You are attempting to build what is called a Replicated Data Cluster. This should be documented in the UG as I recall. You will use identical DG and volume resources, with the appropriate replication management resource under the DG. To do this and comply with the EULA, you need the HA/DR Edition of VCS, to license you to use the replication agents. In an RDC, the replication agent manages read/write enabling and direction of replication. When you failover, the opposite node is write enabled, then the normal DG and volume agents bring up the storage Hugh Shannon here at Symantec is the Technical Product Manager responsible for these type configs

I have been asked to implement a VCS 5.0 cluster on Solaris 10 using replicated block-level NetApps storage. This will be a stretched cluster with one node on each of two sites and heartbeat connections using VLANs. What I am struggling with at the moment is how to configure the storage resources within VCS. I am use to defining shared volume groups/volumes but as I see it each node will effectively have a local LUN or LUNs with blocks being replicated at the array level from the active to the inactive node. Do I create separate Volume Groups and Volumes on each node and set the associated attributes on a per system basis such that failover starts the application up mounting the file system on the replica volume of the alternative node?
