Overview of HP StorageWorks P9000 Command View Advanced Edition Suite
2 Discovering, registering, and adding management targets Managing storage resources requires them to be registered in HP StorageWorks P9000 Command View Advanced Edition Suite software. Registration automatically occurs after discovery. Registering storage systems Before you can manage a storage system's resources, you must first register the storage system.
Prerequisites for registering a storage system Before registering a storage system, you need to collect system-related information and complete a number of prerequisite tasks. Collect and confirm the following storage system information: • • • • Storage system type. Storage system IP address (IPv4 or IPv6) or host name (alias name). User name and password for the storage system management tool, such as Remote Web Console.
3. Specify the storage system type and provide the following information: • An IP address (or hostname). • Authentication information (username and password) for most supported storage systems. • For SMI-S enabled storage systems, provide the SMI-S provider IP address, authentication information, protocol information (secure, not secure), and possibly a non-default port number.
About acquiring the most recent storage system information To get the most current information about a target storage system, manually refresh the system to display it.
NOTE: Label information for volumes and THP/Smart pools is not refreshed. To apply existing label information from a storage system to Command View AE Suite, click Refresh Labels. Related topics • About acquiring the most recent storage system information, page 30 Operations available to SMI-S enabled storage systems Discovering and registering storage systems that are managed by an SMI-S provider (SMI-S enabled storage systems) enable you to perform certain tasks.
• Virtual machines (a machine that is created on the virtualization server and uses virtualization software) Depending on the purpose, there are multiple methods for discovering and adding hosts, including manually, by using Host Data Collector (agentless discovery), or by using a Device Manager agent. For host prerequisites and environment settings, see the HP P9000 Command View Advanced Edition Suite Software Administrator Guide.
Purpose To know the usage status of storage resources for the virtualization servers, or the correspondence with the virtual machines. Method Use Host Data Collector or Use vMA (vSphere Management Assistant).

• • • • • Delete associated host groups Release LUSE volumes Delete virtual LDEV ID. This applies when managing resources that have virtual IDs set. Delete associated volumes 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.
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.
You can also add or refresh storage systems and hosts on the Resources tab, but not edit or remove them. The process for removing hosts cannot be a data collection task because this involves storage resource operations such as releasing volume allocation and deleting volumes. You manage the process of removing hosts using the Tasks & Alerts tab.
The status of the restarted data collection task no longer appears as Failed in the list of tasks.
3 Managing storage resources in a SAN environment This module describes managing storage resources such as THP/Smart pools and volumes in a Storage Area Network (SAN). Creating and deleting volumes This module describes how to create volumes (including LUSE volumes), and delete unallocated volumes. About creating volumes You create volumes, then allocate them to a host. You create volumes by using the available space in a THP/Smart pool or parity group.
1. On the Resources tab you can create volumes from several locations: • • • • 2. From General Tasks, select Create Volumes. Select the storage system, click Actions, and select Create Volumes. Select the storage system, list existing parity groups, and click Create Volumes. Select the storage system, list existing THP/Smart pools, and click the Create Volumes button or select Create Volumes from Actions. In the create volumes dialog box, configure volumes and their characteristics. 3.
Field Subfield Description Storage System - This field will either display the selected storage system name, or prompt the user to select the storage system from a list. - Select the volume type to create. For example Basic Volume, Thin Provisioning or Smart Pool. The displayed volume types are determined by your selected storage system. If you do not see an expected volume type, check that you have selected the correct storage system.
About shredding volume data Before deleting a volume that you no longer need, completely remove the data from the volume to avoid unauthorized use of information. The data can be removed by shredding or reformatting the volume. Volume data is shredded by overwriting it repeatedly with dummy data, which securely destroys the original data. Some volumes, such as basic volumes and THP/Smart volumes that are allocated to hosts or used for replication, cannot be shredded.

