Scratch Tape Synchronization › Scratch Tape Synchronization

Scratch Tape Synchronization

As Virtual Volumes are expired, CA Vtape must be notified for the following actions to be taken:

• Changing the status of the Virtual Volumes in the Global VCAT.
• Renaming of the Virtual Volume files on the Linux Server. The renamed files will not be deleted until three days have passed by default.

In general, notification is performed by executing a batch Scratch Synchronization Job specific to the installed Tape Management System. If other scratch synchronization processes are available, they are discussed in the section specific to the installed Tape Management System.

The Scratch Synchronization Job should be scheduled to run after the normal Tape Management System expiration cycle has completed.

The Scratch Synchronization Job only needs to be run once in a CA Vtape Complex since the Global VCAT is shared.

Important! When multiple CA Vtape Complexes are installed, you should execute all steps of the appropriate Scratch Synchronization Job, in the order provided, once for each Complex. If you do not, you could deplete all available scratch tapes or scratch active Virtual Volumes, causing a data loss.

The following sections of this chapter document the scratch synchronization process and other requirements for specific Tape Management Systems. Review the section for your Tape Management System and take the required actions.
