LVM: Display basic information about Physical Volumes, Volume Groups and Logical Volumes

# Display information about a Physical Volume within a Volume Group
# ------------------------------------------------------------------------------------------

# The default is to print every known physical volume in the system along with
# its physical disk name, physical volume identifiers (PVIDs), to which volume
# group (if any) the physical volume belongs, and the state of the volume group
# as active if the volume group is varied on or concurrent if it is varied on
# in concurrent mode

# To show the WWID/UUID of a physical volume we can use '-u' option that will give us the
# following informations in columns:

# - Physical disk name
# - Physical volume identifiers (PVIDs)
# - Volume group (if any), or label (if any), belonging to
# - The state of the volume group (Active|Concurrent|Locked)
# - Unique device identifier (UDID)
# - Universally Unique Identifier (UUID)

# PVs: Number of physical volumes used by the logical volume.
# Logical volume state: State of the logical volume. Opened/stale indicates the logical volume is
#   open but contains partitions that are not current. Opened/syncd indicates the logical volume
