#
# This file contains a series of commands to perform (in order) when a
# kernel crash has happened and the kdump kernel has been loaded
#
# The commands are chained together to allow redundancy in case the
# primary choice is not available at crash time
#
# Currently only one dump target and path may be configured at once
# if the configured dump target fails, the default action will be preformed
# the default action may be configured with the default directive below
#
# Basics commands supported are:
# raw <partition> - will dd /proc/vmcore into <partition>
# <nfs mount> - will mount fs and copy /proc/vmcore to
# <mnt>/var/crash/%DATE/ , supports DNS
# <user@location> - will scp /proc/vmcore to
# <user@location>:/var/crash/%DATE/, supports DNS
# <fs type> - will mount -t <fs type> /mnt and copy /proc/vmcore to
# /mnt/var/crash/%DATE/
# ifc <interface> - instead of bringing up the interface that is normally associated
# with the next hop of the ip address you plan to use with scp or nfs
# activate this interface instead. This is sometimes needed in the event
# that the kdump kernel assigns your interface a different name, given
# that it only loads the driver needed for the specific interface you are
# going to use
# default reboot - if all of the above fail, then reboot the system
# and accept the /proc/vmcore is lost, else
# comment out 'default' to fall through and fix
# the system (if the disk is available)
# raw <partition> - Will dd /proc/vmcore into <partition>.
#
# net <nfs mount> - Will mount fs and copy /proc/vmcore to
# <mnt>/var/crash/%HOST-%DATE/, supports DNS.
#
# net <user@server> - Will scp /proc/vmcore to
# <user@server>:/var/crash/%HOST-%DATE/, supports DNS
# NOTE: make sure user has necessary write
# permissions on server
#
# <fs type> <partition> - Will mount -t <fs type> <partition> /mnt and copy
# /proc/vmcore to /mnt/var/crash/%DATE/.
# NOTE: <partition> can be a device node, label or uuid.
#
# path <path> - Append path to the filesystem device which you are
# dumping to. Ignored for raw device dumps.
# If unset, will default to /var/crash.
#
# core_collector makedumpfile <options>
# This directive allows you to use the dump filtering
# program makedumpfile to retrieve your core, which on
# some arches can drastically reduce core file size.
# See /sbin/makedumpfile --help for a list of options.
# Note that the -i and -g options are not needed here,
# as the initrd will automatically be populated with
# a config file appropriate for the running kernel.
#
# link_delay <seconds>
# Some network cards take a long time to initialize, and
# some spanning tree enabled networks do not transmit
# user traffic for long periods after a link state
# changes. This optional parameter defines a wait
# period after a link is activated in which the
# initramfs will wait before attempting to transmit
# user data.
# default <reboot | shell>
# if all of the above fail, do the default action.
# reboot: If the default action is reboot simply reboot
# the system and loose the core that you are
# trying to retrieve.
# shell: If the default action is shell, then drop to
# an msh session inside the initramfs from
# where you can try to record the core manually.
# Exiting this shell reboots the system.
# NOTE: If no default action is specified, the initramfs
# will mount the root file system and run init.
#raw /dev/sda5
#ext3 /dev/sda3
#my.server.com:/export/tmp

#default reboot
#ext3 LABEL=/boot

I have merged the following into kexec-tools-test.

H: http://www.vergenet.net/~horms/

Subject: kexec-tools: --noio option to disable I/O in purgatory code.
SN platform support PIO in a different way to generic IA64 platform. It
does not support most of the legacy I/O ports.
Give an --noio option to kexec-tools to disable I/O in purgatory code.
This patch also removed an unused io.h in kexec-tools.
Signed-off-by: Zou Nan hai <nanhai.zou@intel.com>
Edited to consistently use tabs instead of spaces for intentation,
remove one instance of trailing whitespace, and fix indentation
of noio line in options[].

.SH NAME
-kexec-tools \- Tool to load a kernel for warm reboot and initiate a warm reboot
+kexec \- Tool to load a kernel for warm reboot and initiate a warm reboot
.SH SYNOPSIS
-.B kexec-tools
+.B kexec
.RI [ options ] " files" ...
.SH DESCRIPTION
.PP
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
.\" respectively.
-\fBkexec-tools\fP does not have a man page yet. Please use "kexec -h" for help.
+\fBkexec\fP allows one to load another kernel from the currently running
+Linux kernel. Normally one would load a kernel, and possibly an initial
+ramdisk, into the currently running kernel using kexec and then initiate
+a warm reboot by executing kexec again with appropriate option.
.SH OPTIONS
These programs follow the usual GNU command line syntax, with long
options starting with two dashes (`-').
A summary of options is included below.
-For a complete description, see the Info files.
.TP
.B \-h, \-\-help
Show summary of options.
.TP
.B \-v, \-\-version
Show version of program.
-.SH SEE ALSO
+.TP
+.B \-f, \-\-force
+Force an immediate kexec without calling shutdown.
+.TP
+.B \-x, \-\-no-ifdown
+Don't bring down network interfaces. (if used, must be last option specified)
+.TP
+.B \-l, \-\-load
+Load the new kernel into the current kernel.
+.TP
+.B \-p, \-\-load-panic
+Load the new kernel for use on panic.
+.TP
