We have two ESXi 5.0 clusters that are connected to two unique HP 24K SANs and those SANS are replicated between each other. We have a need to transfer all of the VMs from one Cluster to the other. The idea was that we would use SAN replication to block copy the LUNs from one SAN to the other and present them to the cluster on the other side. We have done this and the ESXi hosts can see the storage but when I try to add them as a datastore the only option I have available is to format the LUN. It seems as if it is not reading the file system on the replicated datastore. The DS's are formatted with VMFS 5 and the SAN is back in Simplex mode after the replication. Has anyone seen this before or will this not work for some reason? Any ideas?