If the task is scheduled to run immediately, the process begins. 8. You can check the progress and result of the task on the Tasks & Alerts tab.
6. Click Submit, and confirm task completion. When the task completes, deleted volumes no longer appear in the Open-Unallocated or THP volume list. Related topics • Unallocating volumes from hosts, page 104 • About deleting unallocated volumes, page 53 • Shredding volume data, page 52 About creating a LUSE volume A LUSE volume is collection of two or more basic volumes that have been grouped together to increase available capacity.
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.
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 StorageWorks P9000 Command View Advanced Edition Suite.
Virtualizing volumes of a registered storage system Choose from a list of existing unallocated volumes in the external storage system to be virtualized. Or specify the number of volumes and volume capacity to search for volumes that meet the criteria. Prerequisites • The internal and external storage systems are registered in HP StorageWorks P9000 Command View Advanced Edition Suite. • The external storage system is connected to one or more external ports of the internal storage system.
When the task completes, the existing volumes are allocated to the internal storage system and virtualized. Related topics • About virtualizing and unvirtualizing volumes, page 56 • Virtualize Volumes dialog box, page 60 • Unvirtualizing volumes, page 59 Discovering and virtualizing volumes of an unregistered storage system Use the port scan and volume discovery functionality to detect external storage system volumes allocated to the external port and then virtualize the available volumes.
9. Review the list of volumes to be virtualized and click OK. 10. (Optional) Click Internal Volume Configuration to configure the options for the volume to be virtualized, such as the parity group ID, CLPR, inflow control, LDEV labels, and LDEV IDs. 11. Click Show Plan and confirm that the information in the plan summary is correct. If changes are required, click Back. 12. (Optional) Update the task name and provide a description. 13. (Optional) Expand Schedule to specify the task schedule.
5. (Optional) Click Advanced Options to configure deleting the host group, releasing LUSE volumes, or deleting volumes. NOTE: If the selected external storage system is not a registered storage system, you can unmap volumes only. 6. Click Show Plan and confirm that the information in the plan summary is correct. If changes are required, click Back. 7. (Optional) Update the task name and provide a description. 8. (Optional) Expand Schedule to specify the task schedule.
As you enter information in a dialog box, if the information is incorrect, errors that include a description of the problem appear at the top of the box. Table 6 Virtualize Volumes dialog box Field Subfield Description External storage system is displayed if you selected a registered storage system and launched the dialog box. If you did not, select an external storage system from the list.
Field Subfield Description Existing drive type is displayed based on the selected storage system. If multiple drive types are displayed, accept the default or select from the drive type list: • Any • FC - Fibre channel • SAS - Serial Attached SCSI Drive type - • SATA - Serial ATA • FMD - Flash module drive • SSD - Solid state drive • SAS (SED) - SAS self-encrypting drive Any is displayed when you can select more than two drive types. Changing drive type can change the parity group.
Field Subfield Description Int. Storage System The connected internal storage system. Int. Storage Port The port of the connected internal storage system. This port is a part of the internal storage and used to connect to the external storage. Edit external paths from a table or from a graph. To create an external path, select an external storage port and an internal storage port. To delete an external path, select the path that you want to delete.
Field Parity Group Subfield Description - Assign internal volumes to a parity group by entering a Start from number. For Device Manager, when you specify the first number (1-16384), the second number is automatically assigned. The format for specifying external parity groups is, for example, "E1" or "E16384". CLPR - From the list, select the cache logical partition resource (CLPR) value for the internal volumes.
