3.27 Chapter 60. MIGRATE Command for DFSMShsm: Requesting a Space Management Function
Note, that the first four commands are only for diagnosis and repair. Also causes the data set backup switchtapes action to occur immediately.
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. Use the following commands to directly manage data sets or volumes as opposed to the automatic management functions of DFSMShsm: Deletes all eligible expired backup versions from all backup volumes.

Update specific fields within the control data sets: 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 refedence interference. DFSMShsm Storage Administration Reference This topic contains detailed explanations of the administratino, storage administrator, and system programmer commands, which are listed in alphabetical order.
Other commands can also run for a long time. Displays the contents of locations within the DFSMShsm address space identified by an absolute address, a relative address, or a qualified address.
This topic contains detailed explanations of the operator, storage administrator, and system programmer commands, which are listed in alphabetical order. Moves all migration copies meeting a specified age criteria between DFSMShsm migration or backup volumes. Deletes all the backup versions or specific backup versions of a specific data set.
Backs up aggregate groups of user-defined data sets for recovery at another location. Table 2 shows these commands and the SMS construct that assumes their functions.
Deletes one or more unneeded fast replication backup versions. The list command that is causing you trouble does not restart. Combines the entries in the journal data set with a restored backup copy of one or all of the control data sets.
DFSMShsm Storage Administration Reference
Removes a volume from the list of volumes managed by DFSMShsm and changes existing volume information. Creates a backup version of a specific data set. Use the following commands to maintain and recover the control data sets and the DFSMShsm address space. Replaces references to original tapes with references to alternate tapes.
Replacing cartridge-type tape volumes with their alternate volumes TRAP command: Long-running commands are limited to having only one of each such command being performed by DFSMShsm at any time. Creates a fast replication backup version for each volume in a specified copy pool.
If a command is running for a long time and is returning data to your terminal, you aadministration be prevented from performing other operations at your terminal. A specific request number All requests for a particular user All requests for a particular data set.
Requesting a fast replication recovery HOLD command: In an SMS environment, the storage management functions defined in the management class and referemce 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.
Use the following commands and parameters to determine status: It also defines the automatic backup cycle, the secondary space management cycle, the dump cycle, dump classes, dfsmss volumes for aggregate recovery, and times for acministration demounting tapes currently in use by data set backup.
Deletes a migrated data set without recalling the data set. Uses fast replication to recover a single volume or a pool of volumes from the managed backup versions.
