Hello. I have a several years old installation with Networker 6.11 on NT4 SP6a,
with a dual AIT-1 30 tape Cybernetics-brand Treefrog jukebox. The server is a
dual P3 with hardware RAID 5 and a separate Adaptec 2940U2 SCSI bus attached
to the Treefrog.

Last weekend the nightly backup session failed with an error message
"nsrd: Jukebox Jukebox1 failed: Input/output error." Any attempt to mount a
tape to either drive fails with the same "Input/output error". I've experienced
this occaisionally in the past, and rebooting the tape library has always solved
it, but this time successive reboots still yields the same error message. The
unit powercycles fine and the the self-check it does runs successfully. There is
no equivalent message in the Legato error messages book.

Could anyone hazard a guess as to what happened? Or have some diagnostics I
can try, hopefully remotely, as the tape library is in a lights-out facility?
If this is a failure-mode of some part of the hardware, how can I narrow it
down? Thanks in advance. -Gary
