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
