NAME

vgdisplay − display information about volume groups

SYNOPSIS

/etc/vgdisplay [-v] [volume_group_name ...]

DESCRIPTION

vgdisplay displays information about volume groups.  If volume_group_name is specified, vgdisplay displays information for that volume group only.  If no volume_group_name is specified, vgdisplay displays names and corresponding information for all defined volume groups. 

−v Command-Line Option not Specified

If the -v (verbose) option does not appear in the command line, only the following information is displayed:

VG Name: Name of the volume group. 

VG Status: State of the volume group:

on Volume group previously activated by vgchange -a y command. 

off Volume group previously deactivated by vgchange -a n command. 

Max LV: Maximum number of logical volumes allowed in the volume group. 

Cur LV: Current number of logical volumes in the volume group. 

Open LV: Number of logical volumes currently open in the volume group. 

Max PV: Maximum number of physical volumes allowed in the volume group. 

Cur PV: Current number of physical volumes in the volume group. 

Active PV: Number of physical volumes that are currently active. 

PE Size: Size of each physical extent. 

Max PE per PV:
Maximum number (limit) of physical extents that can be allocated from any of the physical volumes in the volume group.

Total PE: Total number of physical extents within the volume group: the sum of the number of physical extents belonging to each available physical volume in the volume group. 

Alloc PE: Number of physical extents currently allocated to logical volumes. 

Free PE: Number of physical extents not allocated. 

VGDA: Number of volume group descriptor areas within the volume group. 

Total PVG: Total number of physical volume groups within the volume group. 

−v Command-Line Option Specified

If the -v command-line option is specified, vgdisplay lists additional information for each logical volume, for each physical volume, and for each physical volume group in the volume group:

Logical volumes:
Lists information about logical volumes belonging to volume_group_name:

LV Name: Name of logical volume in the volume group. 

LV Status: State of the logical volume:

available available/stale

unavailable available/syncd

available/stale
Logical volume available but contains physical extents that are not current.

available/syncd
Logical volume available and synchronized.

available Logical volume available; stale/syncd state cannot be confidently determined because logical volumes have both the Mirror Write Cache and Mirror Consistency Recovery turned off. 

unavailable Logical volume is not available for use. 

LV Size: Size of the logical volume. 

Total LE: Number of logical extents in the logical volume. 

Used PE: Number of physical extents used by the logical volume. 

Used PV: Number of physical volumes used by the logical volume. 

Physical volumes:
Lists information about physical volumes belonging to volume_group_name:

PV Name: Name of physical volume in the group. 

PV status: State of the physical volume. 

Total PE: Total number of physical extents on the physical volume. 

Free PE: Number of free physical extents on the physical volume. 

Physical Volume Group:
Lists information about physical volume groups belonging to volume_group_name:

PVG Name:
Name of physical volume group in the volume group.

PV Name:
Name of physical volume in the physical volume group.

EXTERNAL INFLUENCES

Environment Variables

LANG determines the language in which messages are displayed. 

If LANG is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of LANG. 

If any internationalization variable contains an invalid setting, vgdisplay behaves as if all internationalization variables are set to "C".  See environ(5).

EXAMPLES

Display information about all the volume groups within the system:

vgdisplay

Display all of the information about one volume group, including the characteristics and status of both the logical and physical extents of the volume group:

vgdisplay -v /dev/vg02
