Identifying audit discrepancies

If discrepancies are found when performing an audit, they are related to you by the following means:

Scheduling error messages for full library audits are issued to your TSO logon session, unless the scheduling error occurred before any volumes from the library being successfully scheduled and that error was severe enough to prevent any other volumes in the library from also being scheduled. This early detected severe error is reported on the ISMF panel through the help facilities offered by ISMF. Messages contain the volume serial number (if known) of the volume for which the error was found and text that indicates the type of error found in attempting to validate an audit request.
If the scope of the audit is volume list or single volume, scheduling errors are not reported to your TSO logon session. These errors are indicated on return to the ISMF panel from which the AUDIT request was initiated and can be interrogated by using the message and help facilities offered through the ISMF panels. See z/OS DFSMSdfp Storage Administration for more information about the ISMF message and help facilities.
Errors incurred while attempting to perform the physical audit for any of the three audit scopes, (single volume, volume list, or full library) are reported to your TSO logon session.
After auditing a volume, the error status field (ERRSTAT) of the tape configuration database (TCDB) volume record is updated.
As notification that the audit has been completed and that the error status fields can be reviewed, a completion message is sent to you.
Note: The volume error status field contains only the last error found; no history is kept.
