As I explained, I don't use an iSCSI server, that's what I call accessing it "directly".
Yes, my iSCSI storage is working on my first Host, it has been discovered successfully, some VM are working on it etc...
The second host can discover it so I don't think it's a network issue.

>From the vdsm logs from second host ("the non working one") it looks like it can even see the LVM on it, right ?

Yes I have an network interface working on the second host, which is ovirtmgmt. I can access all other storage correctly from that host without errors. I can discover the iSCSI.

As it is a multipath iSCSI, does it need to acces one different path for each host ? I didn't set anything about iSCSI bonding, I use only one single interface on each host.
