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 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.

       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 running fence_mcdata and specifying the enable action.
