Migrating data for volume performance
You can migrate data based on the results of monitoring volume performance:
Tasks that must be completed beforehand:
• A Tiered Storage Manager license must be registered.
• Creation of a tier in which the target mainframe volumes are grouped (only when migrating
mainframe volumes)
Information that should be obtained beforehand:
• Migration source host, logical group, tier, or storage system.
• Migration target THP/Smart pools, tier or migration target volumes.
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 tier.
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/Smart 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.
