Deleting a pool removes the ownership of the space it occupied, freeing the space for reassignment. The Delete option on the Pools page removes the selected pools from the server, including all member partitions and the data on them.
NSS pools can be deleted to create free space for other pools.
WARNING:
Deleting a pool deletes all the volumes and data in it. These volumes cannot be restored.
If the pool is created on a RAID1 device, deleting the pool deletes the RAID1 device.
