Abstract
A high-availability computer system comprises at least two processors, each having its own private disk drive, and a shared disk drive, accessible by both processors. Each of the private disk drives holds system files for establishing a processor as a secondary processor, and the shared disk drive holds system files for establishing a processor as a primary processor. When it boots up, each processor decides whether to use the system files from its private disk so as to become a secondary, or to use the system files from the shared disk so as to become the primary. As as result, after a system failure or reboot, either processor can pick up the characteristics of the the primary processor, and will have all the most up-to-date primary information available to it.
