executed prior to another task is known as a prerequisite task.
About task statuses Tasks can be in one of the following execution statuses: • • • • Ready: Indicates that the task is waiting to execute. Executing: Indicates that the task is executing. Cancel: Indicates that the task was canceled. Failure: Indicates that the task failed. When you select Failure, an error window appears. Read the message in the error window. • Success: Indicates that the task was successful. • Warning: Indicates that the system timed out while waiting for the task to finish processing.
• About task types (mainframe systems), page 167 • About tasks, page 164 About task types (mainframe systems) The following are task types displayed for mainframe systems: • modify file (create): Adds a pair definition to a copy group definition file. This type of task only creates or edits a copy group definition file. It does not create the defined pair. • modify file (delete): Deletes a pair from a copy group definition file. This type of task only deletes or edits a copy group definition file.
To edit tasks: 1. From the Explorer menu, choose Tasks and then Tasks. The Tasks subwindow appears. 2. To edit a single task, click the associated icon. To edit multiple tasks, select the check box of each task you want to edit and click Edit Tasks. The Edit Task(s) dialog box appears. 3. Specify the following options on the Task Options tab: Execution Request Time Modify Pair Configuration File Only (Do not create Pair) check box 4. Executes the task at a specified date and time.
2. On the Task Options tab, edit the execution schedule by selecting Execution Request Time options. 3. Enable the Modify Pair Configuration File Only (Do not create Pair) option if you do not wish to create the pairs. This option is always enabled during mainframe pair configuration because only pair configuration definition can be performed by Replication Manager. Mainframe copy pairs are not created by Replication Manager upon completion of pair configuration definition. 4.
2. Select the check boxes of the tasks you want to cancel, and then click Cancel Tasks. The Cancel Tasks dialog box appears. 3. Confirm the tasks that will be canceled, and then cancel them. The information in the Status and Execution Request Time columns for the tasks displayed in the Tasks subwindow is refreshed.
configuration, Replication Manager distributes the copy group list created during pair configuration to these distribution targets. The following two types of copy group definition file distribution are possible: • Normal distribution: Distribution of copy group definition file from the user-selected BCM or P9000 mainframe agent host to the target BCM or P9000 mainframe agent host. The copy group definition file is distributed to all hosts that satisfy the distribution prerequisites.
• The primary and secondary DADIDs defined in the copy group definition file at the origin must be defined in the copy group definition file at the destination. • The disk configuration definition files must already be distributed to the distribution destination host before the copy group definition files can be distributed. • The distribution destination BCM or P9000 mainframe agent host has required access permissions.
CAUTION: There is no way to recover the latest copy group definition files once all the copies of the files have been replaced with old files. This situation can be avoided by excluding the primary hosts of any old copy group definition files from being the target primary host.
TIP: For situations such as when storage system resources and host applications are managed by different administrators, the work status can be saved as a workflow at any point during copy pair creation and passed from one administrator to the next. In this case, a new task is generated when the wizard finishes, and the saved workflow is overwritten.
Related topics • About workflows, page 173 Editing workflows You can edit a workflow that was temporarily saved before it was completed in the Pair Configuration Wizard. When editing an unfinished workflow, you can restart the Pair Configuration Wizard from the step when the workflow was saved. You can also edit a workflow after pair configuration is completed (that is, a workflow for which Finish is displayed in Steps).
2. Select the check boxes of the workflows you want to delete, and then click Delete Workflows. TIP: A workflow that was saved in a step prior to the Pair Configuration Wizard (3. Group Management) page cannot be edited or deleted. Therefore, if you click either of these buttons, an error message (RPM-00451) appears. A workflow that was saved in the Pair Configuration Wizard (3. Group Management) page or later can be edited or deleted.
TIP: You cannot edit user-specified parameters such as copy group name, port number and instance number after the copy pair configuration definitions are created using the Pair Configuration Wizard. If these parameters need to be edited, it is necessary to manually modify the copy pair configuration definitions outside of Replication Manager. A number of conditions can affect the copy pair configuration definition settings.
• The startup mode values of BCM Agent initialization parameters must be set to EDIT (default value is MONITOR). If a configuration definition is updated or copy pair status is changed when the startup mode value is MONITOR, a BCM Agent error will occur. TIP: If you want to use an IPv6 connection or SSL communication between Replication Manager and BCM, IHS must be set up. For details about setting up IHS, refer to the HP StorageWorks P9000 for Business Continuity Manager Software documentation.
Editing copy groups by associating new pair groups To edit an existing copy group by associating new pair groups: 1.

This option applies only to XP24000/XP20000 and VP9550 storage systems.
To delete a copy group: 1. In the Hosts view, Storage Systems view, or Pair Configurations view, display information about the copy group for which you want to edit a copy pair configuration definition. For details on the Hosts view, Storage Systems view, and Pair Configurations view, see the following: 2.
TIP: In mainframe systems, you cannot delete all pairs that are in an existing copy group. This restriction prevents deletion of copy groups with distribution relationships. For details of conditions that disrupt copy group linkage, see “Conditions that disrupt copy group distribution relationships” on page 172. To delete copy pairs from a copy group: 1.
Importing existing configuration definition files To import existing copy group configuration definition files: 1. Confirm the following prerequisites: • Ensure the file specification format is is supported by Device Manager agent. Verify that the parameters in the configuration definition file satisfy the settings restrictions for each parameter.
• When new copy pairs are added to a pre-existing configuration definition file that has mixed formats, Replication Manager determines the format for the new copy pairs using the server.agent.rm.pairDefinitionForm property in the Device Manager agent server.properties file. The preexisting format parameters are left as is. After modification, both HORCM_LDEV and HORCM_DEV formats are supported in the same configuration definition file.

