unavailable/active spare
The physical volume is unavailable and it’s an active
spare. Thus, the data on this physical volume is una-
vailable.
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 infor-
mation 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 ori-
ginally 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 available. This
is the default.
Off LVM will automatically switch to using the best avail-
able path only when the path currently in use is una-
vailable. 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)).
EXAMPLES
Display information about all the volume groups within the system:
vgdisplay
Display all of the information about one volume group, including the characteristics and status of both the
logical and physicalextents of the volume group:
