       fence_mcdata - I/O Fencing agent for McData FC switches


       fence_mcdata [OPTION]...


       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.
