NAME

lvdisplay - display information about LVM logical volumes

SYNOPSIS

/usr/sbin/lvdisplay

[-F][-k][

-v] lv_path ...

Remarks

If the logical volume input arguments belong to a combination of volume groups versions 1.0 and 2.0 or

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

Mirrored disk information requires the installation of the optional HP MirrorDisk/UX software, which is

not included in the standard HP-UX operating system.

DESCRIPTION

The

lvdisplay command displays the characteristics and status of each logical volume speciﬁed by

lv_path .

For volume groups 2.2 and higher,

lvdisplay can also be used to display the characteristics and status

of snapshot logical volumes. See lvm(7) for more information about snapshot logical volumes.

Options and Arguments

lvdisplay recognizes the following options and arguments:

lv_path The block device path name of a logical volume, for example,

/dev/vg00/lvol1

-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 ...].

-v For each logical volume, display the physical volume distribution, and the mapping of the

logical extents onto the physical extents of the physical volumes.

-k This option displays the same information as the -v option, except in the column where

PV Name is displayed, the pvkey (Physical Volume Number in VG) will be displayed

instead.

Use this option with the

-v option.

Display Without -v Option

If you omit the

-v option, lvdisplay displays the following information for each logical volume:

--- Logical volumes ---

LV Name The block device path name of the logical volume.

VG Name The path name of the volume group.

LV Permission The access permission and quiesce mode: The access permission is either:

read-only or read/write. If the VG containing the LV is quiesced, the

quiesce mode is displayed on the same line. The quiesce mode is either:

read/write-quiesced or write-quiesced

LV Status State of the logical volume:

available/stale

Available but contains physical extents that are not current.

available/syncd

Available with no stale extents.

available/inactive

Available but opening of the logical volume is disabled since the volume

group is activated using -l option of the vgchange command (see

vgchange (1M)).

unavailable

Not available for use.

Type of the snapshot logical volume:

Note that the states below are displayed only for snapshot logical volumes.

lvdisplay(1M) lvdisplay(1M) snapshot, space efficient Logical volume is a space efficient snapshot. snapshot, fully allocated Logical volume is a fully allocated snapshot. Snapshot Status State of the snapshot logical volume. Note that this field is only displayed for snapshot logical volumes. operative Snapshot logical volume is operative. inoperative Snapshot logical volume is inoperative. inoperative/over-commit Snapshot logical volume is inoperative and marked as over-commit.
PAGE 3
lvdisplay(1M) lvdisplay(1M) consecutive logical extents are NOT guaranteed to be located on different physical volumes. See lvchange (1M) for more information. non-strict Physical extents that belong to the same logical extent can be allocated on the same physical volume or physical volume group. PVG-strict Mirror copies for a logical extent are not allocated on the same physical volume group. strict Mirror copies for a logical extent are not allocated on the same physical volume.
PAGE 4
lvdisplay(1M) lvdisplay(1M) Display With -v Option If you specify the -v option, lvdisplay also lists the distribution of each logical volume across the physical volumes of the volume group and the mapping of each logical extent of the logical volume on the physical extents of the physical volume. --- Distribution of logical volume --The distribution of logical volume lv_path across the physical volumes of the volume group, is displayed in the following columns.
PAGE 5
lvdisplay(1M) lvdisplay(1M) PV4 The block device path name of the physical volume that corresponds to the location of the fourth physical extent(third copy) of the logical extent. PE4 Fourth physical extent number allocated to the logical extent. Status 4 Status of the fourth physical extent: stale or current. For a fully allocated snapshot, the status can be shared.