The copy pair status can be displayed at various levels: for example, for an individual copy group, or for the type of volume replication functionality (the copy type). The status of the copy pair within that grouping that has the most serious (highest priority) status is referred to as the summary pair status. The priority of copy pair statuses, starting from the most serious, is as follows: 1. 2. 3. 4. 5. 6.

TIP: As of Replication Manager version 6.3, mainframe pair status information can be obtained using Device Manager (without HP StorageWorks P9000 for Business Continuity Manager Software or P9000 mainframe agent installed). Detailed pair state information for mainframe pairs in Device Manager is equivalent to the information for open systems pairs shown in Table 11.
About changing copy pair status Replication Manager allows you to change the copy pair status in open and mainframe systems. Pair status change operations may be necessary to resume copy operations after recovery from an error or unexpected pair status changes. For open systems, you can perform the split, resync, restore, create and delete operations when the storage system type is XP12000/XP10000/SVS200 or XP24000/XP20000.
• Changing the copy pair status for multiple copy pairs (batch operation), page 228 Pair status transitions (when the target is a copy group) The following table lists possible pair status transitions for each combination of copy pair state and copy type, when the target is a copy group.

TIP: The operation that can be selected is determined based on the copy directions of the definition and entity and on the pair status. The Resync option or the Restore option is displayed for pair operations depending on whether the FORWARD or REVERSE option is specified when the SUSPEND status is set. For Business Copy copy type, this check is not performed and you can select both the Resync and Restore options.
TIP: Note the following: • When the wizard finishes processing, a task is automatically registered for each copy group. You cannot edit these tasks because the copy pair status is changed immediately. However if the processing takes time, you can check the task execution result later. • You can register a maximum of 100 workflows and a total of 1,000 tasks, including the tasks for creating and editing copy pair configuration definitions and changing the copy pair status.

6. On the Tasks window, verify task has completed by checking if the task status is Success. Related topics • About copy pair status, page 202 Advanced pair operations and recovery scenarios In addition to the basic pair operations (such as split and resync), the Change Pair Status Wizard supports several advanced operations for open system pairs.
CAUTION: Take note of the following points: • Advanced operations can be performed per copy group or per copy pair. • Because the copy pair status cannot be retrieved in the event of a failure, it is not confirmed prior to executing an operation. (Under normal circumstances, copy pair status confirmation is required and is performed by the Device Manager agent.) In this instance, an error message is created based on the information sent from the agent and is output for the Change Copy Pair Status task.
Swap operation This operation is used to switch work from the primary site to the secondary site. When you execute this operation, the primary volume and secondary volume for the copy pair are switched. The swap procedure is as follows: 1. Using the Change Pair Status Wizard, create a swap Change Copy Pair Status task for the target copy group or copy pair. 2. Check the Task List window to confirm that the status of the task is Success. 3. Check the copy pair status in the Pair Configurations view. 4.
takeover-recovery operation depend on the options specified, so you must check the copy pair status and select the options accordingly. The table below lists the options for the takeover-recovery operation and the status of the target copy pairs.

• P9000 RAID Manager response time and virtual command devices, page 246 About virtual command devices Command devices are used to send P9000 RAID Manager commands between the pair management server and a storage system. Command devices use the FC link (known as an in-band connection). Virtual command devices allow you to perform the same operations using the LAN (known as an out-of-band connection).
The following figure shows a Virtual Command Device server configuration. The server connected to the actual command device is set as the virtual command device on each pair management server or application host. The Virtual Command Device server can be the same machine as the P9000 RAID Manager server. Figure 10 Configuration with Virtual Command Device server Prerequisites for virtual command device configurations The following requirements apply to virtual command device configurations.
Target Pair Management server Storage system Prerequisite Device Manager agent 7.1.0 or later and P9000 RAID Manager 01-25-xx/xx or later must be installed. The configuration definition file is in a format that is supported by Device Manager agent, and the P9000 RAID Manager instance must have started normally. The serial numbers of the storage systems managed by the Device Manager server must be unique.
To set up an SVP as a virtual command device: 1. Change the account used for execution of the Device Manager agent service to an account with Administrator permission. (The default is the LocalSystem account.) 2. Specify the IP address of the SVP in the HORCM_CMD section of the HORCM configuration file. 3. Add copy groups to the HORCM configuration file. 4. Execute the raidcom -login command on the server managing the HORCM configuration file. 5. Perform a storage refresh from Device Manager. 6.
6. Perform a storage refresh from Device Manager. 7. If you using a remote Device Manager, follow the procedure for “Refreshing configuration information manually for each information source” on page 267. The new copy groups are displayed in the Copy Groups table of the Hosts view. Once these steps are complete, you can perform pair operations using the new resources.
Performing user authentication for replica operations When performing replica operations using command devices and P9000 RAID Manager authentication is enabled, you must execute the OS commands described in this procedure: 1. Start the P9000 RAID Manager instance that will be used by Application Agent: P9000-RAID-Manager-instance-location\etc\horcmstart P9000-RAID-Manager-instance-number 2.
Monitoring and management of copy groups defined by device group Copy groups defined by device group enable you to manage the LDEVs in a storage system as a single entity, allowing operations to be performed in batch mode. NOTE: As of release 7.1.
Prerequisites for copy group configurations defined by device group The following requirements apply to copy groups defined by device group. Target Prerequisites • The management server has been discovered as a pair management server in Replication Manager on the pair management server. (If performing discovery of copy groups defined by device group at a remote site, you also need to refresh the Device Manager configuration on the remote site.

