Chapter 6. Creating the Cluster Configuration System Files
Warning
Manual fencing should not be used in a production environment. Manual fencing depends on human
intervention whenever a node needs recovery. Cluster operation is halted during the intervention.

}

This example shows a node that can be fenced using a Brocade FC switch or an APC MasterSwitch.
If the node must be fenced, the fencing system first attempts to disable the node’s FC port. If that
operation fails, the fencing system attempts to reboot the node using the power switch.
