A set of disks that are under VxVM control and share a common configuration. A disk group configuration is a set of records containing detailed information on existing VERITAS Volume Manager objects (such as disk and volume attributes) and their relationships. Each disk group has an administrator-assigned name. The root disk group (rootdg) is a special private disk group that always exists. Volumes can only be created on disks that belong to disk groups.

A disk group configuration is a set of records containing detailed information on existing VxVM objects (such as disk and volume attributes) and their relationships. Each disk group has an administrator-assigned name and an internally defined unique ID. The root disk group (rootdg) is a special private disk group that always exists.

a named collection of disks that share a common configuration
One or more Automatic Storage Management disks managed as a logical unit. Automatic Storage Management disks can be added or dropped from a disk group while preserving the contents of the files in the group, and with only a minimal amount of automatically initiated I/O required to redistribute the data evenly. All I/O to a disk group is automatically spread across all the disks in the group.
