Yep...

Both LUNs have the same ID name, which confuses discovery (I've done the
same thing before).  This is a 16 character string, so make sure they
are distinct/unique in that 16 characters.

It is annoying that scsi-target-utils lets you do this.

Arghhh!
Actually the name I used is
p_iscsi_store1_lun1
p_iscsi_store1_lun2

and the problem so should be that it is trimmed to 16 chars... I will try

Thanks!!


The original problem actually was to configure a new iSCSI lun for VMware on the same store provided by scsi-target-utils and this new lun was not visible...
So I tried originating with oVirt to crosscheck....
Now, after changing the ID, I have

# tgtadm --lld iscsi --mode target --op show | grep "SCSI ID"
            SCSI ID: IET     00010000
            SCSI ID: p_iscsi_store1_l
            SCSI ID: p_lun2_istore1

and the result is that VMware is able to see the new lun ;-)
But the same didn't originate any change at oVirt side: the discovery, with and without chap selected (see this thread that should be solved in my version that is 3.5:  http://lists.ovirt.org/pipermail/users/2014-September/027388.html) doesn't show the new LUN to attach, only LUN 1...
Any log or tes I can provide to debug problem of oVirt discovery?
