Manual fencing does not required any configuration.
It is just single command "fence_ack_manual" that told to survived node that you sure about second node failed and will not came up. Cluster becomes semi-automatic and depend on manual intervention. It is default behaviour if you do not define any fencing.
This command will help also in case of failure of normal fencing for some reason (power outage of fencing device can cause this) and you sure about cluster state and want to bring service back.
