The IBM Virtualization Engine TS7700 Series is the latest in the line of tape virtualization products that has revolutionized the way mainframe customers utilize their tape resources. As the capability of tape virtualization has grown, so has the need to efficiently manage the large number of logical volumes the system supports. Internal to the TS7700 Virtualization Engine, a large amount of information is captured and maintained about the state and operational aspects of the resources within the TS7700 Virtualization Engine. The TS7700 Virtualization Engine provides a management interface based on open standards through which a storage management application can request specific information the TS7700 Virtualization Engine maintains. The open standards are not currently supported for applications running under z/OS, so an alternative method is needed to provide the information to mainframe applications. This white paper describes the use of a facility of the TS7700 Virtualization Engine through which a z/OS application can obtain that information.
It is assumed throughout this white paper that the reader is familiar with using standard labeled tape volumes and MVS tape utilities.
