The WWN of host group BBB is already registered to host AAA, and host BBB cannot be registered in Device Manager. Host CCC, which has the same name as host group CCC, is added to Device Manager, and the WWN of 33.33.33.33.33.33.33.33 for host group CCC is registered to host CCC.
Registering hosts using merge hosts You can register hosts using Merge Hosts to manage and monitor the host. Conditions for a target host: • It is not a mainframe host • It is not a virtual host • At least one WWN must be registered for the destination host Items to check beforehand: • Source host name 1. From the Administration tab, select Managed Resources. 2. From the Hosts tab, select the line for the target host, and then click Merge Hosts. 3. Specify the source host, and then merge the hosts.
To change authentication information about a registered IP address or user account, edit the IP address or user account by using the Edit Hosts dialog box, and then execute a refresh operation.
2. 3. On the Hosts tab, select the host to change, and click Edit Hosts. Specify the required items, and then execute the process. The host list is updated. Updating host information registered by using vMA Use Refresh Hosts to update host information registered by using vMA. To change authentication information about a registered IP address or user account, edit the IP address or user account by using the Edit Hosts dialog box, and then execute a refresh operation.
3. Execute the processing. The task is registered to Data Collection Tasks tab. If you changed settings in the Edit Hosts dialog box, after the task has completed successfully, execute a refresh operation using Refresh Hosts. The host list is updated. Changing settings for a host registered by using Device Manager agent When the Device Manager agent is being used, host information is automatically sent from the Device Manager agent periodically. Execute Refresh Hosts as necessary.
The host list is updated. NOTE: If a host name is changed, both of the host names (before and the after change) might be displayed on the Resource tab. In this case, delete the host before making the change. When copy pairs are managed by the host where Device Manager agent is installed, in addition to deleting the host, the storage system also needs to be updated.

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.
• Specify when the task should execute. 4. 5. Click Submit. When the task completes, verify that the volumes appear in the Open-Unallocated volume list on the Resources tab. 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.
2. 3. 4. 5. 6. 7. Expand the tree and select the target OS. Select the target host from the list of hosts, and from the displayed list of volumes select the LUSE volume or basic volume, and then click the Create LUSE Volume button. Click the Add Volumes button. Select a volume(s) to be added, and then create a plan. If there is no problem, execute the plan. View the list of tasks to make sure that all tasks are complete.
To externally connect an SMI-S Enabled storage system, execute it from CLI. For details about how to use CLI to externally connect a storage system and disconnect an external connection, see the HP P9000 Command View Advanced Edition Suite Software CLI Reference Guide. Virtualizing volumes Volume virtualization provides the capability to optimize storage services to applications by facilitating movement of data between tiers and migration of data between different generations of technology.
You can create virtual volumes (THP/Smart volumes) from physical volumes that are grouped into THP/Smart pools. You can then allocate those virtual volumes to hosts. In the illustration below, note that the volumes used to create the THP/Smart pool are called THP/ Smart pool volumes. The THP/Smart pool is then used to provide capacity as needed to allocated THP/Smart volumes. THP/Smart pools are created by Device Manager, which automatically selects volumes based on user-specified conditions.
The Create Pool dialog box opens. 3. 4. 5. Specify the pool name and other information. If you want to manually monitor or relocate Smart pools, set Tier Management in Smart Options to Manual. Click Show Plan to review the plan and specify additional information, as appropriate: • Verify the information that is displayed. • Enter a name in Task Name. • Specify when the task should execute. 6. Click Submit. The plan is registered as a task. 7.

