I"m working on migrating our 2012 Failover cluster to 2012 R2. I've got a few nodes running R2 and setup the new cluster. I however, can not get it connected to the shared storage. Does this have something to do with it alreadybeing connected on another cluster? I'm working off of this guide:

It definitely seems possible according to the guide but I'm unable to add the volumes on the new cluster. When I make the iSCSI connection and bring the drive online its shown as "RAW". What am I missing?
