NAME
fence_sanbox2 - I/O Fencing agent for QLogic SANBox2 FC switches
SYNOPSIS
fence_sanbox2 [OPTION]...
DESCRIPTION
fence_sanbox2 is an I/O Fencing agent which can be used with QLogic
SANBox2 FC switches. It logs into a SANBox2 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_sanbox2 accepts options on the command line as well as from
stdin. fenced sends parameters through stdin when it execs the agent.
fence_sanbox2 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 switch. When the fenced machine is ready to be
brought back into the GFS cluster (after reboot) the port on the FC
switch needs to be enabled. This can be done by running fence_sanbox2
and specifying the enable action.
