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.
