3 Discovering, registering, and adding management targets Managing storage resources requires them to be registered in HP XP7 Command View Advanced Edition software. Registration automatically occurs after discovery. Setting up storage resources Collectively, storage systems and hosts are called storage resources. For storage resources to be managed by XP7 Command View AE, they must first be discovered and registered.
• • • • • Parity Groups LDEVs Volumes THP/Smart pools Resources available through external storage connections When you specify IP address (or host name) and authentication information for a storage system, the storage system is discovered and registered based on the specified information. For Storage Management Initiative Specification (SMI-S) enabled storage systems, the SMI-S provider's IP address is used. You can modify information about a storage system after a storage system is registered.
NOTE: If the storage system is HP XP7, or HP P9500 you must select the Administrator user group (which is a built-in group) to register the accounts. • When using XP7 Command View AE authentication on an HP XP7 for SVP and RAID Manager logins, you must enable SSL communication on the Device Manager server. In addition, configuring firewall exceptions might be required. For details, see the HP XP7 Command View Advanced Edition Administrator Guide.
4. Click OK. 5. Check the Data Collection Tasks tab to verify that the task completed successfully. 6. When the task completes, confirm that the registered storage system appears on the Storage Systems tab of Managed Resources, or in the Storage Systems tree on the Resources tab. The storage system is now a managed resource and volumes can be allocated to managed hosts. TIP: To remove storage systems, select one or more storage systems, and click Remove Storage Systems.
TIP: When data placement profiles for Smart volumes are being managed, you can specify an option in the Refresh Storage Systems dialog box to search for inconsistencies in data placement profiles. To update information about hosts, such as the host name, WWNs, refresh the hosts. To update host bus adapter (HBA) WWN nicknames, refresh one or more storage systems. Refreshing host information does not update WWN nicknames.
The Storage Management Initiative Specification (SMI-S) defines software development standards in support of storage management interoperability. An SMI-S provider is the software component that resides on a resource, such as a storage system, providing network management (over HTTP) by management clients, such as HP XP7 Command View Advanced Edition.
• Priority for acquiring the WWN, page 48 • About changing host settings and information, page 52 Methods for registering hosts There are a variety of methods to register one or more hosts including using its WWN, using host-installed agents, or agentless discovery.
Purpose Method Description To newly install HP XP7 Command View Advanced Edition to an existing environment that was configured with XP7 Remote Web Console. Scan a host. Use Host Scan when you want to newly install HP XP7 Command View Advanced Edition to an existing environment that was configured by using XP7 Remote Web Console.
Registering hosts by using Host Data Collector Use Host Data Collector to discover and register multiple hosts, virtualization servers, and virtual machines in a single task. Prerequisites • Gather the following information: • Host OS type • Host IP address (IPv4) NOTE: To detect multiple hosts at the same time, specify a subnet or a range of 256 or fewer IP addresses, or specify individual IP addresses.
2. On the Hosts tab, click Add Hosts. 3. In the Add Hosts dialog box, click Discover Hosts. If you are registering a virtualization server, select VMware from OS Type. 4. Specify the necessary items, select the Host Data Collector to be used, and then submit the task. The task is registered and listed on the Data Collection Tasks tab. 5. Verify task status on the Data Collection Tasks tab. Registered hosts can be viewed in the Resources list on the Navigation pane.
• The name of a host group should be the same as the actual host, and the WWN for that host is set for LUN security. • Only a single host can be related to each host group. Prerequisites • Install LUN Manager or LUN Management on the target storage system. 1. On the Administration tab, select Managed Resources. 2. On the Hosts tab, click Host Scan. 3. Confirm that your environment meets the recommended conditions, and then select storage systems on which to scan for hosts. 4. Click Submit.
4. 5. Review the target (surviving host) and source (host to be deleted) information. • If the target and source host information is correct, click Submit. • If the target or source host information must be changed, click Back. • To abandon the task, click Cancel. On the Resources tab, in the hosts tree, confirm the target host information and the source host removal. You can also confirm this on the Administration tab in the Hosts tree under Managed Resources.
