In our VMware environment, we're using the following configuration,
and it works (also with the vmware nmp multipathing method). It's
already possible to specify vendor and scsi_id (the scsi id will
become the T10 address), but you'll have to use the direct-store method
<target iqn.2004-01.nl.xtg:iscsi-server1>
direct-store /dev/sdb
initiator-address ALL
incominguser xxxx xxxx
scsi_id 00010001
vendor_id XTG
lun 12
</target>
