VOLUMES: Specifying the volumes to be backed up or dumped

Explanation: VOLUMES(volser,...) is a required parameter specifying that DFSMShsm is to (1) back up the eligible data sets on, or (2) dump, each of the specified volumes. For volser, substitute the serial number of the volumes to be backed up or dumped. (A volume serial number appearing more than once in the list is backed up or dumped only once.) A message is issued and the backup or dump of an SMS-managed volume is not processed if:

DFSMShsm is running in a non-SMS environment
The SMS-managed volume is in initial status (contains both SMS-and non-SMS-managed data sets while in the process of being converted to an SMS-managed volume).
DFSMShsm cannot determine if the specified volume is SMS-managed.

Defaults: None.

Note:

A volume list can include both SMS-managed volumes and non-SMS-managed volumes.
If you specify the VOLUMES parameter with more than 80 volumes, DFSMShsm processes only the first 80 volumes.
If DUMP is specified with DUMPCLASS, and at least one of the specified dump classes (or the optional STACK subparameter) specifies a stacking value greater than one, DFSMShsm attempts to stack the dumps of the volumes in the order specified. A volume in use by another DFSMShsm volume function will be moved to the end of the stack.
