Change FC storage backend

I'm planning on migrating our RHEV storage from IBM DS4800 to IBM Storwize V7000U next week. The storwize supports virtualizing other storage, so this migration has been trivial for all our standalone servers. All I've needed to do on the servers is to update the multipath.conf to have a device section for this new storage system, and also update any "multipath { wwid=*" } where we had configured that.

Is there anything we need to do on the thin rhev-hypervisors to have it use the new storage system, or will it detect any FC-device and not care about wwid's ?
