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.

For detailed information on configuring fence devices, refer to the corresponding chapter in the

Cluster Administration manual.
