This appendix provides tables with parameter descriptions of fence devices as well as the name of the fence agent for each of those devices.
The parameter for a fence device specifies an arbitrary name for the device that will be used by Red Hat High Availability Add-On. This is not the same as the DNS name for the device.
Certain fence devices have an optional parameter. The parameter allows you to specify that a fence-device password is supplied from a script rather than from the parameter. Using the parameter supersedes the parameter, allowing passwords to not be visible in the cluster configuration file (/etc/cluster/cluster.conf ).
