Here's an old script I wrote to view the contents of an IBM 7331 library.
Unfortunately our library offered no barcode reader, so you basically had to
remember where you put your last tape and what was on it. We were not using
it
in conjunction with ADSM/TSM at the time, it was being driven entirely with
tapeutil
and tar in a custom script. (not included)
Also included is the clean_stacker script. They may prove of use or give
some ideas.
For us they're now redundant as we run TSM on that site. Surprisingly, these
scripts
ran for months without incident, the only problem was when the cleaning tape
ran out of
uses, this could be easily included with a CLEANING_COUNTER of some
description.
Use/modify entirely at your own risk. I'm not responsible for any damage you
may cause.
