3.5. Testing the IPMI Fence Device Configuration
To check whether the configuration you have defined works as expected, you can use the
fence_node to fence a node manually. The fence_node program reads the fencing settings from
the cluster.conf file for the given node and then runs the configured fencing agent against the
node.
To test whether the IPMI management boards have been successfully configured as fence devices for
the three nodes in cluster ipmiclust, execute the following commands and check whether the nodes
have been fenced.
# /sbin/fence_node clusternode1.example.com
# /sbin/fence_node clusternode2.example.com
# /sbin/fence_node clusternode3.example.com
