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.