11 Refreshing management information This chapter describes ways to refresh configuration and copy pair status information. About refreshing management information To maintain operability, Replication Manager has its own database for storing information about managed resources.
If you change the replication configuration, make sure that you refresh the configuration information before you refresh the copy pairs.
Explorer menu Permissions Submenu Menu command Admin Modify View My Groups My Copy Groups Y Y Y Settings Refresh Setting Y Y N Administration Maintenance Y N N Legend: Y: Can be executed with this permission. N: Cannot be executed with this permission.
Copy pair statuses can be refreshed manually (from a subwindow) or automatically (at an interval preset in the refresh settings). Normally, refreshing takes anywhere from a few to tens of minutes total. However, if the Device Manager refresh function is used (because there are copy pairs not managed by pair management servers in open systems), refreshing can require anywhere from a few to tens of minutes for each storage system.
Refreshing copy pair statuses data flow (mainframe systems) The following figure shows the flow of data when copy pairs are refreshed in mainframe systems.
Disabling the Device Manager refresh function In open systems where all copy pairs are managed by pair management servers, you should prevent the Device Manager refresh function from executing during a manual refresh. If this function is used to refresh copy pair statuses, processing time increases. TIP: If copy pairs have been defined using storage management software such as Remote Web Console, no configuration definition file exists. Such copy pairs are not managed by pair management servers.
4. Select the Do not execute a Device Manager refresh operation during a manual refresh operation check box, and then apply the new settings. The settings specified in the Monitoring Setting subwindow are updated. Thereafter, a manual refresh acquires information from the Device Manager agent on each pair management server (not from the database of the instance of Device Manager on the management server).
Refreshing copy pair statuses manually for each copy group To refresh copy pair statuses manually on a copy group basis: 1. Display the information about the copy group for which you want to refresh copy pair statuses. For details, see “Viewing information about copy groups belonging to a host” on page 297 or “Viewing information about copy groups belonging to a copy pair configuration definition” on page 295. 2. Click Refresh Copy Group or Refresh Copy Groups to start a refresh operation.

To refresh the copy pair status automatically for each information source: 1. From the Explorer menu, choose Settings and then Refresh Setting. The Refresh Setting subwindow appears. 2. Click the Monitoring Setting link. The Monitoring Setting subwindow appears. 3. Click the icon of the information source from which you want the copy pair status to be acquired automatically.
2. Click the Monitoring Setting link. The Monitoring Setting subwindow appears. 3. Click the link that has the name of the Device Manager server that is an information source to which the pair management server belongs. The Device-Manager-server-name subwindow appears. 4. Click the icon of the pair management server from which you want the copy pair statuses to be acquired automatically. The Edit Interval of Refresh Pair Status - pair-management-server-name dialog box appears. 5.
• Adding or deleting storage systems • Adding or deleting hosts • Adding or deleting copy pairs using the CLI For storage controlled by a remote instance of Device Manager, a manual refresh can be performed at any time as described in “Refreshing configuration information manually for each information source” on page 267, or it can be refreshed automatically.
Periodic refreshing When the periodic refreshing of configuration information is enabled, the latest configuration is acquired from the information source regardless of a storage refresh operation in Device Manager. For this option, you should specify a configuration refresh interval for acquiring the latest configuration information as described in “Refreshing configuration information automatically (using the refresh settings)” on page 266.
Data flow when configuration information is refreshed in mainframe systems The following figure shows the flow of data when configuration information is refreshed in mainframe systems.
Refreshing configuration information automatically (using the refresh settings) To minimize effects on operation, determine the refresh interval and start time carefully so that configuration information is refreshed while machine use is not heavy. You can also disable periodic refreshing if the configuration does not change. NOTE: Only remote instances of Device Manager are displayed. The local instance of Device Manager is refreshed automatically.
To refresh configuration information automatically: 1. From the Explorer menu, choose Settings and then Refresh Setting. The Refresh Setting subwindow appears. 2. Click the Configuration Setting link. The Configuration Setting subwindow appears. 3. Click the icon of the information source where you want to acquire configuration information automatically. The Edit Interval of Refresh Configuration - information-source-name dialog box appears. 4. Set and apply a refresh interval and refresh start time.
2. Select a storage system and click Refresh Storage System. The configuration information displayed in the Storage Systems view subwindow is refreshed. For details, see “Viewing a list of storage systems” on page 293.
12 System monitoring Replication Manager provides multiple ways to monitor the operating status of the replication environment. You can monitor frequently viewed copy groups, check pair statuses, pair configurations, and the performance of remote copies. This chapter describes the different types of system monitoring functions supported by Replication Manager. About system monitoring Replication Manager allows you to perform the following types of system monitoring functions.
Monitoring resource utilization You can monitor the usage ratio of buffers (pools and journal groups) and receive alerts by email or SNMP traps based on the predefined thresholds. If you are an administrator, you can add volumes to the buffers using Replication Manager. Monitoring copy license usage You can monitor the used capacity and copy license usage percentage for each copy product in complex replication environments.
Checking copy pair configurations Replication Manager provides multiple ways to check copy pair configurations. For details on how to check copy pair configuration, see: • Checking copy pair configuration definitions, page 271 • Checking copy pair configuration (perspective of specific volume), page 272 • Checking copy pair configuration (perspective of specific copy group), page 273 Copy pair configuration check workflow The following figure shows the flow of tasks for checking copy pair configurations.
2. Expand the object tree nodes. Expand the tree nodes for the pair management server in the navigation area. 3. Check the copy pair configuration. Check the copy groups defined in the configuration definition file or the copy group definition file (prefix). When you select a copy group, you can view a list of copy pairs belonging to the copy group.
