The following EVM logs and SCU EDT have been provided for the following
problem...
Yesterday morning and this morning (1:30 AM), when NETWORKER kicks off it's
backup session, there are SCSI errors. The end result of these errors is to
disconnect the tape drive and thus suspend the backup. I haven't changed
anything on the system, hardware or software or NETWORKER for a few month's
now. All has been smooth sailing. I have searched the archives and found
quasi-similar problems, but none that lead to device disconnects.
Yesterday I halted the system for five minutes and physically turned off
everything, including the external DLT7000 in question. After a normal
power-up, I then manually restarted the NETWORKER backup which actually
completed the FULL backup which it aborted in the A.M. This A.M. the
scheduled backup failed immediately after trying to start.
The Questions...
1) What is the cause/solution?
2) Can a disconnected device be re-connected?
If any other material is needed please let me know.

This event is posted by the hardware support subsystem to indicate
that a component is in the unavailable state. A component in this
state cannot be reached by the operating system, and it cannot be
determined if the inability to reach it is due to a problem with
the component itself or with another component in the access path.
Action: Contact your service provider.
