If the Volume Master File is corrupted or destroyed, you must restore it from the most recent backup copy. The VMF can be initialized at the same time it is restored.
If the most recent updates to the VMF are not contained in the VMF backup copy, you must use the CATVMFRV procedure.
This process rebuilds all chains and attempts to repair invalidly chained multi-volume data sets.
The restore function releases auxiliary records no longer being used. The TLMS048 and TLMS049 reports may show different totals.
The VMF Index file must be re-created immediately after the VMF has been restored. See CATVMFXI - Initialize or Re-create the VMF Index File in this chapter.
