Combining Virtual Objects in VxVM
VxVM virtual objects are combined to build volumes. The virtual objects
contained in volumes are VM disks, disk groups, subdisks, and plexes.
Volume Manager objects are organized as follows:
• VM disks are grouped into disk groups
• Subdisks (each representing a specific region of a disk) are combined
to form plexes
• Volumes are composed of one or more plexes
