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

Quoting Fredrik Ãslund <fredrik.aslund@xxxxxxxxxx>:
Is there a way to specify the tid of a target controller in targets.conf?
By default, tid 1 is used by tgt-admin. This means that all instances of
tgtd at different servers will have the same SCSI ID (and SCSI SN),
confusing iSCSI initiators (as VMware).
This patch will allow targets.conf to include:
--
<target iqn.2011-06.com.example:storage1>
backing-store /dev/system/iscsi_storage1
scsi_id storage1_
scsi_sn storage1_
controller_tid 11
</target>

Is there a better way to accomplish this?
