Thanks for the response, I fell my 1st explanation wasn't quit clear enough.
We have to external workstations that access our cluster system running HA. When one of the machines running HA failed, the external client could not see the mounted files system. The workstations are using the HA IP as a mount point, and when the machine that failed was brought back up the NFS mount could be navigated once again. Before failure, external workstations could access servers NFS, after failure, NFS was unavailable. I expected (wanted) the client to use the 2nd HA machine, while the 1st was offline. Does this help at all?

Sorry, but what is a "addition client"? What does it mean: "did not automatically swtich"? What exactly happened? Were the clients able to access the data on the NFS partition? > If so, how do I get round this problem so clients also switch mount points? Clients SHOULD not change mountpoints. They just should continue to work. A mountpoint (simplified) is defined by the IP address and the path. Since the path does not change from one node to the other and the Cluster IP address is also the same, the client should not mention the failover.
