DUMP: Preventing dumps

Explanation: DUMP is an optional parameter specifying whether DFSMShsm prevents all dump processing (command and automatic) or prevents only automatic dump processing. The DUMP parameter, without any subparameters, specifies that all dump processing tasks are prevented. No more dump processing tasks are started. Also, any command requests that specified the WAIT keyword are failed.

Subparameter Explanation
AUTO DUMP(AUTO) specifies that automatic dump processing is prevented. No additional automatic dump processing tasks are started. You can still perform command dump processing tasks. HOLD DUMP(AUTO) also prevents auto dump tasks for fast replication copy pool volumes from starting. This setting does not affect dump tasks started through the FRBACKUP command.
FRBACKUP DUMP(FRBACKUP) specifies that dump processing of FRBACKUP target volumes is prevented. No additional FRBACKUP DUMP tasks or FRBACKUP DUMPONLY tasks are started.

The point at which DFSMShsm stops dump processing is controlled by the ENDOFDATASET and ENDOFVOLUME parameters.

When a HOLD command is submitted that interrupts a dump of a copypool, if it is a NOWAIT request, the MWE for the dump remains queued until canceled or the HOLD is released. All WAIT requests are purged and must be resubmitted once the HOLD is released for the dump to take place.

Defaults: If AUTO is not specified, command dump and automatic dump processing are prevented.