You can select a specific tier policy for the volume to be allocated, or select All. Note: This field is not the same field as the Volume Selection field above when Volume Type is set to Smart Pool.
Fields and Dropdowns Creating Volume Settings Subfields Format Type Descriptions Creating Volume Settings, and related fields, is only displayed when entered volume criteria require a new volume to be created. See Volume Capacity field above for an example. This field displays formatting methods available for the volume to be created, as available for basic volumes on the specified storage system. For example, you might see options for a quick or basic format.
Fields and Dropdowns Subfields Descriptions Name For hosts in a host group, host group information is displayed. For hosts not in a host group, a host group can be created. Enter a name if a host group is needed. Host Group Settings in Detail This button is used to display a list of host groups to be used during volume allocation, or which were previously set during prior volume allocations. Host mode Select the host mode that supports the host type for which you are allocating volumes.
Refreshing host information, including host names and WWNs, does not update storage system WWN nicknames in HP StorageWorks P9000 Command View Advanced Edition Suite. • If several WWN nicknames (for example, as set on different storage systems) exist for a host HBA, only one of the nicknames is displayed for that HBA.
About unallocating volumes You can unallocate volumes from clusters, or hosts. Unallocated volumes can be: • Re-allocated (with existing data) to a cluster, or host that can recognize the existing data (file system). • Used for other storage requirements. Unallocating a volume deletes all LUN paths that connect the volumes to the cluster, or host. NOTE: Unallocating volumes does not delete existing volume data.
If the task is not completed, click the task name for details. Replicating volumes This module describes how to replicate volumes. About replicating volumes (pair management) Volume replication is used to make copies of critical data for volumes allocated to hosts. You can make a local copy of a volume in the same storage system, or make a remote copy of a volume in a different storage system.

Changing the status of a copy pair You can change the status of a copy pair. 1. 2. From the Actions menu, select Manage Replication to start Replication Manager. From the Hosts tree, select a host and click Refresh Hosts. All copy pairs associated with that host are refreshed. 3. 4. 5.
After completing these operations, check their effect from the Mobility tab and then perform any other necessary data optimization operations. By repeating this process, the placement of data can be optimized. The following figure shows the process of optimizing data placement. From the Mobility tab, data placement can be optimized from either the application (logical group) perspective or from the THP/Smart pool perspective.
• Expanding THP/Smart volumes and reclaiming zero pages 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.
The information displayed when each THP/Smart pool is selected is as follows: • Summary Summarizes information in a list, such as the total capacity and usage of THP/Smart pools, and the reservation rate. Based on this information, you can review the usage status of the THP/Smart pool. If a Smart pool is selected, the following information can also be viewed: • Tier Summary Checks information such as drive type, drive rotational speed, and capacity usage rate of each hardware tier.
Optimizing data placement in a THP/Smart pool Tasks to complete beforehand: • A Tiered Storage Manager license must be registered. • An HP StorageWorks P9000 Performance Advisor software license must be registered (when referencing performance information). • Smart pools are being monitored (when referencing Performance Utilization or IOPS for a hardware tier). Data placement can be optimized in a THP/Smart pool. 1. 2. 4. From the tree view of the Mobility tab, select THP Pools.
• During migration, data can still be accessed. • When data migration is completed normally, the LDEV ID and host I/O of the migration source volumes are changed to those of the migration target volumes. The procedure for accessing migrated data is not changed before or after migration. • If linked with HP StorageWorks P9000 Performance Advisor software, parity group busy rate for the migration source volume and migration target volume can be checked.
Volume migration requirements All volumes for which data migration is to be performed must meet the following conditions: • Migration-source and migration-target volumes exist within one of the following storage systems (chassis): • P9500 Disk Array • XP24000/XP20000 • XP12000/XP10000/SVS200 • The emulation type, number of blocks, and size are the same for the source and target migration volumes.

