What does /usr/sbin/inquire show? Does it report your tape library?
What about /proc/scsi/scsi ?

What about /usr/bin/sg_map ? Does it report all the devices, including the robot? Can you run 'mt -f /dev/nst#' status for each device?

Finally, is it possible that one or more modules required for proper tape functionality is not loaded? What does /sbin/lsmod report? Do you see mptbase, mptscsih, st ???

What OS are you running?

I am running Red Hat Linux (RHEL 4 32-bit and RHEL 5 64-bit).

What version of NetWorker?

When I first noticed this problem, I was running NW and it is still 
here with NW

What is your set up?

I have a NetWorker server and eight storage nodes.  The NetWorker server has 
the robot of the
tape library and the fourteen tape drives are direct attached (no switch) to 
the various
storage nodes, two storage nodes have one tape drive each, three storage nodes 
have two tape
drives each, two storage nodes have three tape drives each.

The problem hits on almost all the tape drives on both versions of RHEL.  There 
are no error
messages logged in /var/log/messages on the storage node, nor on the tape 
library to indicate
that any error really happened.
