How to create a cluster shared volume to use to create a cluster

I have a NetApp with a LUN on each controller. Each LUN is mapped to a single Hyper-V Host. I'm trying to move to a clustered Hyper-V configuration with these hosts but can't seem to figure out the "which came first, the chicken or the egg" question. Everything I find out there says you need a clustered share and quorum to create the cluster but when I try to create a cluster shared LUN in SnapManager it asks for the hosts in my cluster, which leads me to believe I need to have the cluster first. I tried going through it anyhow but when I go to create the cluster in VMM I don't see any storage, or networks for that matter, to assign to the cluster. Thus the cluster validation fails. Any ideas on what order this needs to be done in?
