Try looking at page 12, section 5.2.1. :)

You should be able to set that with the scsi_id parameter in
iSCSILogicalUnit. If you want details on how to do it manually with
tgtadm, look at the
iSCSILogicalUnit_start() function in that RA. Should be something
along the lines of:

tgtadm --lld iscsi --op update --mode logicalunit \
                    --tid=$tid \
                    --lun=$lun \
                    --params scsi_id=$id

Hope this is useful.
