<p>I had a similar problem, in my case this was related to
multipath, it was not masking the LUNs correctly, it was seeing it
multiple times (one per path), and I could not select the LUNs in

<p>Once I configured multipath correctly, everything worked like a

</div>
<div>please do you have some
experience with
troubleshooting adding of

<div><br>
</div>
<div>I am chalenging this
issue now:</div>
<div><br>
</div>
<div>1) I have successfuly
installed oVirt 4.1.1
environment with
self-hosted engine, 3
nodes and 3 storages
(iSCSI Master domain,
iSCSI for hosted engine
and NFS ISO domain).
Everything is working now.</div>
<div><br>
</div>
<div>2) But, when I want to
add new iSCSI domain, I
can discover it, I can
login, but I cant see any
LUN on that storage. (I
had same problem in oVirt
4.1.0, so I made upgrade
to 4.1.1)</div>
</div>

<div><br>
</div>
<div>Are you sure mappings are
correct? </div>
<div>Can you ensure the LUN is
empty?</div>
<div>Y.</div>

<div>3) Then I tryed to add
this storage to another
oVirt environment (oVirt
3.6) and there are no

that storage and I can
connect it to oVirt.</div>
