Changing the storage pool assignment of a disk

Once a disk is assigned to a storage pool, the pool assignment cannot be changed by using either the mmchdisk command or the mmrpldisk command. You can, however, change the pool to which the disk is assigned.

To move a disk to another pool:
  1. Delete the disk from its current pool by issuing the mmdeldisk command. This will move the data to the remaining disks in the storage pool.
  2. Add the disk to the new pool by issuing the mmadddisk command.
  3. Rebalance the data across all disks in the new storage pool by issuing the mmrestripefs -P command.
