Cluster Verification
A cluster installation consultant will typically perform the cluster installation for you; however, verify the following to make sure that the cluster is installed properly:
*The shared drive can be accessed from the cluster nodes.
*The virtual IP address of the cluster is accessible on the public network.
*Only one Universal Messaging server instance in the cluster can access the shared drive at any given time.
