The path definition is the only TSM reference I could find that has a
library status:  ONLINE=YES or NO.  Example:

ANS8000I Server command: 'q path'

      Source Name: TSM_WAYNE_LM
      Source Type: SERVER
 Destination Name: WATL26
 Destination Type: LIBRARY
          On-Line: Yes

I'm not sure if TSM will set it off line if there is a problem.  Another
approach is to use the lbtest utility that comes with TSM, but I don't know
if I'd want to be firing that up automatically.... it could interfere with
TSM activities.

BTW, we also have an L700.  Ours is attached to an HP rp7410, running HP-UX
11i.  We have 14 LTO2 drives, and 4 LTO3's on order.

We have a TSM server (5.2.2) running on a Solaris box with a SCSI
attached STK L700 tape library. TSM interfaces directly with the tape
library. Does anyone have any relatively simple method to detect whether
the tape library becomes unavailable? I was thinking of enabling some
events, have them directed to a log file & have a monitoring tool watch
for them, but it seems like it would be difficult to identify all of
them. Is there some simply way to achieve this? Perhaps "query drive" or
something on a regular basis would generate a particular error if the
library was down. I suppose a script could just see if "q drive" returns
valid response within some timeframe. Any thoughts or experience doing
this?
