Migrating data for volume performance
To migrate data based on the results of monitoring volume performance:
1. In the Resources or Mobility tab, select a migration source host or logical group. From a list of
hosts or logical groups, you may also select migration source volumes. If migrating data from a
mainframe volume, expand the Tiers tree on the Resources tab or the Mobility tab, and then select
the corresponding tie.
2. Click the Migrate Data button.
3. Verify that the correct migration source volumes are selected, and then click the Next button.
4. Specify the migration target, THP pool or tier and then click the Next button. 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.
• Maximum Coverage: Select a candidate for the migration target from as many parity groups
as possible.
• Minimum Coverage: Select a candidate for the migration target from as few parity groups as
possible.
5. Confirm that all migration source volumes and target volumes or THP pools are paired properly,
no other problems exist, and then click the Next button. If necessary, change the pairs. To change
a pair, first select the volume pair, then from the Other Candidates for Migration list, select the
target volume to change to, and then click the Map Volume button.
6. Specify plan options as necessary and then execute the task.
7. In the tasks list, confirm the execution result of the task. After a task is created, you must not
perform operations on volumes included in the task by using P9000 Command View AE Suite.
or other programs until the task has finished executing.
Migrating data to a different storage system
Before migrating:
• An external connection must be set up to an HP StorageWorks P9500 Disk Array, XP24000/
XP20000, or XP12000/XP10000/SVS200.
• Creating a tier in which the target mainframe volumes are grouped (only when migrating mainframe
volumes).
Information that should be obtained beforehand:
• Migration target THP pool, tier or migration target volumes.
To migrate data to a different storage system:
1. From the Resources, select Storage Systems.
2. Expand the tree for the source storage system that is to be migrated, select the volumes to be
migrated from the list of external storage systems, and then click the Migrate Data button.
3. Confirm that the correct migration source volumes are selected, and then click the Next button.
