Tape ejects but is not put back in its slot

[zadigadabop]

Hello,
We have a StorageTek L40 tape library unit on UNIX with NetWorker 7.3.2.
I seems like all of a sudden when a job is complete the tapes eject (or unmounted?) from the drive but are not put back in its slot.
My question is this a NetWorker, OS or tape library configuration issue?
My guess is the sleep times but I have tried changing with no change in it putting the tape back in the slot it came from.
Any ideas appriciated.
Thanks

Can it b e that you did not configure the drives as "no rewind" devices? - If so, the media will be ejected at the end of a job. And of course the jukebox will not become aware of the eject process.

To amplify what 605 said:

Do a man st at the Unix prompt... about 3/4ths of the way through it explains what all of the letters of the tape drive device mean:

[tt]
/dev/rmt/[0- 127][l,m,h,u,c][n]
where l,m,h,u,c specifies the density (low, medium,
high, ultra/compressed), b the optional BSD behavior
(see mtio(7I)), and n the optional no rewind
behavior. For example, /dev/rmt/0lbn specifies unit 0,
low density, BSD behavior, and no rewind.
[/tt]

Did someone do a reconfig of the jukebox under Networker and put the device names back in wrong?

Further to 605s comment, if the tapes are rewinding and networker is unaware, then you could well be writing over your backups and not realise it ...

Turns out the problem was a bad theta drive moter in the tape library. At least so far this looks like it fixed it.
Thanks for all your advice.