2. Select a volume. In the displayed list, select the volume (LUN or DEVN) where you want to check the copy pair configuration to display information. For a storage system that connects to mainframe systems, before selecting the volume, select the applicable LDKC and CU for the model. 3. Check the copy pair configuration. In the list of copy pairs related to the selected volume, check the copy pair configuration.
2. Expand the object tree, and then select a pair management server under Pair Configurations. The pair-management-server-name subwindow appears. 3. Select a configuration definition file. The information about the configuration definition is displayed. Related topics • Viewing a list of copy pair configurations, page 292 • About configuration definition file formats, page 146 Viewing prefix information (mainframe systems) To view prefix information: 1.
you can specify an alert is sent when a given error status is detected. In this case, an alert is sent when any of the copy pairs belonging to the copy group enters the error status. TIP: Because you can receive alerts by way of email or SNMP traps, you can also monitor the replication environment without being logged on to Replication Manager.
Icons representing the relationship between a volume and a copy group Replication Manager uses icons representing volumes and copy groups and icons representing direction to indicate the relationship between a volume and a copy group. The following table lists and describes the icons that represent the relationship between a volume and a copy group: Icons representing the relationship between a volume and copy group Icon Description Indicates a primary volume.
Icon Description There is another copy pair connected in the cascade format to the copy pair's primary volume. There is another copy pair connected in the cascade format to the copy pair's secondary volume.
Checking the copy pair status Replication Manager provides multiple ways to check copy pair statuses: • “Checking status of copy pairs associated with volumes belonging to a host” on page 279. • “Checking status of copy pairs for a volume in a storage system” on page 279. Related topics • Copy pair status check workflow, page 278 About copy pair status checks Replication Manager provides multiple ways to check copy pair status.
Checking status of copy pairs associated with volumes belonging to a host To check the copy pair status for a volume of a host: 1. Select a host. From the Explorer menu, either choose Resources and then Hosts or choose Shared Views and then Sites. Select the host that contains the copy pair whose status you want to check. 2. Select a volume. In the displayed list, select the volume (LUN or DEVN) included in the copy pair whose status you want to check.
3. Check the copy pair statuses. In the list of copy pairs related to the selected volume, check the copy pair status, copy pair state, and copy progress for each pair.
Replication Manager can also be used to monitor asynchronous remote copying performed using Continuous Access Asynchronous or Continuous Access Journal. Write delay time or consistency time delta (C/T delta) can be monitored to acquire transfer delay status from volume replication facilities. You can display the transfer delay state between the primary and secondary volumes for each copy group.
• “Checking write delay time (C/T Delta) for each copy group” on page 283. Checking performance workflow (remote copies) The following figure shows the flow of tasks for checking the performance of remote copies.

4. Check the C/T delta. Use the copy group summary to check the C/T delta. For open systems, the difference between the data write times for the primary and secondary volumes is displayed. For mainframe systems, the difference between the secondary-volume consistency time and the current time is displayed for each consistency group. 5. Export the C/T delta history. If necessary, export the C/T delta history to a CSV or HTML file by clicking Export History.
3. Export the usage history of the buffers (pool volumes or journal volumes). If necessary, export the usage history of pools or journal groups to a CSV or HTML file by clicking Export History. Checking buffer usage (sidefiles and journal volumes) TIP: If you have registered the target copy group as one of your My Copy Groups, you do not need to use the following procedure. Instead, see “Refreshing copy pair statuses manually for My Copy Groups” on page 260.
Monitoring license usage Replication Manager assists in monitoring the license capacity, making it easy to track license usage, especially in large and complex replication environments. Replication Manager functions can be used within the licensed capacity of each copy product. Additional licenses are required when the target volumes for pair configuration exceed the licensed capacity.
Status Icon Description Critical No replica is available due to task failures. Unknown No replica is available as the task has not yet been created/executed. Excluded The object has been excluded from monitoring. Only displayed at the lowest level (information stores). When an object is excluded, the status of the object is not aggregated to the upper layer.
• If no instance of Critical exists, but one or more instances of Warning exist, the upper level is labeled Warning • If no instance of Critical or Warning exists, the upper level is labeled Normal This ensures that the current status of each level reflects that of the one below. In the example below, the top (application) level is tagged with an aggregate status of Critical.
3. In the Storage Groups tab (Exchange 2003/2007), click the desired storage group link. In the Information Stores tab (Exchange 2010), click the desired information store link. The Monitoring setting window is opened. 4. To exclude an information store from monitoring, clear the check box. 5. Click OK when your settings are complete. The status of the object changes to Excluded and is not aggregated to the upper layer. The latest replica is also ignored.

23 Managing application replicas This chapter describes how to manage application replicas using Replication Manager. About application replicas An application replica is a snapshot of an application server that is saved to a series of secondary volumes on an immediate or scheduled basis. As with copy pair management, the creation and management of application replicas is organized around tasks and storage assets. Replication Manager is used to create, manage, and (manually) restore replicas.
When selecting a secondary volume for a backup, you can either manually select the volume you want or use the default. To have Replication Manager choose a secondary volume for you, you need to use the volume copy function. When manually selecting a volume, choose the generation name unique to the desired volume.
Figure 13 Backup and restore operations Related topics • Creating an application replica, page 388 • Restoring the latest application replica (simple restore), page 395 About storage groups and information stores Storage groups are objects managed by Microsoft Exchange 2003/2007 to store databases. Multiple databases can be managed together because databases within the same group use a common transaction log.
