NAME
fence_brocade - I/O Fencing agent for Brocade FC switches
SYNOPSIS
fence_brocade
[OPTION]...
DESCRIPTION
fence_brocade is an I/O Fencing agent which can be used with Brocade FC
switches. It logs into a Brocade 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_brocade accepts options on the command line as well as from stdin.
fenced sends parameters through stdin when it execs the agent. fence_brocade
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 Brocade FC switch. When the fenced machine is ready to be brought back
into the GFS cluster (after reboot) the port on the Brocade FC switch needs to
be enabled. This can be done by running fence_brocade and specifying the
enable action.
