BACKUP, DUMP, MIGRATION, and PRIMARY: Specifying the type of volume

Explanation: BACKUP, DUMP, MIGRATION, and PRIMARY are mutually exclusive, required parameters specifying what type of volume to delete.

BACKUP specifies that a backup volume is reassigned as an unassigned volume or, if the PURGE subparameter is specified, deleted from DFSMShsm control.

DUMP specifies that a dump volume is disassociated from the dump class to which it is currently assigned and all record of its contents is discarded. In addition, the PURGE or REASSIGN subparameters can be specified to remove the volume from the control of DFSMShsm or to retain the associated dump class respectively. If the volume specified is part of a valid dump copy, all volumes containing part of the same dump copy are treated similarly.

MIGRATION specifies that a migration volume is changed as follows:

In the case of a migration level 1 volume, the volume is deleted from DFSMShsm control.
In the case of a DASD migration level 2 volume, the volume is no longer associated with its key range and is available for selection. If the optional PURGE subparameter is specified, the volume is removed from the control of DFSMShsm.
In the case of a tape migration level 2 volume, the volume is marked as not selected and is therefore available unless full. If the optional PURGE subparameter is specified, the volume is removed from the control of DFSMShsm if no valid data exists on the volume.

Note: In the preceding cases, DFSMShsm determines from the serial number whether the volume you have identified with the volser positional parameter is a migration level 1 volume or a migration level 2 volume.

PRIMARY specifies that a primary volume (a volume added using the ADDVOL command or an SMS-managed volume) is deleted from DFSMShsm control. DFSMShsm removes the record of the deleted volume from the MCDS.

Defaults: None.

Note:

If you issue the BACKUP parameter of the DELVOL command while the backup volume is in use, the command fails.
If you issue the MIGRATION parameter of the DELVOL command while automatic volume space management or automatic secondary space management is running, the command fails.
If you issue the PRIMARY parameter of the DELVOL command while that volume is being processed by automatic space management, automatic backup, or automatic dump, the command fails.
If you issue the DUMP parameter of the DELVOL command while automatic dump is running, the command fails.
If you use the MIGRATION parameter of the DELVOL command to delete a migration level 2 tape volume that has incomplete data set information saved in the OCDS TTOC record, the command fails.