A host group is configured on the storage system side, and the storage system is registered in Device Manager. After that, if a host is detected by Device Manager, a host group in the storage system that is selected at the time of detection of the host is registered in Device Manager. If the same WWN is registered to multiple hosts, only the WWN with the same name as the host that is already registered in Device Manager is added to the host.
To make changes to each item, use the method in the following table: Table 3 Updating host information using Host Data Collector Item Refresh Hosts Edit Hosts Host Name Y N OS Type N N Host IP Address N Y1 User ID/PW N Y Host Data Collector IP Address N Y2 Protocol N Y Port Type Y3 Y3 WWN Y3 Y3,4 WWN Nickname N5 N Legend: • Y : Can be edited or refreshed • N : Cannot be edited or refreshed Notes: 1. For virtualization servers, you can specify either IPv4 or IPv6. 2.
Changing settings for a manually registered host You can use Edit Hosts to update host information registered by specifying WWN, or registered by using the host detection function. 1. On the Administration tab, select Managed Resources. 2. On the Hosts tab, select the host to change, and click Edit Hosts. 3. Specify the required items, and then click OK. The host information is updated.
Item Refresh Hosts Edit Hosts Legend: • Y : Can be edited or refreshed • N : Cannot be edited or refreshed Notes: 1. When copy pairs are managed by a host where Device Manager agent is installed, you need to restart the Device Manager agent service after changing the host name. After the Device Manager agent service is restarted, the new host name is applied by updating the storage system. 2.
• Shred associated volumes. Format the volumes if shredding is unavailable. By automatically executing these options as an extension of removing a host, the process is simplified. NOTE: When removing storage resources related to a host, verify that there is not any related data remaining on the volumes. TIP: If you are removing a host that was registered using Device Manager agent, uninstall the Device Manager agent from the host, then remove the host using XP7 Command View AE.
3. In the Remove Hosts dialog box, select one or more options from the following: • Remove only selected hosts • Unallocate volumes and remove hosts When you unallocate the volumes that are used by the selected hosts and clean up the volumes, select from the following: • Delete associated host groups • Delete associated volumes • Shred associated volumes NOTE: Shred during off hours, such as overnight, so that the shredding process does not adversely affect system performance.
4 Setting up users and access control This module describes how to set up users and access control. Setting up users and access control After users are registered, you can limit the scope of allowed operations for each user by configuring access control settings for users and storage resources. To set access control you will need to create resource groups and user groups, then assign the resource groups and roles to the user groups.
Login with the System account to access user management in the Administration tab to create local XP7 Command View AE user accounts. While creating user accounts, you can list available applications (as installed on the management server) and set user permissions for those applications. Users must also be added to at least one (possibly more) resource groups to determine the storage they can access.
• Reporting user, and user group information in CSV format • Specifying security settings (such as locking an account) Resource groups and User groups: The resource group All Resources is a built-in group (created by default) and contains the built-in user groups called AdminGroup, ModifyGroup, PeerGroup, and ViewGroup. Adding a user to ViewGroup would allow a user to see all registered storage systems and related underlying detail such as parity groups.
1. On the Administration tab, click Users and Permissions. This will launch a user management window. 2. Click Users to display the current user list. 3. Click Add User and specify user profile information. 4. Click OK. The user list is re-displayed and will include the new user. TIP: To delete registered users, select the check boxes of the users to be deleted, and click Delete Users.
NOTE: When using a Windows computer for RAID Manager, you can also specify a backslash ( \ ) for both the User ID and password. If using external authentication servers such as LDAP (and others), note the following: • User IDs and passwords must be valid for the external authentication server and HP XP7 Command View Advanced Edition products. A password policy can be configured from the Administration tab to enforce stronger passwords.
