If you never need to access the data in a disk pool again, you can choose to delete the disk pool. All data on the disk units in the disk pool is destroyed. If you delete the disk pool all disk units are removed and you can no longer access the disk pool. If you want to delete 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 DST mode before clearing or deleting them.
If you delete an independent disk pool that is participating in a clustered environment, it is recommended that you first remove the disk pool from the cluster resource group (CRG) using the Remove Cluster Resource Group Device Entry (RMVCRGDEVE) command. Under certain circumstances, you must end the CRG first; for example, if you plan to remove a subset of an independent disk pool group or remove the last independent disk pool in the CRG, use the End Cluster Resource Group (ENDCRG) command first. If you must delete the independent disk pool first, make sure you remove it from the CRG afterward.
