fence_mcdata(8)						       fence_mcdata(8)

NAME
       fence_mcdata - I/O Fencing agent for McData FC switches

SYNOPSIS
       fence_mcdata [OPTION]...

DESCRIPTION
       fence_mcdata  is	 an I/O Fencing agent which can be used with McData FC
       switches.  It logs into a McData 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.

       fence_mcdata accepts options on the command line as well as from stdin.
       fenced  sends  parameters  through  stdin  when	it  execs  the	agent.
       fence_mcdata can be run by itself with command line  options  which  is
       useful for testing.

       After  a	 fence	operation  has	taken  place the fenced machine can no
       longer connect to the McData FC switch.	When  the  fenced  machine  is
       ready  to  be brought back into the GFS cluster (after reboot) the port
       on the McData FC switch needs to be enabled. This can be done  by  run‐
       ning fence_mcdata and specifying the enable action.
