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.
