[rhev 3] add new domain fails: Could not retrieve LUNs

Hi all,

I'm trying to configure a FCP storage domain on RHEV 3.

I try to add a new domain from the console, but it can't find any LUNs: "Could not retrieve LUNs, please check your storage"

Here is the output from /var/log/rhevm/rhevm.log:

First question: do LUNs have to be visible from RHEV-H or RHEV-M?

Currently they are visible only from the hypervisor.

Our SAN device is Clariion AX150. Is it compatible with rhev 3?

Thank you very much for any hints.
