Checking backup related controls

For an eligible volume record (for a specified volume serial, or for each eligible volume) indicating the volume has been backed up at least once, AUDIT makes the following checks for each indicated VTOC copy data set:

• If the data set is stored on a migration volume for which there is no migration volume record in the MCDS, AUDIT reports *ERR 91.
• If the data set is stored on a DASD backup volume for which there is no backup volume record in the BCDS, AUDIT reports *ERR 92.
• If the data set is stored on backup tape:
  • If there is no backup volume record for the tape volume, AUDIT reports *ERR 92.
  • If the data set spans tape volumes, and there is no backup volume record for the second tape, AUDIT reports *ERR 93.
