++.TH MPATHCONF 8 "June 2010" "" "Linux Administrator's Manual"
++.SH NAME
++mpathconf - A tool for configuring device-mapper-multipath
++.SH SYNOPSIS
++.B mpathconf
++.RB [\| commands \|]
++.RB [\| options \|]
++.SH DESCRIPTION
++.B mpathconf
++is a utility that creates or modifies
++.B /etc/multipath.conf.
++It can enable or disable multipathing and configure some common options.
++.B mpathconf
++can also load the
++.B dm_multipath
++module, start and stop the
++.B multipathd
++daemon, and configure the
++.B multipathd
++service to start automatically or not. If
++.B mpathconf
++is called with no commands, it will display the current configuration.
++
++The default options for mpathconf are
++.B --with_module
++and
++.B --with_chkconfig.
++The
++.B --with_multipathd
++option is not set by default.  Enabling multipathing will load the
++.B dm_multipath
++module and chkconfig
++.B multipathd
++to start on the next boot, but it will not immediately start it. This is so
++that users can manually edit their config file if necessary, before starting
++.B multipathd.
++
++If
++.B /etc/multipath.conf
++already exists, mpathconf will edit it. If it does not exist, mpathconf will
++use
++.B /usr/share/doc/device-mapper-multipath-0.4.9/multipath.conf
++as the starting file. This file has
++.B user_friendly_names
++set. If this file does not exist, mpathconf will create
++.B /etc/multipath.conf
++from scratch.  For most users, this means that
++.B user_friendly_names
++will be set by default, unless they use the
++.B --user_friendly_names n
++command.
++.SH COMMANDS
++.TP
++.B --enable
++Removes any line that blacklists all device nodes from the
++.B /etc/multipath.conf
++blacklist section.
++.TP
++.B --disable
++Adds a line that blacklists all device nodes to the
++.B /etc/multipath.conf
++blacklist section. If no blacklist section exists, it will create one.
++.TP
++.B --user_friendly_name \fP { \fBy\fP | \fBn\fP }
++If set to \fBy\fP, this adds the line
++.B user_friendly_names yes
++to the
++.B /etc/multipath.conf
++defaults section. If set to \fBn\fP, this removes the line, if present. This
++command can be used along with any other command.
++.TP
++.B --find_multipaths\fP { \fBy\fP | \fBn\fP }
++If set to \fBy\fP, this adds the line
++.B find_multipaths yes
++to the
++.B /etc/multipath.conf
++defaults section. If set to \fBn\fP, this removes the line, if present. This
++command can be used aldong with any other command.
++.SH OPTIONS
++.TP
++.B --with_module\fP { \fBy\fP | \fBn\fP }
++If set to \fBy\fP, this runs
++.B modprobe dm_multipath
++to install the multipath modules. This option only works with the
++.B --enable
++command. This option is set to \fBy\fP by default.
++.TP
++.B --with_multipathd { \fBy\fP | \fBn\fP }
++If set to \fBy\fP, this runs
++.B service multipathd start
++to start the multipathd daemon on \fB--enable\fP,
++.B service multipathd stop
++to start the multipathd daemon on \fB--disable\fP, and
++.B service multipathd reload
++to reconfigure multipathd on \fB--user_frindly_names\fP and
++\fB--find_multipaths\fP.
++This option is set to \fBn\fP by default.
++.TP
++.B --with_chkconfig { \fBy\fP | \fBn\fP }
++If set to \fBy\fP, this runs
++.B chkconfig multipathd on
++to set multipathd to start automatically on \fB--enable\fP and
++.B chkconfig multipathd off
++to stop multipathd for starting automatically on \fB--disable\fP.
++This option is set to \fBy\fP by default.

+From c2f3abecdb76c4e7b3ec3aa418625b4f1b942496 Mon Sep 17 00:00:00 2001
+From: Malahal Naineni <malahal@us.ibm.com>
+Date: Mon, 16 Aug 2010 15:57:02 -0700
+Subject: [PATCH] option to multipath to not modify the bindinfs file
+
+initramfs is mounted read-write causing multipath to update the
+initramfs bindings file and name all multipath devices it finds using
+friendly names. The actual changes to the file are thrown away as they
+are only written to the memory image rather than to the disk image. This
+may cause the in memory updated initramfs bindings file inconsistent
+with the actual bindings file in the active root file system image when
+devices are added or removed.
+
+In other words, the boot time updated initramfs bindings file may have
+'uuid1 map to mpatha' and 'uuid2 map to mpathb', but the active root fs
+bindings file may have 'uuid1 map to mpathb' and 'uuid2 map to mpatha'
+
+The option, -B, will not modify the bindings file. It will only use the
+bindings file if needed.  This option to multipath should be used when
+invoked in the initramfs context to avoid the inconsistency.

+Date: Tue, 01 Mar 2011 19:08:24 -0000
+From: Moger, Babu <Babu.Moger@lsi.com>
+X-Patchwork-Id: 600411
+Message-Id: <E463DF2B2E584B4A82673F53D62C2EF4FF7DC637@cosmail01.lsi.com>
+To: "dm-devel@redhat.com" <dm-devel@redhat.com>
+
+Sometimes if the host is in transient state, we need to wait till the devloss timeout to
+expire before switching path group. We have seen in some cases path group switch happens
+even before the devloss timeout expire. This patch fixes the problem for rdac checker..
