4. Specify the migration target, THP/Smart pools, 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/Smart pools are paired
properly, confirm that 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 Target 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 HP StorageWorks P9000 Command View
Advanced Edition Suite or other programs until the task has finished executing.
Prerequisites for migrating data from an SMI-S Enabled storage system to another
storage system
You can migrate data between an old and new storage system for abolishing or merging systems by
using the external storage connection function (Universal Volume Manager). The figures below provide
an example of migrating data to HP XP24000 when the SMI-S Enabled storage system is abolished.
To perform migration, use the GUI or CLI to migrate data by the system.
