This appendix describes how CA VM:Tape processes tape mounts.
You issue the MOUNT command.
CA VM:Tape verifies that you are authorized to use the specified options and to access the requested tape.
If CA VM:Tape determines that no tape drives of the correct type are available, it notifies the operator and waits for the correct type of tape drive to become available. If the correct type of tape drive is available, CA VM:Tape attaches the drive to itself.
CA VM:Tape asks the operator to mount the tape specified on the MOUNT command.
The operator sets up the tape so that you can write to it or only read it, as indicated on the mount request, then mounts the tape on the tape drive.
If the mount request specified a non-labeled or foreign tape, or specified that CA VM:Tape is to bypass label processing, CA VM:Tape prompts the operator to provide the volser on the tape’s external label. (For write mounts, the operator must enter the volser twice.) Otherwise, CA VM:Tape reads the internal label and verifies the volser automatically.
CA VM:Tape verifies that the mounted tape is the correct tape and that the tape has been set up appropriately (that is, the tape has been write-enabled or not write-enabled). CA VM:Tape then updates the TMC and the Audit file to show that the tape has been mounted.
CA VM:Tape attaches the tape drive to the requesting user ID. You now have control of the drive and can position the tape to the desired location.
CA VM:Tape sends mount completion messages to both you and the operator. The messages indicate the volser of the tape and the tape drive on which it is mounted.
CA VM:Tape adds the tape to the pointer file and removes the tape from the picklist file.
When you are finished with the tape drive, you enter the CP DETACH command to detach the drive.
