Abstract
A method and system performs a fencing technique in a host cluster storage environment. The fence program executes on each cluster member in the cluster, and the cluster is coupled to a storage system by a network. When a cluster member fails or cluster membership changes, the fence program is invoked and a host fencing API message is sent via the network to the storage system. The storage system in turn modifies export lists to restrict further access by the failed cluster node to otherwise fence the failed cluster node off from that storage system or from certain directories within that storage system.