Related topics • Changing your own password, page 64 Changing the password for a user account As user passwords expire or are compromised, they can be changed. 1. On the Administration tab, click Users and Permissions. This will launch a user management window. 2. Click Users, select the target user by clicking the User-ID link, and click Change Password. 3. Enter the new password and verify it. 4. Click OK. 5. Confirm that the user account can log in with the new password.
1. On the Administration tab, click Users and Permissions. This will launch a user management window. 2. Click Users, select the target user by clicking the User-ID link, and click Change Permission. 3. Edit the permissions and click OK. The user account is re-displayed, including granted permission. 4. Verify the correct user permissions are selected. The user permissions are changed.
1. From the Administration tab, select Users and Permissions. 2. Select Users folder, then select one or more users (using the checkbox) whose authentication method you want to change, or click Add User to create a new account. NOTE: When creating a new account, only the User ID is required for external authentication, and must match a user ID on the external authentication server. For a local (internal) account, a User ID and Password are both required.
• The XP7 Command View AE user group must exist on the external authentication (authorization) server. It is recommended that domain and group information, as required below, be acquired from the external authentication server administrator. 1. From the Administration tab, select Users and Permissions. 2. Click the Groups folder to display the Domain List. This is a list of external authentication servers listed by domain name, and host name or IP address.
• A resource group consists of storage system resources (storage systems, ports, LDEV IDs, and parity groups) • Assigned roles for resource groups provide either full, partial, or read-only access to resource group resources This creates an access control policy that allows secure data handling in multi-tenant environments and supports more efficient and secure operations.
Access control examples The following examples show how resource groups can control access in a HP P9500, HP XP7 system. One method for dividing resources would be by separating resources based on company location. For example, if you create resource groups based on location, the administrators in each location are limited to using only the resources that have been assigned to them, and are restricted from accessing the resources of other locations.
Related topics • About resource groups, page 70 • About user groups, page 73 • About access control, page 67 About resource groups Resources can be grouped by system resource types that include storage system, parity group, LDEV ID, and storage port. There are several types of resource groups: • All Resources is a resource group that is created during management server installation and includes all resources managed by XP7 Command View AE.
volumes in that LUSE or THP/Smart pool are also registered in the same resource group. For the HP XP7, when you register a part of a parity group that is part of a concatenated parity group to a resource group, other parity groups that are a part of the concatenated parity group will also be registered in the same resource group automatically. If the resource is in a HP P9500 or HP XP7 system, you can register it in only one user-defined resource group.
Resource groups, which are user defined, can be created for the HP P9500, HP XP7. 1. On the Administration tab, in the Administration pane, select Resource Groups. 2. Click Create Resource Group. 3. Enter a name and description, and select the storage system providing the resources. 4. Using the tabs, specify the parity groups, LDEVs, ports, or host groups (or a mix of resources) for the resource group. 5. Click Submit to register this as a task. 6.
• Assigning resource groups and roles to a user group, page 93 About user groups A user group consists of one or more users having the same permissions (role) for the same resources. An external authentication group can also be used as a user group. There are also built-in resource and user groups for administrative convenience. For a user group, one or more resource groups are added, and a role assigned for each resource group.
Some special cases apply: • If a user has the Storage Administrator (Provisioning), Modify, or higher roles for parity groups or the LDEV ID of a THP/Smart pool volume, and an unused LDEV ID is assigned to this user, they can create a volume. • If a user has the Storage Administrator (Provisioning), Modify, or higher roles for ports, and an unused Host Group ID is assigned to this user, they can allocate new volumes by using that Host Group ID.
Storage Manager CLI operations, permissions must be set for each user, and not by assigning roles to a user group. The table below describes the types of roles and the operations that can be performed when those roles are assigned. By specifying roles, resources that belong to a resource group for which a user has permission to reference or operate on are displayed. The user can perform operations or reference information for the displayed resources.
