FENCE_AGENT(8)FENCE_AGENT(8)NAMEfence_brocade - Fence agent for Brocade over telnet
DESCRIPTIONfence_brocade is an I/O Fencing agent which can be used with Brocade FC
switches. It logs into a Brocade switch via telnet and disables a spec‐
ified port. Disabling the port which a machine is connected to effec‐
tively 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 run‐
ning fence_brocade and specifying the enable action.
fence_brocade accepts options on the command line as well as from
stdin. Fenced sends parameters through stdin when it execs the agent.
fence_brocade can be run by itself with command line options. This is
useful for testing and for turning outlets on or off from scripts.
