NAME

pvdisplay - display information about physical volumes in LVM volume groups

SYNOPSIS

/usr/sbin/pvdisplay

[-v][-d][

-b BlockList ] pv_path ...

/usr/sbin/pvdisplay -l

[-u] pv_path ...

/usr/sbin/pvdisplay -F

[-d][-v

] pv_path ...

Remarks

If physical volume input arguments belonging to a combination of volume groups version 1.0 and 2.0 or

higher, the arguments may not be processed in the order they are listed on the command line.

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.

-b BlockList For each block in BlockList , display information about the block. BlockList is a

comma separated list of blocks in

DEV_BSIZE units.

-d For each physical volume, display the offset to the start and end of the user data in

1KB byte blocks from the beginning of the PV, specify if pv_path is a bootable physi-

cal volume, and display the number of bad blocks that were relocated. These

details are displayed in addition to other information.

-F Produce a compact listing of ﬁelds described in Compact Listing (-F Option) . The

output is a list of colon separated ﬁelds formatted as key

=value[,

value ...].

-l Check whether pv_path refers to a disk device under HP Logical Volume Manager

(LVM) control.

-u If pv_path is an LVM disk, display the start and end of the user data in 1KB blocks.

-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.

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 (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

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.
