Logical View of the LVM

Terminology:

Volume Group (VG)

A set of one or more PVs which form a single storage pool. You can define multiple VGs on each AIX system.

Logical Partition (LP)

A logical mapping to one or more PPs within the same VG, regardless of whether they're on the same PV or not.

Logical Volume (LV)

A set of one or more LPs within the same VG which form a usable unit of disk space. LVs are used analogously to partitions on PCs or slices under Solaris: they usually contain filesystems or paging spaces ("swap").
