Correcting WORM Field Errors in VMF Records

When a Write Once Read Many (WORM) volume is opened for input or output, CA TLMS will verify that the "World Wide ID" (WWID) and "Write Mount Count" (WMC) values captured from the IBM 3592 hardware match those values recorded in the VMF. When a mismatch occurs, CA TLMS rejects the tape and issues a message containing the hardware WWID and WMC.

Since WORM volumes are normally reserved for sensitive data, the proper authorities in your company should be contacted before any corrective action is taken. If it is decided to reset the VMF to accept the existing WORM values, the following procedure may be taken.