In addition to the table below, information is available about general XP7 Command View AE tasks and required roles and custom roles, see “Required roles and resource groups by function” on page 78. For a general overview of roles and custom roles, see “User group roles” on page 74. Note that to use custom roles, they must be assigned to resource groups with users.

On the Resources tab, select Storage Systems. 2.
About deleting unallocated volumes Volumes that are not allocated to any host can be deleted and their space added to the unused capacity of THP/Smart pools or parity groups. To completely and securely remove the data, shred the volume data before deleting the volume.
If the capacity of the LUSE volumes or basic volumes that have already been allocated to hosts becomes insufficient, you can increase capacity by adding unallocated volumes or creating LUSE volumes. LUSE volumes are created by using volumes that belong to the same resource group, have the same drive type, and are at the same RAID level. When using FMD/SSD flash drives in a storage system, you can still create a LUSE volume even if the drive types are different.
About releasing a LUSE volume To release a LUSE setting, the LUSE volume must first be unallocated from all hosts. Users can release a LUSE setting either by selecting it or using the Unallocating Volumes dialog box. NOTE: For HP XP7, you cannot release LUSE volumes.
Virtualizing external storage This module describes virtualizing external storage so that external volumes can be managed. About virtualizing and unvirtualizing volumes Virtualizing volumes is the process of mapping external storage system volumes to an internal storage system. Virtualized volumes allows for centralized management of volumes from multiple external storage systems, in addition to the volumes from the single storage system being managed with HP XP7 Command View Advanced Edition.
TIP: When an HP XP7 is used, in the window that appears by clicking the System GUI link, you can reconnect or disconnect external storage systems, reconnect or disconnect external volumes, edit path groups (such as changing the priority), and perform un-virtualization of external volumes.

About virtualizing storage capacity Thin Provisioning (THP) provides virtual volumes to a host and allocates the actual capacity from a THP pool when a host makes a write request. By using THP pools, you can allocate more capacity to a host than that allowed by the actual physical configuration of the storage system. THP pools provide the following advantages: • You can reduce system setup and operational costs. • You can use resources more efficiently. • You can distribute workload equally among volumes.

6 Optimizing storage performance This module describes how to improve your storage. About optimizing storage HP XP7 Command View Advanced Edition allows you to manage storage by allocating volumes, expanding tiers and THP/Smart pools, and performing migration, based on information acquired from checking summaries, alerts, performance statistics, and the operating status of storage resources. Storage utilization can also be improved with effective management of HBA and cache (CLPRs) resources.
• When using Smart pools, important data is allocated to the lower hardware tier because it has fewer I/O accesses. To prevent unwanted relocations, set a specific hardware tier for the Smart pool by configuring tiering (Tier 1, Tier 2, and Tier 3). • When using Smart pools, use the flexibility of tiering to spread the data in a host volume across multiple layers of parity groups (high-speed, next highest speed, and low-speed) that are contained in a pool structured for this purpose.
Adding an HBA Add an HBA to improve performance and throughput requirements. When adding an HBA, specify the WWN of the new HBA and then select a WWN of an existing HBA from which to model paths. Prerequisites • Identify the new WWN for the HBA that is being added • Identify the WWN from which to model paths • Verify that the new HBA is physically connected 1. On the Resources tab, select Hosts. 2. After selecting the target operating system, select the target host row and click More Actions > Add HBAs.
Managing cache logical partitions This module describes how to manage cache logical partitions (CLPR), including managing the assignment of resources to the CLPR. Creating a CLPR You can create partitioned cache as a means of providing predictable performance levels for server applications, and providing memory protection. CAUTION: Creating CLPRs can significantly degrade host performance and should be performed during the initial installation and setup of the storage system or during a maintenance window.
7. In Number of Resident Extents, enter the number of resident cache. The default is 0, and you can specify 0 to 16384. The maximum available capacity (by subtracting the total usage capacity of other CLPRs from the total capacity of the storage system) is displayed as the upper limit value. 8. Click Add. The created CLPR is added to the Selected CLPRs table. To delete a CLPR from the Selected CLPRs table, select the CLPR and click Remove.
