lvdisplay(1M)lvdisplay(1M)NAMElvdisplay - display information about LVM logical volumes
SYNOPSIS
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 pro‐
cessed 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 command displays the characteristics and status of each logical
volume specified by lv_path.
Options and Arguments
recognizes the following options and arguments:
lv_path The block device path name of a logical volume, for
example,
Produce a compact listing of fields described in
The output is a list of colon separated fields format‐
ted as value...].
For each logical volume,
display the physical volume distribution, and the map‐
ping of the logical extents onto the physical extents
of the physical volumes.
This option displays the same information as the
option, except in the column where is displayed, the
(Physical Volume Number in VG) will be displayed
instead.
Use this option with the option.
Display Without -v Option
If you omit the option, displays the following information for each
logical volume:
The block device path name of the logical volume.
The path name of the volume group.
The access permission and quiesce mode:
The access permission is either: or
If the VG containing the LV is qui‐
esced, the quiesce mode is displayed
on the same line. The quiesce mode
is either: or
State of the logical volume:
Available but contains physical
extents that are not current.
Available with no stale extents.
Not available for use.
Number of mirror copies.
Mode of mirror consistency recovery which determines how
LVM
performs mirror consistency recovery
during volume group activation:
Recover mirror consistency by using
the Mirror Write Cache
and Mirror Consistency
Record. Implies that Mir‐
ror Write Cache is on.
Recover mirror consistency by going
through all logical extents
and copying data from a
non-stale copy to the other
mirror copies. Implies
that Mirror Write Cache is
off.
No mirror consistency recovery during
volume group activation
on this logical volume fol‐
lowing a system crash. The
user of the logical volume
is responsible for ensuring
mirror consistency.
Implies that Mirror Write
Cache is off.
Striped, sequential or parallel scheduling policy.
Striped policy is by default parallel
scheduling for mirrored I/O.
Size of the logical volume in megabytes (MB).
Number of logical extents currently in the logical vol‐
ume.
Number of physical extents allocated to the logical vol‐
ume.
The number of stripes.
If this field is 0, then the logical
volume is not striped.
The size of each stripe in kilobytes (KB).
Bad block relocation policy.

Compact Listing (-F Option)
The option generates a compact
and parsable listing of the
command output in colon sepa‐
rated fields formatted as
value...]. The option is
designed to be used by
scripts. The resulting com‐
mand output may be split
across multiple lines. The
output may include new keys
and/or values in the future.
If a key is deprecated, its
associated value is set to For
the current version of the
command, the lines format is:
The format of Line 1 is as
follows:
lv_name=value:vg_name=value:lv_per‐
mission=value:lv_sta‐
tus=value: mir‐
ror_copies=value:con‐
sistency_recov‐
ery=value:sched‐
ule=value:
lv_size=value:cur‐
rent_le=value:allo‐
cated_pe=value:stripes=value:
stripe_size=value:bad_block=value:allo‐
ca‐
tion=value:used_pv=value:
io_timeout=value
The format of Line 2 is as
follows:
pv_name=value:le_on_pv=value:pe_on_pv=value
The above line may be repeated
with different values.
The format of Line
n is as follows:
le=value:pv1=value:pe1=value:sta‐
tus_1=value[:...:pvN=value:peN=value:
status_N=value]
The above line may be repeated
with different values.
EXTERNAL INFLUENCES
Environment Variables
determines the language in
which messages are displayed.
If is not specified or is
null, it defaults to "C" (see
lang(5)).
If any internationalization
variable contains an invalid
setting, all internationaliza‐
