Hi List,

Overview
========

I am running Amanda on a GNU/Linux Debian Sarge instalation. Amanda version is 
2.4.4p3-3 . The kernel is 2.6.18-4-686.

And here is some output from boot up referencing the scsi card and tape drive:

-- start
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0
        <Adaptec 19160B Ultra160 SCSI adapter>
        aic7892: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs

  Vendor: SONY      Model: SDT-11000         Rev: 0200
  Type:   Sequential-Access                  ANSI SCSI revision: 02
 target0:0:0: Beginning Domain Validation
 target0:0:0: wide asynchronous
 target0:0:0: FAST-20 WIDE SCSI 40.0 MB/s ST (50 ns, offset 15)
 target0:0:0: Domain Validation skipping write tests
 target0:0:0: Ending Domain Validation

-- end

The tape drive is a few years old the rest of the hardware is brand new. 

Problem
=======

Whenever i run an amanda backup around 30mins into the run I get the following 
errors in the logs. I've included  a few extra unrelated lines at the beginning 
to give some context. 

>From what i can see something bad happened, an attempt was made to reset and 
>the SCSI card went offline.

So i'm finally left with the proverbial question: is it hardware or software?

I guess my question to the list is: what are these error messages saying?

Any help/pointers would be greatly appreciated.
