Cluster Configuration System

Figure 1.6. Fencing a Node with Dual Fibre Channel Connections
You can configure a node with one fencing method or multiple fencing methods. When you
configure a node for one fencing method, that is the only fencing method available for fencing
that node. When you configure a node for multiple fencing methods, the fencing methods are
cascaded from one fencing method to another according to the order of the fencing methods
specified in the cluster configuration file. If a node fails, it is fenced using the first fencing
method specified in the cluster configuration file for that node. If the first fencing method is not
successful, the next fencing method specified for that node is used. If none of the fencing
methods is successful, then fencing starts again with the first fencing method specified, and
continues looping through the fencing methods in the order specified in the cluster configuration
file until the node has been fenced.
