Chip,
Thanks for your reply.
I am familiar with the 3584's GUI, and use it all the time. My
script was meant to be an alert. If I could count on the Operators to
remember every 30 minutes all day to go take a look at the 3584 GUI and
see if there are tapes to check out, then I wouldn't need an alert.
But our Operators are busy all day with other things, and need
to be reminded or it doesn't happen. And we have 40-60 tapes going out
every day, so if they don't empty it regularly, things back up behind
the checkout commands. The script as it is written today can count how
many tapes are in the slots, and alert when there are 24 or more, which
is better than waiting until it is totally full.
Best Regards,
John D. Schneider

Another way is to activate the 3584 GUI, and give them the link. That's
how I
enabled our operators to look at various things, such as how many slots
are
empty in the library, for those days when we get back from offsite more
tapes
than we have slots for. Ask your IBM tech. You can do all sorts of
things
with, such as update microcode/firmware, look at logs, run inventory,
send
emails, etc., etc.

John,
If I'm reading it correctly, the SML-MIB_112.mib file describes
structures in the library that can be walked with SNMP.
physicalMediaTable might be the one to look at, I have no access to a
library just at present so I can't test.
Alternatively, define another control path and use it just to run your
tapeutil commands.
