I can't say for your specific case but I have a TL892 and I know I did
play around a little with the settings before I got it to work properly.
For me it was set so that when a tape is unloaded it did automatically
load next, this did of course cause some issues for bacula which was
much happier after removing that.
FYI, my setup is very close to yours, I'm running OpenSuse 10.0, Adaptec
2944UW and a TL892, all working fine as far as bacula is concerned (the
second tape drive jams now and then so I removed it)
Try to remove one library so you only have one and then run the test.
If you can't get it to work I can try btape to see what comes out for me
and if you post the library config I can compare it to mine.
The good news is that it is possible, just give it some work.
