NAME
       vgcfgbackup  -  create  or update LVM volume group configuration backup
       file

SYNOPSIS
       vg_conf_path] vg_name

DESCRIPTION
       The command saves the LVM configuration for a volume group in a default
       or alternate configuration backup file (see the option).

       By default, runs automatically each time an LVM command changes the LVM
       configuration.  In this case, it always uses the default	 configuration
       backup  file.  An existing default configuration backup file is renamed
       with an extension of

   Options and Arguments
       recognizes the following options and arguments:

	      vg_name		  The path name of a volume group.

	      Save the configuration using an alternate file name specified by
				  vg_conf_path.

				  If is omitted, the default file name	is  in
				  the form:

				  base_vg_name	is  the	 base name of vg_name.
				  For example,	if  vg_name  is	 specified  as
				  base_vg_name is

	      Update the configuration backup file with the latest LVM config‐
	      uration.
				  Only those physical volumes added since  the
				  configuration	 backup file was last modified
				  need to be online.

				  If is	 omitted,  all	physical  volumes  for
				  vg_name must be online.

RETURN VALUE
       exits with one of the following values:

	      Successful completion.
	      Failure.
		     Errors  occurred  when  information from the volume group
		     was being accessed.

EXTERNAL INFLUENCES
   Environment Variables
       determines the language in which messages are displayed.

       If is not specified or is null, it defaults to "C" (see lang(5)).

       If any internationalization variable contains an invalid	 setting,  all
       internationalization variables default to "C" (see environ(5)).

EXAMPLES
       Back  up	 LVM configuration information for volume group in the default
       backup file

       Update LVM configuration information corresponding to volume  group  in
       the default backup file

       Back up LVM configuration information for volume group in the alternate
       configuration backup file

WARNINGS
       It is recommended that any alternate configuration backup file be  cre‐
       ated  in	 the  root  file  system (as is the case with the default path
       name).  This facilitates easy volume group recovery during  maintenance
       mode, such as after a system crash.
