NAME
       fence_kdump - fencing agent for use with kdump crash recovery service

SYNOPSIS
       fence_kdump [OPTIONS]...

DESCRIPTION
       fence_kdump  is	an  I/O	 fencing agent to be used with the kdump crash
       recovery service. When the fence_kdump agent is invoked, it will listen
       for  a  message	from the failed node that acknowledges that the failed
       node it executing the kdump crash kernel.  Note that fence_kdump is not
       a  replacement  for  traditional fencing methods. The fence_kdump agent
       can only detect that a node has entered the kdump crash	recovery  ser‐
       vice.  This  allows  the	 kdump crash recovery service complete without
       being preempted by traditional power fencing methods.

OPTIONS
       -n, --nodename=NODE
	      Name or IP address of node to be fenced. This option is required
	      for the "off" action. (default: none)

       -p, --ipport=PORT
	      IP port number that the fence_kdump agent will use to listen for
	      messages. (default: 7410)

       -f, --family=FAMILY
	      IP network family. Force the fence_kdump agent to use a specific
	      family.  The  value for FAMILY can be "auto", "ipv4", or "ipv6".
	      (default: auto)

       -o, --action=ACTION
	      Fencing action to perform. The value for ACTION  can  be	either
	      "off" or "metadata". (default: off)

       -t, --timeout=TIMEOUT
	      Numer  of	 seconds  to  wait for message from failed node. If no
	      message is received  within  TIMEOUT  seconds,  the  fence_kdump
	      agent returns failure. (default: 60)

       -v, --verbose
	      Print verbose output.

       -V, --version
	      Print version and exit.

       -h, --help
	      Print usage and exit.

STDIN PARAMETERS
       These  parameters  are  passed  to fence_kdump via standard input if no
       command-line options are present.

       nodename=NODE
	      Name or IP address of node to be fenced. This option is required
	      for the "off" action. (default: none)

       ipport=PORT
	      IP port number that the fence_kdump agent will use to listen for
	      messages. (default: 7410)

       action=ACTION
	      Fencing action to perform. The value for ACTION  can  be	either
	      "off" or "metadata". (default: off)

       timeout=TIMEOUT
	      Numer  of	 seconds  to  wait for message from failed node. If no
	      message is received  within  TIMEOUT  seconds,  the  fence_kdump
	      agent returns failure. (default: 60)

ACTIONS
       off    Listen  for  message from failed node that acknowledges node has
	      entered kdump crash recovery service.  If	 a  valid  message  is
	      received	from  the  failed  node,  the node is considered to be
	      fenced and the agent returns success. Failure to receive a valid
	      message from the failed node in the given timeout period results
	      in fencing failure.

       metadata
	      Print XML metadata to standard output.
