Virtual Volumes

Define an exclusive range of Volume Serial (VOLSER) numbers as new scratch tapes to the tape management system before using CA Vtape the first time. These same Virtual VOLSERs are also added to CA Vtape. Most tape management systems support the definition of these new scratch tapes as Virtual Volumes or as residing in a nonexistent location. Consult your tape management system documentation for details.

The tape management system manages the Virtual Volumes as if they are real tape volumes. The only communication that is required between CA Vtape and the tape management system is to synchronize which volumes are in scratch status. This synchronization process is accomplished by adding a CA Vtape utility to the tape management system scratch process. Some tape management systems, like CA 1, have an automatic scratch notification feature that can be used instead of the CA Vtape utility program.

All the protection, management, and control services that tape management systems for real tape processing typically provide are also provided for CA Vtape Virtual Volume processing.
