When you specify the DIRECTORYCONTROLS VOLUMES(volser...) parameter, for each volume serial number specified AUDIT cross-checks information in the volume’s directory (a VTOC or TTOC) with control records in the MCDS or BCDS, whichever applies in a given situation. AUDIT then reports any discrepancies found.
To determine the type of directory for each volume serial specified, AUDIT first checks for a volume record. If no migration volume record or backup volume record exists for a specified volume serial number, AUDIT reports *ERR 110. When AUDIT finds a volume record, its content determines what further checking is done.
When AUDIT can determine the appropriate fix for an error, the fix is included in the list report.
You can also use the AUDIT DIRECTORYCONTROLS command to verify that the catalog information data sets found on ML1 volumes correspond to a valid copy pool version.
