active spare. Thus, the data on this physical
volume is 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.
Total PE Total number of physical extents on the physical volume.
Free PE Number of free physical extents on the physical volume.
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 physi-
cal volume once it has been repaired (see pvmove(1M)). If it cannot be deter-
mined 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" physi-
cal 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 residing 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.
Autoswitch For multiported devices accessed via multiple paths, this field indicates the
autoswitch behavior for the physical volume (see pvchange (1M)).
On LVM will automatically switch from the path it is
using whenever a better path to the physical
volume is available. LVM will switch paths when a
better path recovers (after it had failed earlier), or
if the current path fails and another path is avail-
able. This is the default.
Off LVM will automatically switch to using the best
available path only when the path currently in use
is unavailable. LVM will continue using a specific
path for the physical volume as long as it works,
regardless of whether another better path recovers
from a failure.
--- Physical volume groups ---
Information about physical volume groups belonging to vg_name:
PVG Name Name of a physical volume group in the volume group.
PV Name The block device path name of a physical volume in the physical volume
group.

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)).