4. In CU, select the CU to which the resource is assigned. 5. In Available Parity Groups or Available Virtual Volumes, select the resource that you want to migrate, and then click Set>. This adds the selected resource to the CLPR table. To check the information of the CLPR, select the CLPR and click Detail to open the CLPR Properties window. 6. When you are done adding resources to migrate, click Finish. 7. On the Confirm window, check the settings carefully. 8. Click Finish. 9.

You can use up to 16 alphanumeric characters but you cannot specify CLPR names that are already reserved. 2. In Total Cache Size, edit the CLPR cache capacity as needed. The minimum cache size is 8 GB, and the size can be changed in increments of 4 GB.
Deleting a CLPR You can only delete CLPRs that you created. CLPR0 cannot be deleted. CAUTION: The delete CLPR operation deletes all resources and data in the CLPR. Before deleting a CLPR, migrate all resources that you want to keep (for example, parity groups) to another CLPR that will not be deleted. For details, see the “Migrating resources to and from a CLPR” on page 177. 1. On the Resources tab, expand the Storage Systems tree, and select the target storage system. 2.
From the Mobility tab, data placement can be optimized from either the application (logical group) perspective or from the THP/Smart pool perspective. To respond to requests from host or application administrators, or to confirm whether Smart pools and storage resources are being used according to the needs of each application, check the balance between the performance and the configuration ratio of logical groups.
By creating tiers of volumes or THP/Smart pools based on use or performance, you can migrate data to volumes or THP/Smart pools that match the relevant conditions simply by specifying a tier as the migration target.
• Top 10: Pools with the Highest Used % Check on a regular basis for THP/Smart pools with a high capacity usage rate to determine THP/ Smart pools that need pool expansion or data migration. • Top 10: Pools with the Highest Subscription Check on a regular basis for THP/Smart pools with a high reservation rate to determine THP/ Smart pools that need pool expansion or data migration on a regular basis.
Check the ratio of actual I/O operations to the calculated maximum number of I/O operations for each hardware tier. Based on this information, you can determine the hardware tiers whose performance is in a saturated state that then require an optimization operation (such as editing the tiering policy or data migration). • Top 10: Volumes Sharing Tier Capacity Check the usage ranking of volumes that have the largest use capacity in each hardware tier.
Optimizing data placement in a THP/Smart pool Data placement can be optimized in a THP/Smart pool. Prerequisites • A Tiered Storage Manager license must be registered. • An HP XP7 Performance Advisor license must be registered (when referencing performance information). • Ensure that Smart pools are being monitored (when referencing Performance Utilization, IOPS for a hardware tier, or View Tier Properties). 1. From the tree view of the Mobility tab, select THP Pools. 2.
For example, you can migrate data when your volume performance decreases or your environment changes. When relocating data based on the results of performance monitoring for volumes being used by servers and applications, or when migrating data from an old storage system to a newly set-up storage system, the data in multiple volumes can be migrated to other volumes or THP/Smart pools. The source volume can be selected by host or by logical group.
For details on the properties file, refer to the HP XP7 Command View Advanced Edition Administrator Guide. To avoid insufficient memory, we recommend that you use the default. The maximum number of volumes that can be displayed as migration target candidates is 2,000 volumes. Exceeding this value will produce an error. The maximum number of volumes that can be displayed as migration source candidates is 500 volumes. Exceeding this value will produce an error.
migration source volume is re-created. The remaining capacity can be reused. If you set a value for the property migration.plan.candidateCapacityGroupDisplayMaxCount in the migration.properties file, you can specify how many volumes with a larger capacity than the migration source volume to display, in addition to the volumes with the same capacity as the migration source volume.

