On a 3494 attached to AIX what you can do is...
mtlib -l/dev/lmcp# -qL
Now, if the I/O station has any tapes in it, (used to this would be an
"intervention required" situation but not any more at atldd.5.0.7.0.bin )

Anyway, if you have something in the I/O station, you will notice that the
message "All output stations empty" is NOT PRESENT. So you can do something
like...

mtlib -l/dev/lmcp# -qL | grep 'ALL output stations empty' 1>/dev/null 2>&1
if [ $? -ne 0 ] ; then
   echo tapes in output mode in IO station...
   fi

change the echo to anything that works for you...
You can also do this to watch for "degraded" & "intervention" situations...

I just run a job hourly from AIX that does all this and pages me (well, the
oncall person) when it finds a problem...

Subject: 3494 on MVS vs AIX


When the 3494 I/O station is full of ejected tapes (with more to come),
the MVS console automatically gets a mesage "All convenience output
stations in library TRROBOT are full."  Is there a way for either AIX or
a TSM server running on AIX to detect the condition so a email or page
could be sent to the operator.  When running a checkout libvol of more
tapes than the i/o station holds on the tsm server running on aix, the
checkout just waits until the station has been cleared.  I assume it
would timeout eventually.

AIX is v5 and TSM is 5.1.1.
