27Understanding Veritas Volume Manager
How VxVM handles storage management
■ Subdisks (each representing a specific region of a disk) are combined to form
plexes
■ Volumes are composed of one or more plexes
Figure 1-5 shows the connections between Veritas Volume Manager virtual
objects and how they relate to physical disks. The disk group contains three VM
disks which are used to create two volumes. Volume vol01 is simple and has a
single plex. Volume vol02 is a mirrored volume with two plexes.