About virtualizing storage capacity HP StorageWorks P9000 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.
• • • • • • Expanding THP/Smart pools, page 73 Shrinking a THP/Smart pool, page 75 Modifying THP/Smart pool settings, page 75 Deleting THP/Smart pools, page 75 Expanding THP/Smart volumes, page 76 Reclaiming zero pages, page 77 Creating a THP/Smart pool You can create an THP or Smart pool, which provides more efficient use of physical storage for virtual volumes that are allocated to hosts from the THP/Smart pool. Prerequisites • Register the target storage system.
4. To configure an Smart pool, in Pool Type, select Smart and in Additional Parity Groups, choose Standard or Mixed mode. For Standard mode (single drive type/speed, chip type, RAID level, and volume location in a single tier): • Click + to add a new tier. • In the Add New Tier dialog box, select a volume to configure Tier 1, and click Select. The Tier Configuration table in Pool Summary is updated. • Click Add Parity Groups, select the parity group, click Add to Pool, and click Close.
Created pools are added to the target storage system THP Pools list. Related topics • • • • • About virtualizing storage capacity, page 65 Create Pool dialog box, page 68 Verifying THP/Smart pool information, page 72 Modifying THP/Smart pool settings, page 75 Deleting THP/Smart pools, page 75 Create Pool dialog box Pools can be created for storage systems that support THP. In addition, Smart pools of differing performance levels can be used to improve application performance.
Field Subfield Description Pool Summary information is updated as parity groups are selected (number of parity groups, THP pool capacity, used % (for thresholds 1 and 2), and subscription % (that trigger subscription warnings and limits). When pools are configured, use Advanced Options to set the Used Thresholds 1 and 2, and the Subscription thresholds for warnings and limits.
Field Subfield Description (Information in the Additional Parity Groups table differs depending on the selected pool type.) For an THP pool, this table displays parity group, drive type, drive speed, chip type, RAID level, total capacity, unallocated capacity, free capacity, number of available volumes, external storage system, and external storage model.
Field Subfield Description Pool ID Accept the default pool ID number, or choose from the options in the menu. Use Show Pool ID Usage to display pool ID number and names that are currently in use. Used Threshold 1 Set the level of physical capacity usage as a percentage (1-100 range) of the physical THP/Smart pool capacity. When this threshold is exceeded, it generates an alert, an email, or both. Alerts display on the Dashboard and the Tasks & Alerts tab.
Field Subfield Description Monitoring mode Periodic monitoring mode uses performance data from the last monitoring cycle (see Cycle time). Tier relocation responds immediately to workload changes. This mode is a more aggressive tier relocation monitoring mode. Periodic Buffer Space for New page assignment Sets the buffer space used for new page assignments to Smart tiers (using the default values is recommended).
Related topics • About virtualizing storage capacity, page 65 • Creating a THP/Smart pool, page 66 Expanding THP/Smart pools Pool capacity can be increased by expanding THP/Smart pools or by converting THP pools into Smart pools. Expand a THP/Smart pool by adding volumes to it. Expand an existing THP pool by converting it into an Smart pool, which changes the pool type and allows you to configure tiers that support a mix of drive types and RAID levels. Prerequisites • Register the storage system.
3. To expand an Smart pool, in Additional Parity Groups, choose Standard or Mixed mode. For Standard mode (single drive type/speed, chip type, RAID level, and volume location in a single tier): • Tier 1 is the default, click Add Parity Groups, select the parity group, click Add to Pool, and click Close. Select an available parity group that best meets your performance or capacity needs (Tier 1 for best performance, Tier 2 for next best performance, and Tier 3 for capacity).
• Shrinking a THP/Smart pool, page 75 • Expanding THP/Smart volumes, page 76 • Reclaiming zero pages, page 77 Shrinking a THP/Smart pool Shrinking a THP/Smart pool allows the recovery of excess free capacity. 1.

