I guess you are hitting this issue because the iscsi server location from where the iscsi tagets are discovered is not added to the iscsi software adapter on the host. When I added the iscsi server location, I was able to attach the cinder volume as a rdm disk :)
Having said that, it's the driver that should add the iscsi server address to the adapter (provided the adapter has Send Target Discover method enabled) and do the rescan.
I have a small patch to get this going. I will soon upload it after adding some tests.