7 Grouping resources This module describes how to group logical groups and storage tiers (resources). Managing logical groups This module describes how to manage the two supported logical group types: public and private. Public and private logical groups are listed in the navigation pane (Resources > Logical Groups) under the Public Logical Groups root folder and the Private Logical Groups root folder, respectively.
Private logical groups Top-level folder that corresponds to each user group. • Private logical group folder that contains groups of hosts and volumes that are grouped by business function, geographic, or other organizational divisions. • Logical groups of hosts. • Logical groups of volumes. The following figure illustrates the structure of logical groups. The following descriptions and figures show key differences between public logical groups and private logical groups.
• In private logical groups, only users that belong to specific user groups can access the private logical groups that are associated with the user groups to which they belong. The Private Logical Groups root folder can include separate private logical groups thereby maintaining a logical separation between business organizations or tenants, to provide for the secure sharing of resources.
>public-logical-group Each public logical group can be a logical group of hosts, a logical group of volumes, or a logical group folder that contains both hosts and volumes. All users can access these public logical groups. Private Logical Group Root folder for private logical groups > user-group-name top-level folder A top-level folder for each user group. This folder is created by XP7 Command View AE under the Private Logical Groups folder and can be used as a work folder for a user group.
Creating logical groups XP7 Command View AE supports two types of logical groups: Public Logical Groups and Private Logical Groups. Prerequisites • Verify that any host to be assigned to a logical group is a normal host, a virtualization server, or a virtual machine registered as a host. Observe the following restrictions: • Mainframe volumes (MF-Vols) cannot be assigned to a logical group. • Child groups cannot be created below host or volume groups. Child groups can be created only below folders. 1.
TIP: To delete logical groups, select the logical groups to be deleted, click Delete Logical Groups, and click OK. Related topics • About logical groups, page 203 • Editing logical groups, page 208 Viewing logical group reports You can view summary reports for specified logical groups. 1. On the Resources tab, click Logical Groups. 2. Expand the tree and select the target logical group.
Performing operations from a logical group You can perform tasks on storage systems by starting from a logical group. 1. On the Resources tab, select Logical Groups, and select either Public Logical Groups or Private Logical Groups. 2. Expand the appropriate logical groups tree and select the target logical group. 3. Select a host or volume. 4.
About tier-based storage management In HP XP7 Command View Advanced Edition, you must have a Tiered Storage Manager license to perform tier-based storage management operations. In a tier-based storage management system, storage system resources are grouped and managed in tiers. Tiers can be created for volumes or for Thin Provisioning (THP/Smart) pools to allow high-capacity resources to be centrally managed. Tiers allow you to allocate data according to its purpose.
1. On the Resources tab, select Tiers. 2. Select the storage system for which to create a tier. 3. Click Create Tier. 4. Specify the appropriate information. 5. Click OK. The tier is created and added to the storage system. TIP: To remove tiers, select the tiers to be deleted, and click Delete Tier.

Managing resource labels This module describes how to manage resource labels. About managing resource labels User defined resource labels can be assigned to volumes and THP/Smart pools. Specifically, resource labels can be volume labels, or THP/Smart pool names.
TIP: You can apply any current label to the storage system by specifying the following settings: • For volume labels, select Reflect current labels to the storage systems. • For THP/Smart pool names, select Reflect this pool name to the storage system. Related topics • Editing resource labels, page 214 • Searching resource labels, page 214 • Importing storage system resource labels, page 215 Editing resource labels You can create or edit resource labels for volumes or THP/Smart pool names. 1.
1. Locate volumes or THP/Smart pools by using one of the following methods: 2. • Using the search box, enter a volume label or THP/Smart pool name, and perform a search. You can use Search Keyword for to specify the resources you want to search, for example Volumes. • From the search box, you can also search volume labels by using More Searches, selecting Volume, and selecting the category Label from the Advanced tab.
