This checklist shows the sequence of tasks that you use to delete a basic disk pool or an independent disk pool. If you want to delete or clear an independent disk pool that is unavailable, you can do so when your system is fully restarted. For all other disk pools, you need to restart your system to Dedicated Service Tools (DST) mode before clearing or deleting them.
Attention: Make sure that you have completely saved your system in the
event that you need to recover from an error situation. Also note that when
a disk pool is deleted, all data remaining in that disk pool is lost.
