Disk Set Examples

For an example of a disk set, consider two hosts with six disks each. Host A owns disk set "blue" with three disks, while Host B owns disk set "red", also with three disks. Both hosts have physical access to both disk sets, and each disk appears as the same major/minor numbers and c*t*d* names on each system.

Either host can release the set it owns, or can take the other set, so both hosts can non-concurrently share access to those disks. With high-availability software, such as Sun Cluster, the disk ownership could automatically fail over to the second host if the first fails.
