NAME

pvdisplay − display information about physical volumes within LVM volume group

SYNOPSIS

/sbin/pvdisplay [-v] [-b BlockList] pv_path ...

DESCRIPTION

The pvdisplay command displays information about each physical volume specified by a pv_path parameter. 

Options

pvdisplay recognizes the following options:

pv_path The block device path name of a physical volume. 

-v For each physical volume, display the logical volumes that have extents allocated on the physical volume and the usage of all the physical extents. 

-b BlockList
For each block in BlockList display information about the block.  BlockList is a comma separated list of blocks in DEV_BSIZE units. 

Display Without −v Option

If you omit the -v option, pvdisplay displays the characteristics of each physical volume specified by pv_path:

--- Physical volumes ---

PV Name The block device path name of the physical volume

VG Name The path 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 (Mbytes) Size of physical extents on the volume, in megabytes (MB)

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

IO Timeout The IO timeout used by the disk driver when accessing the physical volume.  A value of default, indicates that the driver default IO timeout is being used. 

Display With −v Option

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 ---

The logical volumes that have extents allocated on pv_path, displayed in column format:

LV Name The block device path name of the logical volume which has extents allocated on pv_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 ---

The following information for each physical extent, displayed in column format:

PE Physical extent number

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

LV The block device path name of the logical volume to which the extent is allocated

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

Display With −b Option

If the -b is specified, pvdisplay lists additional information for each block specified in BlockList.

--- Block Mapping ---

The use of blocks on pv_path, displayed in column format:

Block The block number relative to the physical volume. 

Status The current status of the block: free, used, structure, spared, or unknown

Offset The offset of the block relative to the logical volume. 

LV Name The block device path name of the logical volume to which the block is allocated. 

EXTERNAL INFLUENCES

Environment Variables

LANG 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)).

EXAMPLES

Display the status and characteristics of a physical volume:

pvdisplay /dev/dsk/c1t0d0

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

pvdisplay -v /dev/dsk/c2t0d0
