DELVOL command: Removing a volume from DFSMShsm management

The DELVOL command reassigns the volume as not managed or owned by DFSMShsm. You can remove a primary volume (in this instance, PRIMARY includes both volumes added using the ADDVOL command and SMS-managed volumes), migration volume, dump volume, dump version of a copy pool, or backup volume from the list by specifying the serial number and the category of the volume you want to remove. If a DELVOL command is entered for an SMS-managed volume, the MCV record for the volume, if it exists, is deleted. You can remove only one volume each time you issue the DELVOL command unless the volume specified is part of a valid dump copy, then all volumes containing part of the same dump copy are removed from DFSMShsm.

Although you can respecify a deleted non-SMS-managed volume with the ADDVOL command, historical information about the deleted volume is lost. This information is included in the MCDS and BCDS volume records. If you use ADDVOL to respecify the volume, DFSMShsm recreates the volume record without the historical information.
