ESX cluster with 2 clariion arrays

Hello,

We have an existing ESX cluster and clariion array, I was wanting to add RDM's to this cluster from a different clariion array. Is it possible to do this?

I havent found any documentation online with any details, and I am wondering if this is just as simple as zoning the cluster into the array, registering it and assigning the luns to the cluster via a storage group.