Exchange 2010 does not use storage groups, therefore individual information stores are managed by Replication Manager. The following table lists which objects are eligible for Exchange replica operations.
Mount points If different logical volumes are mounted in multiple mount points with a hierarchical relationship (such as M:\ and M:\MNT) do not specify a mount point that includes a lower level directory mountpoint (for example, M:\ in the above instance) as the target of replication. If this is done, the replica creation fails and the error message (KAVX0006-E, DRM-10062) is output.
server and backup server is changed, from the Explorer menu, choose Administration and then Information Source. Choose the relevant server, and then click Refresh Agent to update the information. Deleting copy groups used for replica operations When an attempt is made to delete a copy group that is in a HORCM instance used by Application Agent, the Pair Configuration Wizard task may fail with the error message KAVN02521-E (RPM-00527).
• Data files to be stored on a particular disk drive must belong to the same instance. Data files from different instances must not be stored on the same disk drive. Mount status of secondary volumes Unmount all secondary volumes before performing a backup or restore to a database server. Failing to do so may cause unpredictable results. For example, P9000 RAID Manager might not operate normally, a mount or unmount operation might fail, or a data inconsistency might occur.
Use the following backup method to back up the databases: 1. Back up database A and database B concurrently. The replica 2010/8/31 07:14:00 is created. 2. Back up database A only. The replica 2010/9/06 08:15:00 is created. The following figure shows the correspondence of the backup catalog and copy group.
NOTE: After using a P9000 RAID Manager command to change the configuration of a copy pair, you should also execute a Refresh Storage System for the relevant storage system. For more information, see “Refreshing configuration information manually for each storage system” on page 267. • • • • • • • • • The mount point (drive letter for Windows) is changed. The disk configuration is changed by adding and removing a hard disk. The configuration of a database is modified.
• To back up an SQL Server instance, the instance must be online. If an attempt is made to back up an instance when it is not running, the attempt will fail. • If an instance contains multiple databases, the way volumes can be replicated or restored differs as follows, depending on the configuration of the primary volumes containing the databases: • When the databases are stored in the same volume, they can be replicated or restored at the same time.
Event type: Warning Event source: disk Event ID: 51 Event type: Warning Event source: ntfs Event ID: 50 These messages are displayed because the secondary volume is temporarily hidden during the backup. They have no impact on the operation and can be ignored.
Event ID : 15 Description : The Device XXXXXXXXXXXX is not the status that can be accessed. • The following event log may be output to the database server, the file server, or the backup server, and can safely be ignored: Event type : Warning Event source : VSS Event ID : 12333 Description : Warning of Volume Shadow Copy : The storageID that is not supported in VSS was reported from the provider.
• If Management Studio has been used to view the database to be restored, use Enterprise Manager to detach from the database or exit Management Studio before the restoration. • Match the configuration (drive name and path) of the restoration target SQL Server database with that used to create a replica to help ensure a successful restoration. If they do not match, the restoration will fail. • When a database is restored, the owner of the database is changed to the user who performed the restoration.
Figure 15 When the primary volume for BC and the primary volume for Cnt Ac-A are the same LDEV When using the configuration shown in Figure 15 to restore the paired volume for Business Copy, set the status of the paired volume for Continuous Access to SMPL or PSUS (SSUS). If you attempt to restore the pair volume for Business Copy with the status of a pair volume for Continuous Access PAIR, an error message indicating that the status of the copy group is invalid is displayed and the restore operation fails.
NOTE: Define one consistency group as one group (dev_group) of P9000 RAID Manager configuration definition files so that there are never too many or too few copy groups. For Exchange databases When restoring individual information stores: Define consistency groups to make each information store of data files (*.edb, *.stm) in the same consistency group. In addition, define consistency groups to make the transaction log files and checkpoint files (*.log, *.
• The files to be backed up must all be placed on a RAID volume defined as a pair. • For Exchange 2003/2007 servers, deploy the storage group taking into consideration that backups are conducted in units of volumes. If you deploy multiple storage groups in the same volume, you need to back up or restore these storage groups as one group. When backing up or restoring a storage group separately, deploy the storage group on a separate volume.
• Metafile directory (only when specified) • Transaction log backup files Roll-forward recovery processing can only be performed if the above directory and file are placed on separate volumes. (In the event of a restoration, this prevents the metadata and transaction log files from reverting to a previous state.) If this requirement is not satisfied, the backup terminates with an error.
• To restore system databases (master, model, and msdb) together with a database that uses the database mirroring function, disable the mirroring function for the database using it, restore the system databases, and then restore the database that uses the mirroring function. Allocating files that comprise a database Do not place database files to be backed up in the same volume as files that will not be backed up. Allocating metafiles A metafile is a file SQL Server outputs during backup processing.
Figure 17 Metafile allocation (in a cluster configuration) Using a cluster configuration Do not register the service resources of multiple SQL Server instances into a single cluster group. Software that should not be used during replica operations There are several tools and applications that can interfere with replica operations and should not be run while performing backups and restores.
Windows Indexing Service (cisvc.exe) Observe the following precautions with the indexing service: • Confirm that the master binder of the index service is not operating. File access by the index service can conflict with file operations of Replication Manager, which can cause an error in the index service master binding or in replica creation or restore processing. • Do not specify volumes that store the index service catalog.
Figure 18 Create application replica workflow About the Create Replica Wizard Replication Manager includes a Create Replica Wizard for creating snapshots of application servers. The Create Replica Wizard provides the following functions: • Choose to create a new task or edit an existing one, and select target objects. • Set options including the rotation of target volumes, execution options, and mount options (for tape backups). • Schedule the execution of the task.

