Cur LVCurrent number of logical volumes within the volume group. 

Open LVNumber of logical volumes within the volume group that are currently open. 

Max PVMaximum number of physical volumes allowed in the volume group. 

Cur PVCurrent number of physical volumes within the volume group. 

Active PVNumber of physical volumes that are currently active. 

PE SizeSize of each physical extent. 

Max PE per PV
Maximum number (limit) of physical extents that can be allocated from any of the physical volumes in the volume group.

VGDANumber of volume group descriptor areas within the volume group. 

Total PETotal number of physical extents within the volume group: this is the sum of the number of physical extents belonging to each available physical volume in the volume group. 

Alloc PENumber of physical extents currently allocated to logical volumes. 

Free PENumber of physical extents not allocated.
