VT--Recover from Lost or Damaged Backstore Tape

Virtual Volumes are stacked onto physical cartridges. Losing a single cartridge can cause the loss of multiple Virtual Volumes.

To document the Virtual Volumes on the problem Backstore Tape, customize and submit the HLQ.CCUUJCL(BACKSTOR) member to create a Backstore Report. The report will contain the VOLSERs of the primary and duplex Backstore Tapes. Copy the report to a data set and sort the report on the primary or duplex VOLSER column depending on which type the problem tape is.

If a primary and a duplex copy of the Virtual Volumes on the problem tape exist, you can run the Recycle utility with the following command to recreate the problem tape:

RECYCLE PHYSICAL(problem.volser),SOURCE(REPAIR) .

If only a primary copy of the Virtual Volumes exist and the problem tape is not lost, the same Recycle utility job can be run to recreate the primary tape with all the readable Virtual Volume files. Any Virtual Volumes that cannot be read from the problem tape should be scratched in the tape management system.

If only a primary copy of the Virtual Volumes exists and the problem tape was lost or destroyed, then the Virtual Volumes are not recoverable. They should be scratched in the tape management system.

When the Scratch Synchronization Job is executed, the Virtual Volumes that were scratched in the tape management system will be scratched in CA Vtape and their Backstore tape catalog entries will be uncataloged.
