It does: the above config would generate the following commands (assuming /dev/sdb is a WD disk):

# Adding target: iqn.2004-01.nl.xtg:iscsi-server1
tgtadm -C 0 --lld iscsi --op new --mode target --tid 1 -T iqn.2004-01.nl.xtg:iscsi-server1
tgtadm -C 0 --lld iscsi --op new --mode logicalunit --tid 1 --lun 12 -b /dev/sdb  
tgtadm -C 0 --lld iscsi --op update --mode logicalunit --tid 1 --lun=12 --params scsi_id="00010001"
tgtadm -C 0 --lld iscsi --op update --mode logicalunit --tid 1 --lun=12 --params vendor_id="XTG"
tgtadm -C 0 --lld iscsi --op update --mode logicalunit --tid 1 --lun=12 --params product_id="WDC WD10EADS-00M"
tgtadm -C 0 --lld iscsi --op update --mode logicalunit --tid 1 --lun=12 --params product_rev="01.0"
tgtadm -C 0 --lld iscsi --op update --mode logicalunit --tid 1 --lun=12 --params scsi_sn="WD-WMAV50144868"
# Write cache is enabled (default) for lun 12.
tgtadm -C 0 --lld iscsi --mode account --op delete --user=xxxx
tgtadm -C 0 --lld iscsi --mode account --op new --user=xxxx --password=xxxx
tgtadm -C 0 --lld iscsi --mode account --op bind --tid=1 --user=xxxx
tgtadm -C 0 --lld iscsi --op bind --mode target --tid 1 -I ALL
