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. Tape virtualization subsystems have become an essential part of most mainframe customer’s operations. Massive amounts of key customer data are placed under the control of the subsystem. The IBM TS7700 Virtualization Engine, with its virtual tape drives, disk cache and integrated hierarchical storage management, is designed to perform its tasks will no customer involvement once it has been configured. However, as a customer, you may still need (and sometimes just want) to understand what is going on under the covers to:
• Assess the current utilization of the resources under the management of the TS7700
• Perform problem determination
• Perform proactive management of the resources
This white paper describes a facility of the TS7700 that supports a new z/OS Library Request host console command to allow an operator to request information pertaining to the current operational state of the TS7700, its logical and physical volumes and its physical resources. Although the command is primarily for information retrieval, it can also be used to initiate outboard operations. It is assumed throughout this white paper that the reader is familiar with the TS7700 and the use of host console commands and responses.
This update includes new commands added with Release 3.1.
