NAMEvgexport — export an LVM volume group and its associated logical volumes SYNOPSIS/usr/sbin/vgexport [-m mapfile] [-p] [-v] [-f outfile] vg_name /usr/sbin/vgexport -m mapfile -s -p -v vg_name DESCRIPTIONUsing the format of the first command line of the SYNOPSIS above, the vgexport command can be used to remove a volume group from the system. The volume group will be removed without modifying the logical volume information found on the physical volumes. The volume group identified by vg_name is removed from the /etc/lvmtab file, and the associated device files including the vg_name directory and group file are removed from the system. The volume group information and data is untouched on the physical volume. These disks can be imported to other system with the vgimport command (see vgimport(1M)). Sharable Option, Series 800 OnlyUsing the format of the second command line of the SYNOPSIS above, the vgexport command generates a mapfile that can be copied to other systems that are part of a high availability cluster and the vgimport command (see vgimport(1M)) can be used to recreate the volume group. See also vgchange(1M). The mapfile contains a description of the volume group and its associated logical volume(s) (if any). The logical volume information found on the physical volumes is not modified. Note that with this option, the volume group is not removed from the system. (See the second example below). The volume group specified in the mapfile can be shared with the importing systems. The volume group is not removed from the exporting system. Options and Argumentsvgexport recognizes the following options and arguments:
EXTERNAL INFLUENCESEnvironment VariablesLANG determines the language in which messages are displayed. If LANG 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)). EXAMPLESExport the volume group /dev/vg01 into mapfile vg01.mymap. The volume group will be removed from the exporting system. vgexport -m vg01.mymap /dev/vg01 Export the volume group /dev/vg01 and write the disk names into the file vg01.outfile. vgexport -v -f outfile /dev/vg01 Create a mapfile to be copied to other systems in a high availability cluster to build the volume group information for the volume group, /dev/vg02. Note that the volume group is not removed from the exporting system. The importing systems will create the volume group with the vgimport command using the -s and -m options. vgexport -s -p -m -v vg02.mymap /dev/vg02 |
