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.
2. Type parameters in the file according to the fencing device (or devices) needed:
a. For each APC MasterSwitch fencing device, specify the following parameters:
DeviceName, the fencing agent (
LoginName, and LoginPassword. Refer to Example 6-2 for a
