+It logs into a Brocade switch via telnet and disables a specified port. Disabling the port which a machine is \
+connected to effectively fences that machine. Lengthy telnet connections to the switch should be avoided  while \
+a GFS cluster is running because the connection will block any necessary fencing actions. \
+\
+After  a fence operation has taken place the fenced machine can no longer connect to the Brocade FC switch.  \
+When the fenced machine is ready to be brought back into the GFS cluster (after reboot) the port on the Brocade \
+FC switch needs to be enabled. This can be done by running fence_brocade and specifying the enable action"