8. The 3. Set Schedule page is displayed. 1. 2. To create the replica immediately (without a recurring schedule) select Execute immediately. For scheduled replica creation (single or recurring), select Execute on schedule, choose a Schedule Type, and select the applicable calendar options. NOTE: Do not create a schedule that will cause a copy pair to re-synchronize.
• Point-in-time When backup data on an Exchange Server or SQL Server database server is restored, the database returns to the state at the point-in-time when the backup occurred. If the transaction logs from the time when the backup was executed up until the restore are stored on the primary volume, the uncommitted transactions can be applied using the roll-forward option. By applying the transaction logs after backup, the database is restored to a state immediately before the error occurred.
Figure 19 Flow of operation using transaction logs (Roll-forward) After the database is backed up from the primary volume to the secondary volume at point A, the database is updated at point B. If an error occurs in a data file on the primary volume at point C and then the database is restored from the secondary volume to the primary volume, the database returns to the state it was in at point A.
Figure 20 Restoring data in units of information stores by applying transaction logs (roll-forward) The prerequisites for this example are the same as for the previous scenario, plus the following: • Only the data files (*.edb and *.stm) in the information store are stored on the same drive. • The transaction log file on the primary volume is not destroyed (roll-forward is executable). • Storage group SG1 has been backed up from the primary volume to the secondary volume.
• Configurations in which only information store data files (*.edb and *.stm) to be restored individually are stored on the same LDEV • Configurations in which multiple information store data files within the same storage group are stored on the same LDEV You can restore all information stores stored on the same LDEV provided that you specify all the information stores. In this case, if you do not specify all information stores located on the same LDEV, the restore operation will fail.
NOTE: The following restrictions apply: • When restoring backup data in units of information stores, you must apply (roll forward) the transaction log at the time of restoration. • To restore backup data in units of information stores, you need at least three LDEVs for one storage group. If you are using Continuous Access as the volume duplication function, up to two LDEVs can be backed up for a single storage group. This means that you cannot restore backup data in units of information stores.
Restoring the latest application replica (simple restore) TIP: This operation is available when all the target resources can be restored from a single replica. If target resources are managed by multiple tasks/replicas, see “Restoring an application replica from the Replica History” on page 396. To perform a simple restore of the most recent replica: 1. If you are restoring a replica located at a remote site to the local site, run the Change Pair Status Wizard and split the copy group. 2.
8. Choose the Restore Mode. • Point-in-time Restore: Restores the replica and the transaction logs (without committing the outstanding transactions). • Roll-forward Restore: Restores the replica and then commits any outstanding database transactions stored in the transaction logs. NOTE: A roll-forward operation cannot be performed for SQL Servers from within Replication Manager.
3. Expand the object tree, and then select a database server. The Server summary window appears. 4. Open the Replica History tab to view a list of replicas. 5. Select a replica and click Restore Replica. The Restore Replica Wizard is launched. 6. Follow the procedure in “Restoring the latest application replica (simple restore)” on page 395 starting at step 5.
2. Use the disk management function to unmount the primary volume connected to the database server. 3. Stop SQL Server on the backup server. 4. Select the replica associated with the volume in step 2 from the Replica History and click Unmount Replica. 5. Select the copy group, start the Change Pair Status Wizard, and select create. 6. Select the copy group, start the Change Pair Status Wizard, and select swap. 7.
Using Database Availability Groups (DAGs) Replication Manager supports Exchange Database Availability Groups (DAGs). In a DAG configuration, data mirroring occurs between the DAG active node and passive nodes. (The target server can be an active or passive node.) NOTE: The DAG feature is exclusive to Exchange Server 2010. For more information, see “About Database Availability Groups (DAGs)” on page 400.
• You cannot simultaneously create the replica of the active and passive mailbox database copies. Wait until execution of the replica creation is finished for the first mailbox database copy before you begin create the replica of the other mailbox database copies. • When you restore a replica, the target mailbox database copy must be an active mailbox database copy. • A replica can be restored only to the Exchange Server 2010 server where the replica was created.
Related topics • Using Database Availability Groups (DAGs), page 399 About SQL database and service status When Replication Manager is used to restore data from a secondary volume to a primary volume, the status of the database becomes either loading or standby: • Loading status (loading) The database can neither be viewed nor updated. • Standby status (read-only) The database can be viewed, but not updated.

POST_PROC: Post-processing specified by the user (after the backup command is issued). Table 26 Coding rules Applicable items Rules • The character code set must be ASCII. • Codes lower than 0x20 cannot be used, except for CR (0x0d), LF (0x0a), and TAB (0x09). Overall user script • The linefeed code must be LF (0x0a) or CR+LF (0x0d and 0x0a). • The length of a single line must not exceed 8 KB. • Do not execute a command that will display more than 2000 bytes of text.
NOTE: If command line execution from a user script times out, the task might remain in the Executing status. If this happens, perform the following procedure before re-creating the task: 1. Restart the Application Agent service. 2. Update the task information. 3. Revise the CMDLINE and TIMEOUT settings in the user script. Table 27 Script entries Entry name Meaning and specifiable values Multiple specification Omit LOCAL_BACKUP Specify YES.
Entry name Meaning and specifiable values Multiple specification Omit Not allowed Not allowed Allowed Allowed Specifies a command line to be executed. • If you want to specify an option, separate the command name and the option with a one-byte space character. • One command definition section must contain only one command line. • A maximum of 2048 characters can be specified on a command line. • A path or file name containing one or more spaces must be enclosed in double quotation marks (").
