Moves all migration copies meeting a specified age criteria between DFSMShsm migration or backup volumes. 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. Use the following commands to directly manage data sets or volumes as opposed to the automatic management functions of DFSMShsm: Replacing cartridge-type tape volumes with their alternate volumes TRAP command: Creates a fast replication backup version for each volume in a specified copy pool.

Creates a backup version of a specific data set. Combines the entries in the journal data set with a restored backup copy of one or all of the control data sets. Deletes all the backup versions or specific backup versions of dfssm specific data set.

To stop such a command from interfering with your use of your terminal, have the computer system operator issue a HOLD command for the function that is causing the interference. Removes a volume from the list of volumes managed by DFSMShsm dfssm changes existing volume information.

Long-running commands are limited to having only one of each such command being performed by DFSMShsm at any time. Deletes all eligible expired backup versions from all backup volumes. The list command that is causing you trouble does not restart. In an SMS environment, the storage management functions regerence in the management class and the storage group control the SMS-managed data sets in place of the parameter or command definitions within DFSMShsm.

Use the following commands and parameters to determine status: Also causes the data set backup switchtapes action to occur immediately. 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.

Note, that the first four commands are only for diagnosis and repair. Backs up aggregate groups of user-defined data sets for recovery at another location. Other commands can also run for a long time.

Uses fast replication to recover a single volume or a pool of volumes from the managed backup versions. Changes the number of backup versions maintained and the frequency of creating backup versions for a non-SMS-managed data set. This command also corrects discrepancies in the common recall queue. Table 2 shows these commands and the SMS construct that assumes their functions. Deletes a migrated data set without recalling the data set.

Requesting a fast replication recovery HOLD command: Replaces references to original tapes with references to alternate tapes. Update specific fields within the control data sets: Deletes one or more unneeded fast replication backup versions.

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. Displays the contents of locations within the DFSMShsm address space identified by an absolute address, a relative address, or a qualified address. Dfsmss specific request number All requests for a particular user All requests for a particular data set.

Use the following commands to maintain and recover administratiom control data sets and the DFSMShsm address space.

Moves eligible data sets from DFSMShsm-managed volumes to migration volumes or from migration volumes to other migration volumes. It also defines the automatic backup cycle, the secondary space management cycle, the dump cycle, dump classes, the eeference for aggregate recovery, and times for automatically demounting tapes currently in use by data set backup.
