Specifying the tape mount parameters z/OS DFSMShsm Implementation and Customization Guide SC23-6869-01 |
|
When DFSMShsm dynamically allocates a tape device, dynamic allocation does not issue a mount message. Later, OPEN processing issues the mount message (IEC501A) during a shared enqueue on the task input/output table (SYSZTIOT) resource. The shared enqueue is preferred over the exclusive enqueue because multiple functions can process while awaiting a tape mount. |