Entry name Meaning and specifiable values Multiple specification Omit Not allowed Allowed Not allowed Allowed Not allowed Allowed Not allowed Allowed Specifies the action to be performed in response to the return value of the executed command. Specifiable values are as follows: TERMINATE_NZ (default) Terminates script processing if a non-zero return value returns. IGNORE Continue processing whatever may be returned for a return value.
Environment variables The table below shows the Application Agent script environment variables that must be referenced by commands in the user post-processing section. These script environment variables can be referenced from the local server and the backup server. DRMENV_L_BACKUPID Backup ID of the local server. This environment variable is valid in the following cases: • The command is being executed in the local server. • The execution status of the parent command is normal.
Script text Explanation PARENT_STAT=NORMAL Execute only when the backup command is normal. Unmounting after an automatic mount If you specify the Automatically mount during the operation option while using the Create Replica Wizard, to automatically unmount the replica after the backup has been completed, you must execute the drmumount command. The Batch command file example demonstrates how to do this.
Preparing the user script and batch command file To prepare the script for execution from the Create Replica Wizard: 1. Save the user script file in any folder on the database server. You must supply this location in the Create Replica Wizard. 2. Save the batch command file in the directory C:\tmp on the backup server.
• SQL Server only: The database server must be set up with the default VDI Meta File Location in the SQL Options tab of the Setup Application Agent dialog box. • The backup server must be set as the tape backup destination by setting Replica Catalog Location in the Server Options tab of the Setup Application Agent dialog box. To save a replica to tape: 1.
• Select Execute pre/post jobs with Agent User Script and supply the path to a Script File located on the production server. TIP: If you set the Automatically mount during the operation option in the Create Replica Wizard, you should unmount the volume manually when the restore is complete. Command line tools Several command line tools to support tape operations are installed as part of Application Agent.
name containing space characters for the -f option, you must enclose the path name in double quotation marks ("). Return values are 0 for normal termination; any other value indicates an error. drmdbimport command The drmdbimport command imports, into a backup catalog, backup-information from a file that was exported by the drmdbexport command. Application Agent programs manage backup information based on copy groups, which are used as a key.
When the SQL Server replication function is used, the following requirements must be satisfied: • You must use the transaction replication type. • The name of the distribution database must be distribution, and only one distribution database can be created. • The subscription database must be restored separately from the system database (master, model, msdb), so the subscription database must be configured in a different volume than the system database.
Figure 26 Configuration of backup server for the publisher/distributor server (detail) Backing up the databases The publication database needs to be backed up at the same time as the distribution database. From the Select Target window of the Create Replica Wizard, select both the publication and distribution databases. Backing up the publication database transaction log Use Management Studio to back up the transaction log.
• For push subscription: use the publisher/distributor server. • For pull subscription: use the subscriber server. On the appropriate server, do the following: 1. Start the log reader agent. 2. Start the subscription agent. 3. Re-initialize the subscription, or remove and then recreate the subscription. Mounting and unmounting application replicas Replicas can be mounted or unmounted on the backup server as desired.
Checking the status of application replicas The status of application replicas is summarized in the Applications and Server subwindows. A set of icons represent how recent the replicas are, whether they have been created successfully, and so on. These icons are discussed in “About data protection status” on page 286. To check the data protection status of application replicas: 1. From the Explorer menu, choose Resources and then Applications. The Applications subwindow appears. 2.
2. Expand the object tree, and then select a database server. The Server summary window appears. 3. For Exchange 2003/2007, the Storage Groups tab allows you to view the storage groups associated with the server. For Exchange 2010, the Information Store tab allows you to view the information stores associated with the server. Clicking an object opens the Monitoring Setting window, which lists the information stores and Task ID links.
24 Handling errors This chapter describes error handling mechanisms supported by Replication Manager. About handling errors To monitor for errors occurring in a complex replication environment, you must acquire information that identifies the locations of errors. With Replication Manager, you can set alert conditions for monitoring entities such as copy pairs, copy groups, journal groups and copy licenses.
Event log management functions The following table shows the event log management functions, user permissions (Replication Manager management), and whether the functions can be used with the indicated permissions. Permissions Function Viewing a list of event log files Admin Modify View Y N N Legend: Y: Can be used with this permission. N: Cannot be used with this permission.
Icon Severity Description Error Indicates that the message describes an error related to the operation that was performed. Warning Indicates that the message shows a warning or confirmation for the operation that was performed or that is to be performed. Information Indicates that the message shows the processing status or result of the operation that was performed. Troubleshooting the replication environment For a diagram, see “Troubleshooting the replication environment workflow” on page 421.
NOTE: By default, alerts are automatically marked as completed when the pair leaves the monitored status. If the automarking feature has been disabled, the alert must be handled manually. See “Marking alerts as completed” on page 324 for more information. About MIB definition files You can check received SNMP traps using the MIB definition files provided by Replication Manager.
25 Exporting management information This chapter describes tasks for exporting management information. About exporting management information You can export Replication Manager management information to a file in CSV or HTML format. Using the exported file, you can determine the cause of an error, establish corrective measures, and analyze performance information. If necessary, you can edit the file or open it with another application program. You can export a maximum of 20,000 data items at a time.
Permissions Function Exporting event log files Admin Modify View Y N N Legend: Y: Can be used with this permission. N: Cannot be used with this permission. TIP: Each function can be used only for the resources in resource groups associated with the user.
3. Specify a time period for the information to be exported and the export format, and then export the information. The alert history is exported to a file. Related topics • About exporting management information, page 423 Exporting event log data To export event log data: 1. From the Explorer menu, choose Administration and then Event Logs. The Event Logs subwindow appears. 2. Click Export. The Export Event Logs dialog box appears. 3.
