NAME [Toc] [Back]
pvdisplay - display information about physical volumes within LVM
volume group
SYNOPSIS [Toc] [Back]
/usr/sbin/pvdisplay [-v] [-b BlockList] pv_path ...
DESCRIPTION [Toc] [Back]
The pvdisplay command displays information about each physical volume
specified by a pv_path parameter.
Options [Toc] [Back]
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 [Toc] [Back]
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 (NOTE: spare
physical volumes are only relevant if you
have installed HP MirrorDisk/UX software):
available The physical volume
is available and is
not a spare physical
volume.
available/data spared The physical volume
is available.
However, its data
still resides on an
active spare.

available/active spare The physical volume
is available and is
an active spare
physical volume.
(An active spare is
a spare that has
taken over for a
failed physical
volume.)
available/standby spare The physical volume
is a spare,
"standing by" in
case of a failure on
any other physical
volume in this
volume group. It can
only be used to
capture data from a
failed physical
volume.
unavailable The physical volume
is unavailable and
is not a spare
physical volume.
unavailable/data spared The physical volume
is unavailable.
However, its data
now resides on an
active spare, and
its data is
available if the
active spare is
available.
unavailable/active spare The physical volume
is unavailable and
it's an active
spare. Thus, the
data on this
physical volume in
unavailable.
unavailable/standby spare
The physical volume
is a spare,
"standing by" that
is not currently
available to capture

data from a failed
physical volume.
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.
Spared from PV If the physical volume represents an active
spare, this field will show the name of the
failed physical volume whose data now resides
on this spare. This information can be used
to manually move the data back to the
original physical volume, once it has been
repaired. (See pvmove(1M)). If it cannot be
determined which physical volume that the
data came from, this field will instead
display Missing PV. A missing PV would
indicate that when the volume group was last
activated or reactivated (see vgchange(1M)),
the "failed" physical volume was not able to
attach to the volume group.
Spared to PV If the physical volume represents a failed
physical volume, this field will show the
name of the active spare physical volume that
now contains the data that originally resided
on this volume. This information can be used

to manually move the data back to the
original physical volume (see pvmove(1M))
once it has been repaired.
Display With -v Option [Toc] [Back]
If -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,
current, 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 [Toc] [Back]
If -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.
Hewlett-Packard Company - 4 - HP-UX 11i Version 2: Sep 2004
pvdisplay(1M) pvdisplay(1M)
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.

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 [Toc] [Back]
Display the status and characteristics of a physical volume:
pvdisplay /dev/dsk/c1t0d0
Display the status, characteristics, and allocation map of a physical
volume:
