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 configura-
       tion 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 configuration.
				  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 created 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.

NAME

       lvremove - remove one or more logical volumes from LVM volume group

SYNOPSIS

       autobackup] lv_path ...

   Remarks
       If the logical volume input arguments belong to a combination of volume groups version 1.0 and 2.0 or higher, the arguments may not be pro-
       cessed in the order they are listed on the command line.

DESCRIPTION

       The command removes each logical volume specified by lv_path ....

       Logical volumes must be closed before they can be removed.  For example, if the logical volume contains a  file	system,  the  file  system
       before removing it.

   Options and Arguments
       recognizes the following options and arguments:

	      lv_path		  The block device path name of a logical volume.

	      Set automatic backup for this invocation of this command.
				  autobackup can have one of the following values:

				  Automatically back up configuration changes made to the logical volume.
					 This is the default.

					 After	this command executes, the command (see vgcfgbackup(1M)) is executed for the volume group to which
					 the logical volume belongs.

				  Do not back up configuration changes this time.

	      Specify that no user confirmation is required.

   Shared Volume Group Considerations
       For volume group version 1.0 and 2.0, cannot be used if the volume group is activated in shared mode.  For volume groups  version  2.1  (or
       higher), can be performed when activated in either shared, exclusive, or standalone mode.

       Note that the daemon must be running on all the nodes sharing a volume group activated in shared mode.  See lvmpud(1M).

       When is issued, it removes the logical volume device special files from all the nodes sharing the volume group.

       When a node wants to share the volume group, the user must first execute a if logical volumes were removed at the time the volume group was
       not activated on that node.

       LVM shared mode is currently only available in Serviceguard clusters.

   Environment Variables
       determines the language in which messages are displayed.

       Remove a logical volume without requiring user confirmation:

WARNINGS

       This command destroys all data in the specified logical volumes.