Using the GetCTDelta command In addition to the Replication Manager GUI, you can also export C/T Delta (write delay) history data from the command line. Using the GetCTDelta command, you can output the histories of all (or select) copy groups to a CSV-format file or the console. The command line is an alternative to generate the information quickly without the overhead associated with the GUI. GetCTDelta output is in CSV format.
• The file path can be either relative or absolute. • The command execution results are output to the specified file instead of the console. When this option is specified, • Do not specify a shortcut or symbolic link for the file path. [{ -h | --help}] • Displays the command usage. If you include other options or parameters when using the help option, they are ignored. Parameters Optional parameters can be used to specify the information to be exported.
NOTE: If you output the C/T delta history for a copy group defined in a device group, n/a is output for the pair management server and configuration file.

B Exceptions This appendix provides information about complex system configuration scenarios. Cautionary notes for the GUI display Certain cautionary notes exist for the GUI.
For open systems In the Hosts view or Storage Systems view, volumes to which paths have been specified are displayed in either the Paired or Unpaired list. The volumes constituting copy pairs are displayed in the Paired list and the other volumes are displayed in the Unpaired list. However, the volumes constituting copy pairs in simplex status are displayed in the Unpaired list, because they have been defined, but not yet created.
To view an example configuration in which two copy group definition files are used for the same copy group (for mainframe systems), see “Example configuration in which two copy group definition files are used for the same copy group (for mainframe systems)” on page 445.
When the copy pair configuration is complex For a complex configuration, such as one in which a copy group has two primary volumes, copy group configuration information cannot be displayed when copy groups are displayed in list format, as they are in the pair configurations view.
Example when two configuration files define an opposite relationship of primary and secondary volumes for the same copy group Example of complex cascade configuration 2 Example of when two pairs in a cascade configuration are defined in the same copy group When the displayed information depends on the system configuration In Replication Manager, displayed information might be limited by the system configuration. The following describes such limitations separately for open systems and mainframe systems.
• Name of the storage system to which a secondary volume belongs TIP: It is assumed that each Device Manager server has been registered as an information source of Replication Manager and that the pair management servers and hosts have been registered in the Device Manager server at each site. For a diagram, see “Example configuration in which data is remotely copied between multiple sites (for open systems) ” on page 449.
Example configuration in which data is remotely copied between multiple sites (for open systems) When multiple Replication Manager servers manage the same information source In configurations where multiple Replication Manager servers manage the same information source (DevMgr / BCM), the servers cannot simultaneously monitor and manage pairs.
When Replication Manager handles multiple prefixes (mainframe systems) Replication Manager allows you to confirm, define and operate copy pairs for multiple prefixes concurrently. On the Hosts or Storage Systems view you can confirm DEVNs and LDEVs without specifying or identifying the prefix. During pair configuration, Replication Manager prohibits selection of P-VOLs / S-VOLs from multiple prefixes on a mainframe host.
C Display formats This appendix provides information on supported display formats. Display formats used when no pertinent information is available If no pertinent information is available, several items are displayed in the GUI depending on the context: No object Indicates that Replication Manager cannot acquire the information because the information source does not exist. In this case, the connection with the information source must be re-established.
Indicates that no value is specified for the configuration information managed by Replication Manager Before this information can be displayed, a value must be specified for the information in Replication Manager. (This does not apply to hyphens contained in license information.) Blank Indicates that Replication Manager acquired blank information from the information source. (Unknown icon) or Unknown (For the summary copy pair status, the Unknown icon is displayed.

Glossary This glossary defines the special terms used in this document. Click the desired letter below to display the glossary entries that start with that letter. 3DC Multi-target configuration A configuration in which, in addition to the local site, a connection is established between a nearby remote site and a distant remote site and Continuous Access Synchronous and Continuous Access Journal are used to copy storage system volumes among the three sites (called a data center).
cluster configuration In a Replication Manager operating environment, the term cluster configuration refers to a configuration that consists of an executing node and a standby node, each of which includes a duplicate management server. cluster software Software installed on management server nodes to boost overall availability by duplicating management servers as a cluster system. Available software depends on the OS that runs on the management server.
copy pair status A value that represents the status of a copy pair. Six status values are defined in Replication Manager: error, suspend, copying, sync, simplex, and unknown. Each status is indicated by an icon. The copy pair status is determined by the combination of the copy pair states of the primary and secondary volumes. Also called pair status. copy progress Progress status of the volume replication functionality executed by the storage system.
Manager Software to manage volumes to which no DEVNs have been assigned by the mainframe host. Emulation Type The types of LUs with varying attributes supported by the XP1024/XP128, XP12000/10000/SVS200 and XP24000/20000 series. Also referred to as Emulation Mode. Extended Consistency Group (EXCTG) An attribute for maintaining data integrity between the copy pairs contained in consistency groups. In principle, each copy group container is assigned this attribute.
LAN Local Area Network LDAP Lightweight Directory Access Protocol LDEV (Logical DEVice) A volume created in a storage systemknown as an LDEV (logical device) in a mainframe system. It is a storage region created by dividing up an Array group storage region in the XP1024/XP128, XP12000/10000/SVS200 and XP24000/20000 series. The size of an LDEV is determined by the factory settings and the size of the drives that make up the Array group. An LU is made up of one or more LDEVs.
N:N configuration A configuration in which multiple configuration definition files are managed by both the primary volume server and the secondary volume server. Non-Gen’ed Scan A volume scan that can be performed on Non Gen'ed volumes within the site where HP StorageWorks P9000 for Business Continuity Manager Software resides. The Non Gen'ed DAD attribute is assigned to the disk configuration definition file in which the discovered volumes are stored.
