K,
I had basically the same situation happen today, for some unknown reason.

The environment is HP master/media server with ATL P3000 10 drive library.

All 10 drives were in down state and was unable to sense robotic device. I
could find no apparent reason as the library was online and no tapes in any
of the drives.
I ran an ioscan which displayed  the tape drives and the robotic control
devices were all seen and claimed by the system. Then I ran drivewatch
(provided from a download site from David Chapa) and when it changed each
drive to an up status they immediately went down again. Then I power cycled
the ATL and stopped and restarted  NBU (via bp.kill_all and the rc start up)
ran drivewatch with same results, still no contact with the ATL. At this
point rebooted the system and when it came back up all tape drives were
still in a down state. Ran drivewatch once again and all was well.
Everything is working fine and backups and restores have been run throughout
the day and evening without incident.

With NBU 3.4 I have had some strange quirks appear but, have found over the
last year, when I perform a monthly maintenance re-boot they will occur a
lot less frequently.

I don?t have an answer but I have been experiencing a very similar issue (as
well as other oddities).
Hope this helps shed some more light on the problem.
