This is similar to a recent question, but I think it is different.
If I have two volumes on the same SAN and two cluster nodes mounting one of the volumes, and I have all the VM guests on the same volume, and that volume dies, not the hosts, the underlying storage volume on my SAN (not the SAN, just the volume/iSCSI LUN), am I correct I lose all my VMs?
If that is correct, is there any reason I need more than one SAN volume for my VMs, instead of one giant disk volume, iSCSI LUN, mounted by the cluster nodes? I can't think of a reason I need more than one volume as opposed to one big volume managed by the VMware clustering software.
