Check previous error messages related to this operation for more information. If the recommended actions from other error messages do not resolve the situation (or there are no other errors messages), issue the AUDIT LIBRARY command to detect and remedy inconsistencies in the library inventory. This command restores the library volume inventory to a consistent state with the volumes that physically reside in the library. After the AUDIT LIBRARY command completes, if the volume is not in the library inventory, it will need to be checked back into the library with the CHECKIN LIBVOLUME command.
