You can change the performance characteristics of your
data by migrating the volumes where the data is stored to a pool with
different drive classes. You can also migrate data to another pool
if you want to isolate or balance workloads.
Before you begin
Ensure that the target pool has the same storage type and
is on the same processor node as the source pool and that it has sufficient
available capacity to contain the migrating volumes.
Tip: Capacity
bars for all eligible target pools are displayed in the Migrate
Volumes window in the DS8000® Storage
Management GUI.
Procedure
- Migrate data between pools by using the Migrate action on the
Volumes by Pool page in the DS8000 Storage
Management GUI. You can track the progress in either the task progress window or
the State column in the Volumes by Pool table.
- Wait for the migration to complete before you attempt to
access data on the migrating volumes.
