AH HA...I have experienced the same thing. I chased this with support and so far
I've gotten a working as designed answer...
My gut... you have a tape drive that may appear to be online, but it it isn't!
Are you 3494 with 3590s? mtlib -l/dev/lmcp0 -qM  (query mount...and compare this
with q mount in TSM)....
If you have a tape mounted, then try a mtlib eject/demount   mtlib -l/dev/lmcp0
-f/dev/rmtx -d  (rmt for the 'invalid' mount).
Also a visual check may help...
Also a visual check may help...
check through your logs to see if you had a dismount failure (I think this was
the start to my 3 day demise).
Recycling my server cleared the problem.
I recreated the problem (messages below are only one flavor) by doing a rmdev -l
/dev/rmt0 AND TSM keeps this drive online.....
even when it tries to access it and can't.....
are you 3494shared yes???
If so, this is probably why development is saying it, so far, is working as
designed...
Call me if you like for further discussion