5 Monitoring managed resources and resolving alerts This module describes how to monitor managed resources and alerts in a Storage Area Network (SAN). Viewing information summaries This module describes how to view summary information for registered storage systems and hosts. About checking system status in the dashboard The HP StorageWorks P9000 Command View Advanced Edition Suite dashboard shows a summary of tasks, alerts, and activities of registered storage systems.
Click host links to see volume details in the Resources tab related to capacity, used capacity, and volume type. By checking this capacity information, you can efficiently use storage resources and determine whether to migrate data to THP/Smart volumes. • Tier Residency A chart checking the usage of hardware tiers for each logical group.
About the storage systems tree HP StorageWorks P9000 Command View Advanced Edition Suite lists registered storage systems and summaries in the storage systems tree on the Resources tab. You can find list of: • THP/Smart Pools • Parity groups • Volumes • Open-Allocated • Open-Unallocated • Open-Reserved • Mainframe-Unspecified • External Storage The Storage Systems tree is the starting point for changing the configuration of these resources.
About tasks in the global monitoring bar The global monitoring bar is a convenient method for reviewing and managing task information. Task status links include a number indicating a task count, and provide easy access to the following task categories: • • • • Waiting In Progress (In Progress, Stopping, Stopping Immediate, Canceling, or Deleting) Completed (Completed, Canceled, or Stopped) Failed Clicking a task status link will display a dialog box where you can review and manage listed tasks.
In addition, settings can be specified so that alerts are reported when SNMP traps are received from storage systems and the contents of alerts are automatically sent by email. For details on these settings, see the HP P9000 Command View Advanced Edition Suite Software Administrator Guide. Confirming an alert You can list alerts, review alert details, and delete alerts. 1. 2. On the Tasks & Alerts tab, click All Alerts.

On the Administration tab, click Users and Permissions and then click Users. Select the target user and click Change Permission.
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. When external authentication is available, new user accounts created without a password value are automatically configured to use external authentication (for example, LDAP is selected for you). Fill in the desired fields, and click OK to create the user account. 3. 4.
• If multiple DNs are listed, you can remove an entry with the "-" button • Reset clears all DN entries 5. 6. From the Group List, click the Group Name link, then click Change Permission and set the Command View AE Suite permissions for the group (repeat this for each new group). Your groups will now be visible from the Administration tab, User Groups. You can affiliate the groups with resource groups and roles, just like Command View AE Suite user groups.
Physical configurations such as parity groups, and logical configurations such as LDEV IDs, can be used to create resource groups. Resource groups can then be assigned to user groups. Access control examples for P9500 Disk Array The following is an example of using resource groups to control access in a P9500 Disk Array storage system. One method for division would be to separate resources by company location.
Resource groups Resources are grouped by storage system, parity group, LDEV ID, storage port, etc. Three types of resource groups exist: • All Resources is a resource group that includes all resources managed by Command View AE Suite. This group is automatically created during installation. • Default resource groups are resource groups created for each storage system and include all resources in that storage system. This group is automatically created when a storage system is registered.
• LDEV IDs: Includes parity groups and volumes in external storage systems. Non-existent ranges can also be specified. Users with Modify or higher roles for parity groups or THP/Smart pools and assigned an unused volume ID, can create a volume. • Storage Ports: Users with Modify or higher roles for ports and assigned an unused Host Group Number can create a host group that has that host group number. • Host Group Number: Non-existent ranges can also be specified.
Users are granted permissions based on permissions set for roles assigned to the user group they belong to. A user can be registered to multiple user groups. A resource group can be registered to multiple user groups. The system account does not belong to any user group. The user roles that can be assigned to each resource group for user groups are: • Admin • Modify • View A user belonging to a built-in user group cannot be registered to another user group.
Some special cases apply: • If a user has the 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 the user, the user can create a volume. • If a user has the Modify or higher roles for ports, and an unused Host Group ID is assigned to the user, the user can allocate new volumes by using that Host Group ID.
TIP: To delete user groups, select one or more user groups, and click Delete User Groups. Deleting a user group does not delete related resource groups. Editing a user group As user information and membership in user groups change, you can update this information. 1. 2. 3. On the Administration tab, select User Groups. Select the target user group and click Edit User Group. Change the name of the user group, or the user who manages the user group.
Setting a password policy You can set a password policy to prevent users from specifying easy-to-guess passwords. 1. 2. 3. 4. On the Administration tab, select Security. Select Password in the tree. Click Edit Settings and enter the conditions for the new password policy. Confirm the changes by selecting Password in the tree to view the updated password policy. Setting automatic account locking A user account can be automatically locked after a specified number of failed login attempts.
