Deleting a Storage Pool

Before a storage pool can be deleted, ensure that:

• All volumes within the storage pool have been deleted

  Ensure that you have saved any readable data that you want to preserve by issuing the MOVE DATA command. Moving all of the data that you want to preserve may require you to issue the MOVE DATA command several times.

  Before you begin deleting all volumes that belong to the storage pool, change the access mode of the storage pool to unavailable so that no files can be written to or read from volumes in the storage pool.

  See "Deleting a Storage Pool Volume with Data" for information about deleting storage volumes.

• The storage pool is not identified as the next storage pool within the storage hierarchy

  To determine whether this storage pool is referenced as the next storage pool within the storage hierarchy, query for storage pool information as described in "Monitoring the Use of Storage Pool Space".

  Update any storage pool definitions to remove this storage pool as a subordinate storage pool in the storage hierarchy by performing one of the following:

  • Naming another storage pool as the next storage pool in the storage hierarchy

  • Entering the value for the NEXTSTGPOOL parameter as "" (double quotes) to remove this storage pool from the storage hierarchy definition

  See "Defining or Updating Storage Pools" for information about updating storage pool definitions.

• The storage pool to be deleted is not specified as the destination for any copy group in any management class within the active policy set of any domain. Also, a storage pool to be deleted cannot be the destination for space-managed files (specified in any management class within the active policy set of any domain). If this pool is a destination and the pool is deleted, operations fail because there is no storage space to store the data.
