I have iSCSI vbd based domUs working in SuSE10.1, xen-3.0.2 and 
open-iscsi-0.5.545-9 against an IET server.

Is sdb partitioned? iSCSI attaches each LUN as a single block device that the 
dom0 needs to partition or to use whole.

I would have thought you'd want
        disk = [ 'phy:sdb,sda1,w' ]
unless you had partitioned the disk /dev/sdb on the dom0.

I have the config like this

        disk = [ 'phy:disk/by_id/scsi-0049003c...,hda1,w' ,               
                'phy:disk/by-id/scsi-0049005a...,hda2,w' ]

where /dev/disk/by-id/scsi-0049003c... would represent /dev/sdc for the domU 
root space and /dev/disk/by-id/scsi-0049005a... would represent /dev/sdd for 
the domU swap space and are individual disks as seen by the dom0. I'm using 
the /dev/disk/by-id names for each disk as these are unique names as seen by 
all iSCSI initiators and allow me to migrate live domUs between physical 
dom0s.
