Removing volumes from DFSMShsm management or control

You can use the DELVOL command to remove volumes that have been made known to DFSMShsm by the ADDVOL command, or have automatically been made known to DFSMShsm. Volumes are automatically ADDVOLed to DFSMShsm in several ways; for example, an assignment of a scratch tape volume from DFSMShsm management or control, or the use of an SMS-managed primary volume.

The recycle function and the DELVOL PURGE command are the only two ways to reuse a tape volume that has been written by DFSMShsm.

When SMS storage groups are changed, use the DELVOL command to remove, from DFSMShsm control, volumes that were removed from the SMS storage groups before daily automatic functions started. DELVOL these volumes on all DFSMShsm systems that know about them. Do this so that the MVT entries will not be present.