You can discover and register not only at the logical group level, but also at the host or Smart volume level. NOTE: If you want to register by host, you can start this process by selecting the Resources tab. 2. Expand the tree to select the target logical group from Public Logical Groups or Private Logical Groups. 3.
TIP: The capacity ratio of Tier 1 might exceed the value specified for the maximum allocation threshold if a data placement profile and a tiering policy are being used concurrently. Related topics • About virtualizing storage tiers, page 77 Customizing a tiering policy for Smart volumes You can set the value for the allocation threshold of a hardware tier. When a tiering policy is specified for Smart volumes, make sure changing the definition will not cause a problem.
• A task to create, update, apply, or release a data placement profile or to search for or repair an inconsistency in a data placement profile takes time to complete after it is executed. This time might affect other operations, so make a plan based on the displayed time estimate. Keep in mind that the larger the number of target volumes, the more likely that the estimated time and the actual execution time will differ greatly. You can also stop tasks that are being executed, and then restart them.
TIP: If linked to HP StorageWorks P9000 Performance Advisor software, you can view performance trend charts for the volumes in the logical group from the Manage Data Placement Profiles dialog box. For details on the linking method, see the HP P9000 Command View Advanced Edition Suite Software Administrator Guide. 1.

4 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 Command View AE Suite under the Private Logical Groups folder and can be used as a work folder for a user group.
Creating logical groups Command View AE Suite 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.

• The Command View AE Suite 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 user group is a group of users with the same user permissions and range of access. Externally authenticated groups can also be used as user groups. When you assign resource groups and roles (collections of user permissions, such as Modify or View) to a user group, resources can be controlled for the users in that group. Resource groups can be created in this configuration only when the storage system is HP P9500 .
It is also possible to share physical resources (such as parity groups or storage ports) among departments, and divide only logical resources (such as LDEV IDs or host group numbers) by department. For example, you can assign resource groups that contain shared physical resources to all departments, and then assign individual resource groups that contain specific logical resources to the appropriate departments.
• Creating resource groups, page 195 • Editing a resource group, page 195 • User permissions in Legacy mode, page 215 Resource groups Resources can be grouped by system resource types that include storage system, parity group, LDEV ID, and storage port.

A Managing storage resources that have virtual IDs This appendix 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 HP P9500, you can use virtual IDs to migrate a resource without stopping the resource. Virtual IDs are information about the old storage system, and are set on the migration-destination resource.
indicates that data migration in progress is valid, 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. A host uses virtual IDs to perform operations on the resource on the migrationdestination storage system. Items such as virtual LDEV ID and virtual ports can be checked as virtual ID information.
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.
B Operations in Legacy mode This appendix describes data migration using migration groups that were supported in prior HP StorageWorks P9000 Command View Advanced Edition Suite versions. About Legacy mode Legacy mode is an option for performing data migration by using migration groups that were supported in versions earlier than v7.1.1. To use legacy mode, set the client.migration.use.legacymode property value in the client.properties file of Device Manager. For details about the client.migration.use.
NOTE: Peer role cannot be assigned in combination with any user permission level other than User Management. Additionally, you can assign the following Tiered Storage Manager permissions: • Admin: A user with Admin permission can only view Tiered Storage Manager resources and tasks. • Modify: A user with Modify permission can perform volume migrations and all operations in the Tiers tree on the Resources tab.
For details on the properties file, refer to the HP P9000 Command View Advanced Edition Suite Software Administrator Guide. To avoid insufficient memory, we recommend that you use the default. The values below ensure the operation of Tiered Storage Manager in Legacy mode. Performance might slow down or memory might become insufficient if a value exceeds the maximum value.
All volumes for which data migration is to be performed in Legacy mode must meet the conditions below: • Migration-source and migration-target volumes exist within one of the following storage systems (chassis): • HP P9500 • XP24000/XP20000 • XP12000/XP10000/SVS200 • The emulation type, number of blocks, and size are the same for the source and target migration volumes.

5. Specify any necessary items in the Rule tab and in the Notification tab. When the parity group selection rule is set, a candidate volume that is appropriate as a migration target will be selected depending on the application that is being used or the usage rate of the parity group. Specifically: • Balance Capacity: System attempts to select a migration target candidate so that the remaining capacity of the targeted parity group is equalized with other parity groups.
