Abstract
An automatic recovery system for a network appliance features a watchdog processor that monitors operation of the appliance and initiates reboot as necessary. A primary and a secondary boot partition are provided in the system, in some embodiments on the same mass storage device, and in other embodiments on a different mass storage device. In the event reboot is unsuccessful from the primary boot partition, reboot is initiated from the secondary boot partition. The watchdog processor executes automatic recovery software stored in a non-volatile storage device, which may be a part of the same IC as the watchdog processor.
