Changing the names of the backup data sets

You can change the naming conventions for the backup data sets by performing the following steps:
  • Issue the SETSYS CDSVERSIONBACKUP command using the subparameter for the data set names assigned to the backup data sets. Specify the new naming convention used to back up the control data sets.
    Rule: You must change the naming convention for the backup data sets in all procedures that DFSMShsm uses. For example, update the ARCCMDxx member of the DFSMShsm startup procedure if you have specified the SETSYS CDSVERSIONBACKUP command.
  • Rename any current backup versions of the control data sets to the new naming convention if the backup data sets are on DASD. Also, you must rename any “unused” backup versions.
  • Uncatalog the old backup data sets so the tape management function can reuse the tape if the backup data sets are on tape. During backup of the control data set, you might receive message ARC0747I, which indicates DFSMShsm could not uncatalog the oldest version using the new backup names. The tape backup copies are successfully made.
