Disk Sets

A shared disk set, or simply disk set, is a set of disks that contain state database replicas, volumes, and hot spares. This pool can be shared exclusively but not concurrently by multiple hosts.

A disk set provides for data availability in a clustered environment. If one host fails, another host can take over the failed host's disk set. (This type of configuration is known as a failover configuration.) Additionally, disk sets can be used to help manage the Solaris Volume Manager name space, and to provide ready access to network-attached storage devices.
