Called by

The MOUNT command

Is called during MOUNT processing after the TMC record has been written to change the volume from a scratch to a saved tape. CA VM:Tape saves all the TMC fields such as COUNT, LUNIT, and so on, before this exit is called and before the tape has been attached to the user. This exit is called only for scratch and specific scratch mounts.
