mxfence – verify fencing module configuration

Synopsis

/opt/polyserve/sbin/mxfence <server hostname or IP address>

Description

The mxfence utility can be used to verify that Matrix Server has the

information needed to fence a server. This utility is intended for server-based

fencing configurations where you must specify the hostname or IP address of

the remote controller associated with the server. You can use mxfence to

verify that Matrix Server has the correct information. The server must be up

when you use the utility and Matrix Server must be stopped on that server.

When you run mxfence, Matrix Server uses the hostname/IP address

associated with the server to access the remote controller. The server is then

either power-cycled or shut down in accordance with the method you

selected when you configured the fencing module.

If the correct server is not fenced, the hostname or IP address specified for the

associated remote controller is probably incorrect. Run mxconfig on the

server with the incorrect information and then modify the hostname or IP

address for the remote controller.
