[Users] Unable to add iSCSI storage domain - 3.1 beta

[Trey Dockendorf]

I'm attempting to add iSCSI storage to a data center via web
interface, and while I"m able to see the target ISCSI device and
login, clicking the "OK" button doesn't submit the storage selection.
I noticed from looking at the oVirt manual that somewhere in this
interface I have to select the LUN.  However once logged into the
target I never see LUNs to select.

I've attached two screenshots that show the UI and what could be
errors in how it's being displayed.  I also attached logs from vdsm
host and engine that were captured while attempting to add the storage
domain.

After logging into the iSCSI target via web interface, this is the
output on target host, showing that my ovirt node (10.20.1.240) is
connected.

Based on some archived emails I've included previously mentioned
outputs that may help
