Thanks for the tip Len.
I don't use show commands in scripts, because A) we're warned that they are
unsupported and subject to change without notice, and B) they're a pain to
parse. But that does indeed show the library status. As for the ANR8440
msg, that would only happen during TSM startup, woudn't it? When it tries
to initialize the library?
Off-topic (a little) -- another thing I'd like to be able to see is what
tapes (if any) are in the import/export slots. The 'show slots' command
lists what slots exist, but not what tapes are in them. Some libraries
provide a telnet interface that would probably work, but not the L700
(sigh).

Hello Robin,
There is an undocumented command show library that has the online status.
See the archives for more info on undocumented commands.
Here is the partial output from the show library command and the query path
command.
Autolib is an stk 9710 which was not connected. But at least with a
connected library the show library command will show the library as offline
if it can not talk to it.
You do get the following message in the tsm log for an unconnected library
08/09/2006 09:09:05 ANR8440E Initialization failed for SCSI library
AUTOLIB;
will retry in 2 minute(s).

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?
