fence_ldom

FENCE_AGENT(8)						      System Manager's Manual						    FENCE_AGENT(8)

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.
