Disk Sets

A shared disk set, or simply disk set, is a set of shared disk drives containing volumes and hot spares that can be shared exclusively but not at the same time by two hosts. Currently, disk sets are only supported on SPARCstorage Array disks.

A disk set provides for data redundancy and availability. If one host fails, the other host can take over the failed host's disk set. (This type of configuration is known as a failover configuration.)
