NAME¶
fence_ldom - Fence agent for Sun LDOM
DESCRIPTION¶
fence_ldom is an I/O Fencing agent which can be used with LDoms virtual
machines. This agent works so, that run ldm command on host machine. So ldm
must be directly runnable.
Very useful parameter is -c (or cmd_prompt in stdin mode). This must be set to
something, what is displayed after successful login to host machine. Default
string is space on end of string (default for root in bash). But (for example)
csh use ], so in that case you must use parameter -c with argument ]. Very
similar situation is, if you use bash and login to host machine with other
user than root. Than prompt is $, so again, you must use parameter -c.
fence_ldom accepts options on the command line as well as from stdin. Fenced
sends parameters through stdin when it execs the agent. fence_ldom can be run
by itself with command line options. This is useful for testing and for
turning outlets on or off from scripts.
