I've created a 3 node failover cluster for the purpose of having a 2 active 1 passive Exchange 2007 SCC. Before creating it I had SAN LUNS created and made available to the 3 servers. i want each of the 2 active servers to own 2 disks each, but the cluster disks seems to stay together with 1 server. If I stop cluster services on the owner of the disks they all failover to another. Will I be able to control which disks are associated with which server after I install Exchange? What is the command to have the disks move to another server? i can't seem to have them move unless the cluster services are stopped.
