NAME

pvdisplay − display information about physical volumes within a volume group

SYNOPSIS

/etc/pvdisplay [-v] physical_vol_path ... 

DESCRIPTION

pvdisplay displays information about the physical volume or volumes specified by the physical_vol_path parameter.  If the -v (verbose) option is specified, pvdisplay displays a map of the logical extents that correspond to the physical extents of each physical volume. 

−v not Specified on Command Line

If the -v option is absent, pvdisplay displays the characteristics of each physical volume specified by physical_vol_path, namely:

PV Name: Name of the physical volume

VG Name: Name of the volume group

PV Status: State of the physical volume: available or unavailable

Allocatable: Allocation permission for the physical volume

VGDA: Number of volume group descriptors on the physical volume

Cur LV: Number of logical volumes using the physical volume

PE Size: Size of physical extents on the volume

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

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

Allocated PE: Number of physical extents on the physical volume that are allocated to logical volumes

Stale PE: Number of physical extents on the physical volume that are not current

−v Specified on Command Line

If the -v is specified, pvdisplay lists additional information for each logical volume and for each physical extent on the physical volume:

Distribution of physical volume:
Lists the logical volumes that have extents allocated on physical_vol_path:

LV Name: Name of the logical volume which has extents allocated on physical_vol_path.

LE of LV: Number of logical extents within the logical volume that are contained on this physical volume

PE for LV: Number of physical extents within the logical volume that are contained on this physical volume

Physical extents:
Displays the following information for each physical extent:

PE: Physical extent number

Status: Current state of the physical extent: free, used, or stale

LV: Name of the logical volume to which the extent is allocated

LE: Index of the logical extent to which the physical extent is allocated

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, pvdisplay behaves as if all internationalization variables are set to "C".  See environ(5).

EXAMPLES

Display the status and characteristics of a physical volume:

pvdisplay /dev/dsk/c1d0s2

Display the status, characteristics, and allocation map of a physical volume:

pvdisplay -v /dev/dsk/c2d0s2
