Shared Tape Allocation Manager (STAM) Facility

The CA VM:Tape STAM facility lets you share tape drives among any combination of VM CPUs with shared DASD. Tape drive allocation is controlled, without operator intervention, by a database that resides on a disk shared by all systems.

Each VM system participating in tape drive sharing must use CA VM:Tape to perform all tape volume mounting and tape drive allocation. Failure to do so can result in concurrent allocation of a tape drive to multiple systems.
