Minimally the UTSG Tape Management System will lock the drive(s) and
manage tape mount requests, once tapes are mounted the UTSG driver
makes the mounted tape accessible to user/app via a logical device
named after the tape volume name.
eg: /dev/tape/AB0020
The UTSG Distributed Tape Subsystem extends this paradigm to systems
remote from the Linux/390 tape server(s).
