Deletes all the backup versions or specific backup versions of a specific data set.
Moves eligible data sets from DFSMShsm-managed volumes to migration volumes or from migration volumes to other migration volumes. Update specific fields within the control data sets: Requests that DFSMShsm back up eligible data sets on one or more volumes, in one or more storage groups, or on all primary volumes; or that it back up the control data sets.
It also defines the automatic backup cycle, the secondary space management cycle, the dump cycle, dump classes, the volumes for aggregate recovery, and times for automatically demounting tapes currently in use by data set backup.
Replacing cartridge-type tape volumes with their alternate volumes TRAP dfsmss Requesting a fast replication recovery HOLD command: In an SMS environment, the storage management functions defined in the management class and the storage group control the SMS-managed data sets in place of the parameter or command definitions within DFSMShsm. Changes the number of backup versions maintained and the frequency of creating backup versions for a non-SMS-managed data set.
See Recovering control data sets using the enhanced CDS recovery function for the recommended way to recover control data sets that run outside the DFSMShsm address space.

Deletes a migrated data set without recalling the data set. To stop such a command from interfering with your use of your terminal, have the computer stirage operator issue a HOLD command for the function that is causing the interference. This topic contains detailed explanations of the operator, storage administrator, and system programmer commands, which are listed in alphabetical order. Displays the contents of locations within the DFSMShsm address space identified by an absolute address, a relative address, or a qualified address.
Creates a backup version of a specific data set. Deletes one or more unneeded fast replication backup versions. Removes a volume from the list of volumes managed by DFSMShsm and changes existing volume information.

Use the following commands to maintain and recover the control data sets and the DFSMShsm address space. Creates a fast replication backup version for each volume in a specified copy pool.
The list command that is causing you trouble does not restart.
Also causes the data set backup switchtapes action to occur immediately. Deletes all eligible expired backup versions from all backup volumes. DFSMShsm Storage Administration Reference This topic contains detailed explanations of the operator, storage administrator, and system programmer commands, which are listed in alphabetical order.
Note, that the first four commands are only for diagnosis and repair. Use the following commands to directly manage data sets or volumes as opposed to the automatic management functions of DFSMShsm: A specific request number All requests for a particular user All requests for a particular data set. Backs up aggregate groups of user-defined data sets for recovery at another location. Use the following commands and parameters to determine status: Reverence the entries in the journal data set with a restored backup copy of one or all of the control data sets.
Moves all migration copies administratuon a specified age criteria between DFSMShsm migration or backup volumes. Other commands can also run for a long time. If a command is running for a long time and is returning data to your terminal, you can be prevented from performing other operations at your terminal.
Long-running commands are limited to having only one of each such command being performed by DFSMShsm at afministration time. Table 2 shows these commands and the SMS construct that assumes their functions.

This command also corrects discrepancies in the common recall queue. Uses fast replication to recover a single volume or a pool of volumes from the managed backup versions. Replaces references to original tapes with references dfssm alternate tapes.
