Multipath is more a SAN thing, - not a tcp/ip. You should use something like LACP group on two (or more) of your network interfaces. Also you will have to configure your switch accordingly. You will not have to worry about second ip. LACP bonded interface will use one IP, but will fail-over to

Nice, now it's crystal clear. This is an Huawei Oceanstor disk array which we want to test with ovirt so we can see performance, how ovirt behaves with situations where one controller is disconnected etc., that's why we wanted to implement multipath. Thanks for the insight! James 2016-08-04

Hello Chris, Correct me if I'm wrong but I think Dan meant target's IPs. So if you have a SAN backend with two IP addresses, you first discover LUNs from first IP address, then discover LUNs from the second IP address, and so on... once you have them all, you just check them and click on "OK" so

I guess you mean the 'iSCSI multipath' sub-tab under the 'Datacenters' tab. There you can assign one or more networks to a iSCSI backend. In my opinion you cannot have more than one interface within the same network segment to do multipath, as you would have connectivity issues (not sure if ovirt
