Same here with the patch you supplied - FYI I did:

1. Test using bacula's "btape" test routines on a Debian 5 initiator
2. "mt -f /dev/stX erase" from a Debian 5 initiator
3. Various backup runs using Seagate Backup Exec 12.5 from a Windows 
Server 2003 initiator


The tape drive is:

Vendor identification: HP
Product identification: Ultrium 2-SCSI
Product revision level: S63D

Thanks very much for the quick turn-around...

FWIW, I'm exporting the drive like this (in case it's of any use as an 
example for the docs):


#!/bin/sh -e

#
# Export the first tape drive via iSCSI as a passthrough device, and enable
# header digests, whilst limiting access to a single IP address.
#

TAPEDRIVESG=$(lsscsi -g | awk '$2 == "tape" { print $NF; exit}')