About managing WWNs by using nicknames Each host bus adapter (HBA) has a unique World Wide Name (WWN) identifier that consists of a 64-bit physical address. The purpose of specifying WWN nicknames is to easily identify accessible HBAs that are registered in a host group. If one HBA WWN belongs to multiple host groups, you can set a nickname in the WWN information that is defined for each host group.
TIP: If a nickname is set to a WWN by using a storage system management tool, such as Remote Web Console, you can view the latest WWN nickname by refreshing the storage system information. Also, if there are multiple WWN nicknames set to the host groups on the storage system, only one WWN nickname for the port on the host is selected and displayed automatically.
8. Click Submit. If the task is scheduled to run immediately, the process begins. 9. (Optional) Check the progress and result of the task on the Tasks & Alerts tab. Click the task name to view details of the task. The WWN nickname edits are applied to the WWNs registered in the host group.

Keyword search To perform a keyword search, locate the Search box on the upper right side of the GUI. The search box is always visible. 1. Enter a full or partial text string in the Search box. A partial string will generally produce more search results. 2. By default, all resources are searched when you press Enter. You can narrow the scope of your search using the down arrow, selecting Search Keyword for, and selecting a specific resource to search on. This executes the search and displays results.
4. The Basic and Advanced tabs provide further refinements for your search. The selected storage resource (volumes, parity groups, etc.) affects the search criteria available under the Basic and Advanced tabs. This can be seen by changing the selected storage resource and reviewing available options. 5. To run your search, click Search.
• A logical operator drop down (unlabeled) is provided for each category in your search. Values are text or symbols, and can include: in, not in, is between, is, is not, starts with, contains, =, >, >=, <, <=, and<>. • The Value field provides either a drop-down list of values, or prompts you to enter data (names or numbers). When entering data, a valid entry displays a blue border, an invalid entry (format, spacing) displays a red border.
Storage System For a Volume search, using Attribute, you can specify Storage System Vendor, or Storage System Model (useful if you have multiple storage systems of the same type). The Value drop down provides available vendors or models. You can invert the search results using the is/is not operator. The +/- buttons allow the addition or removal of additional search conditions. When switching to other supported search types, investigate the Attribute and Value fields to see what is available.
Subscription For a THP/Smart Pool search, using Attribute you can specify Subscription (used space), Subscription Warning (warning threshold for volume creation), or Subscription Limit (threshold where volume creation is not allowed), and enter a number representing a percentage (you do not need to enter the % symbol). For example, you can find THP/Smart Pools with a subscription limit equal to 120%, or warning thresholds equal to or greater than 70%.

Monitoring Continuous Access Journal performance Prerequisites Make sure that the requirements described in “Prerequisites for analyzing Continuous Access Journal performance” on page 244 are satisfied before using the Replication tab. You can monitor Continuous Access Journal performance (C/T delta) from the Replication tab. If you see problems, you can then perform an analysis to discover the root cause.
3. If the C/T delta threshold for a copy group is exceeded, you can perform an analysis: • In advanced mode, you can perform the analysis yourself by viewing a series of graphs to determine the root cause of the problem. See “Analyzing Continuous Access Journal performance in advanced mode” on page 248 for more information. • In wizard mode, you are guided through a selection of key metrics and presented with a summary of possible causes and solutions.
Metrics for Continuous Access Journal performance analysis The following table lists the metrics used to analyze Continuous Access Journal performance. Table 21 Continuous Access Journal performance metrics Metric Description Threshold Value / Notes Cache Write Pending Rate Write pending rate for the cache used by the MPB. Caution: > 30% Processor Busy Rate Operating rate of the MPB. Caution: > 40% Journal (JNL) Usage Rate Usage rate for the journal.
5. On the displayed pages, examine each metric and use the checkbox to mark any resources that exceed the threshold. (You can select Mark resources that exceed pre-set threshold to select them all.) Click Next to proceed. 6. The Results Report page includes the detected issues and the possible causes and solutions based on your selections. Click the Show Detail link to display the resources and the graphed data.
