Use
disk = [ 'iscsi:scsi-0ATA_ST3200826AS_Linux_ATA-SCSI_simulator,hda,w' ]
and drop a script into /etc/xen/scripts/block-iscsi
that handles it. (I'm assuming now that scsi-0ATA_ST... is a unique
identifier here; otherwise chose a different property of your iSCSI
target.)

Unless I misunderstood something, that suggestion of Mark really 
solves your problem.

Best,
