About disk groups
A disk group is a named collection of disks that share a common configuration.
Volumes and other VxVM objects must be created within a disk group, and are
restricted to using disks from within that disk group.
About LUNs
A LUN, or logical unit, can either correspond to a single physical disk, or to a
collection of disks that are exported as a single logical entity, or virtual disk, by
a device driver or by an intelligent disk array’s hardware. VxVM and other Veritas
software modules may be capable of automatically discovering the special
characteristics of LUNs, or you can use disk tags to define new storage attributes.
Disk tags are administered by using the vxdisk command or the VEA graphical
user interface.
About attributes
A storage attribute allows the properties of a LUN to be defined in an arbitrary
conceptual space.
For example, attributes can describe the following properties:
■ Disk access name
■ Disk media name
■ Manufacturer
■ Model type
■ Physical location, such as rack number, frame number, floor, building, or site
■ Hardware RAID configuration
■ Failover properties
