4Subject: [PATCH 05/14] RH: add mpathconf
5
6mpathconf is a program (largely based on lvmcomf) to help users
7configure /etc/multipath.conf and enable or disable multipathing. It
8has a couple of built-in options that can be set directly from the
9command line. But, mostly it is used to get a multipath.conf file
10with the OS defaults, and to enable and disable multipathing via
11a single command.

545+.TH MPATHCONF 8 "June 2010" "" "Linux Administrator's Manual"
546+.SH NAME
547+mpathconf - A tool for configuring device-mapper-multipath
548+.SH SYNOPSIS
549+.B mpathconf
550+.RB [\| commands \|]
551+.RB [\| options \|]
552+.SH DESCRIPTION
553+.B mpathconf
554+is a utility that creates or modifies
555+.B /etc/multipath.conf.
556+It can enable or disable multipathing and configure some common options.
557+.B mpathconf
558+can also load the
559+.B dm_multipath
560+module, start and stop the
561+.B multipathd
562+daemon, and configure the
563+.B multipathd
564+service to start automatically or not. If
565+.B mpathconf
566+is called with no commands, it will display the current configuration.
567+
568+The default options for mpathconf are
569+.B --with_module
570+The
571+.B --with_multipathd
572+option is not set by default. Enabling multipathing will load the
573+.B dm_multipath
574+module but it will not immediately start it. This is so
575+that users can manually edit their config file if necessary, before starting
576+.B multipathd.
577+
578+If
579+.B /etc/multipath.conf
580+already exists, mpathconf will edit it. If it does not exist, mpathconf will
581+create a default file with
582+.B user_friendly_names
583+and
584+.B find_multipaths
585+set. To disable these, use the
586+.B --user_friendly_names n
587+and
588+.B --find_multipaths n
589+options
590+.SH COMMANDS
591+.TP
592+.B --enable
593+Removes any line that blacklists all device nodes from the
594+.B /etc/multipath.conf
595+blacklist section.
596+.TP
597+.B --disable
598+Adds a line that blacklists all device nodes to the
599+.B /etc/multipath.conf
600+blacklist section. If no blacklist section exists, it will create one.
601+.TP
602+.B --user_friendly_name \fP { \fBy\fP | \fBn\fP }
603+If set to \fBy\fP, this adds the line
604+.B user_friendly_names yes
605+to the
606+.B /etc/multipath.conf
607+defaults section. If set to \fBn\fP, this removes the line, if present. This
608+command can be used along with any other command.
609+.TP
610+.B --find_multipaths\fP { \fBy\fP | \fBn\fP }
611+If set to \fBy\fP, this adds the line
612+.B find_multipaths yes
613+to the
614+.B /etc/multipath.conf
615+defaults section. If set to \fBn\fP, this removes the line, if present. This
616+command can be used aldong with any other command.
617+.SH OPTIONS
618+.TP
619+.B --with_module\fP { \fBy\fP | \fBn\fP }
620+If set to \fBy\fP, this runs
621+.B modprobe dm_multipath
622+to install the multipath modules. This option only works with the
623+.B --enable
624+command. This option is set to \fBy\fP by default.
625+.TP
626+.B --with_multipathd { \fBy\fP | \fBn\fP }
627+If set to \fBy\fP, this runs
628+.B service multipathd start
629+to start the multipathd daemon on \fB--enable\fP,
630+.B service multipathd stop
631+to stop the multipathd daemon on \fB--disable\fP, and
632+.B service multipathd reload
633+to reconfigure multipathd on \fB--user_frindly_names\fP and
634+\fB--find_multipaths\fP.
635+This option is set to \fBn\fP by default.
