• it contains two plexes named vol06-01 and vol06-02
• each plex contains one subdisk
• each subdisk is allocated from a different VM disk (disk01 and
disk02)
Connection Between Volume Manager Virtual Objects
Volume Manager virtual objects are combined to build volumes. The
virtual objects contained in volumes are: VM disks, disk groups,
subdisks, and plexes. Volume Manager objects have the following
connections:
• Volume Manager disks are grouped into disk groups
• one or more subdisks (each representing a specific region of a disk)
are combined to form plexes
• a volume is composed of one or more plexes
The example in Figure 1-7, Connection Between Volume Manager
Objects, shows the connections between Volume Manager virtual objects
and how they relate to physical disks. Figure 1-7, Connection Between
Volume Manager Objects, shows adisk group with two VM disks(disk01
and disk02). In disk01, there is a volume with one plex and two
subdisks. In disk02, there is a volume with one plex and a single
subdisk.
