Thanks for the advice. Another person also suggested the SCSI bus and cable.

It's mildly problematic, as the SCSI bus the tape library is attached to, is
embedded on the system's mainboard, and I'm not sure the system will allow
for an add-in SCSI bus (system has two horizontal PCI slots as a 2U rack server,
and the top slot has the Mylex RAID card.)

(The server has powercycled each time the tape library was.)

(Since I'm responding also to the list...)

If there is someone who knows Treefrog libraries who could reply -- when I power
cycle the library the picker arm goes through a self-test. Near/at the end
of the test, the light on the arm changes from green to a flashing amber. After
3 or 4 powercycles the arm will POST and stay green, and I can move one tape
from the stack into a drive. At that point the light turns amber, I get the I/O
error in Legato, and the library won't respond to commands. In your mind would
you suspect SCSIbus and cable, or hardware fault on the library? I'm not sure
if the light on the picker arm represents library status or communications
status. If anyone has any insight to offer I'd be grateful. -Gary

Gary,

I don't have much experience with NT4, but your problem sounds like you
might have a bad SCSI cable or card.  If you have a spare cable, I'd swap
that and see what happens to the problem.  I'd recommend shutting down the
NT4 machine before disconnecting the SCSI cable.

Also, you didn't indicate that you've cycled the NT4 machine.  The problem
could be with the server.
