In this example, a fence method (method ) has been added to each node. The name of the fence
method (name) for each node is AP C . The device (devi ce) for the fence method in each node
specifies the name (name) as apc and a unique APC switch power port number (po rt) for each
node. For example, the port number for node-01.example.com is 1 (po rt= "1"). The device name
for each node (d evi ce name= "apc") points to the fence device by the name (name) of apc in
this line of the fenced evi ces element: fencedevi ce ag ent= "fence_apc" 
i pad d r= "apc_ip_exampl e" l o g i n= "l o g i n_exampl e" name= "apc" 
passwd = "password _exampl e".
