Storage Foundation for Windows organizes disks into disk groups. Disk groups provide a way of organizing disks in a system and simplifying storage management for systems with large numbers of disks. They also allow disks to be moved between computers to easily transfer the storage between computers.

All basic and dynamic volumes are required to be in a disk group. There is only one disk group for basic disks, known as the basic group. There can be one or more dynamic disk groups, which are known as dynamic groups. Disks within a dynamic group share a common configuration. Dynamic volumes are created within a dynamic group and are restricted to using disks within that group.

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. Volumes can only be created on disks that belong to disk groups.

A collection of disks that 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 and an internally defined unique ID. The root disk group (rootdg) is a special private disk group.

A collection of disks that share a common configuration. 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 disk group names <code>bootdg</code> (an alias for the boot disk group), <code>defaultdg</code> (an alias for the default disk group) and <code>nodg</code> (represents no disk group) are reserved.