TIP: The list of volumes also includes any Cnt Ac-S copy groups that use the same remote path as the target. • You can also annotate a graph with memos, text windows that allow you to take notes. • Click Add Memo to start a new note. You can also add a note by double-clicking within a graph. • As with any window, you can move, minimize, or delete it using the controls in the title bar. TIP: By default, Replication Manager polls information sources for copy pair status every 5 minutes.
About refreshing Replication tab data By default, Replication Manager polls information sources for copy pair status every 5 minutes. (This setting is part of the Replication Manager GUI, not the Replication tab.) If you have increased this polling setting (refresh value) to be longer than the data interval in the Replication tab, the plot in the graph is updated less often (regardless of the data interval setting).

A Managing virtual storage machines This module describes specific functionality available for managing virtual storage machines. About managing resources by using virtual storage machines A virtual storage machine is a virtual storage system (a group of resources) that you create in an HP XP7 Storage, and then specify virtual information for it, such as a virtual model and virtual serial number.
TIP: You create and edit resource groups on virtual storage machines by using the CLI. For more information about CLI commands, see the HP XP7 Command View Advanced Edition CLI Reference Guide. The following figure shows an example configuration of a virtual storage machine. In the example configuration, the virtual storage machine is created using the model type and serial number of the HP XP7.
During the three stages of data migration, accessing the information changes from using physical to virtual information. • Before data migration (using physical information) Before data migration, a host uses physical information to access the migration-source resources. • During data migration The path from the host to the storage system is changed from the migration source to the migration destination.
Prerequisites Gather the following information: • Serial number, if specifying a storage system that is not registered with XP7 Command View AE. 1. On the Administration tab, select Virtual Storage Machine. 2. From the application pane, click Create Virtual Storage Machine. 3. Enter the name for the virtual storage machine. 4. Specify the model and serial number by using one of the following: 5. • Click Select a storage system already registered on CVAE from list and select from the list.
Allocating volumes to hosts by using virtual storage machine resources The storage administrator can allocate volumes to hosts by using the resources of a virtual storage machine. The volumes of the default virtual storage machine can also be allocated. The default virtual storage machine is created in XP7 (by default). Prerequisites • Identify the name of the target host.
16. On the Resources tab, select hosts to verify that volumes have been allocated. When a default virtual storage machine volume is allocated, the volume is registered to the virtual storage machine to which the host groups belong and the new virtual information is configured. TIP: When you are canceling volume allocation, you can delete the virtual information and move the volume to the default virtual storage machine.
The selected virtual storage machine is deleted.
Managing virtual storage machines
B Managing storage resources that have virtual IDs This module describes specific functionality available for virtualized volume resources for which virtual IDs are assigned. About managing storage resources that have virtual IDs When replacing an old storage system with a HP XP7 or HP P9500, you can use virtual IDs to migrate a resource without stopping the resource. Virtual IDs provide information about the old storage system, and are configured on the migration-destination resource.
from the migration-source resource. On the migration-destination storage system, while data migration is in progress, operations cannot be performed on the resource by using Device Manager. • After data migration (operation using virtual IDs) After all of the target resources are migrated, operations can be performed on a resource by using Device Manager. After data migration, a host uses virtual IDs to access resources and perform operations on the migration-destination storage system.
Displaying virtual ID information You can display virtual ID information in the volume list to identify the target resource from the virtual ID information. Virtual ID information of resources can be displayed per host, storage system, or logical group. 1. On the Resources tab, select Hosts, Storage Systems, or Logical Groups. 2. Expand the tree and select the target resource to display the volume list. 3. Click the Column Settings button. 4.
4. Allocate volumes with existing virtual ID information, or volumes requiring virtual ID assignments as follows: 1. To allocate volumes that belong to resource groups being used for a data migration that uses virtual IDs, reference the virtual ID information and manually select volumes, and then click Show Plan to register this as a task. 2.
