Abstract
A method, system, and apparatus for reestablishing communications between a host and a service processor after the service processor has ceased to function correctly is provided. In one embodiment, the host exchanges heartbeat signals with the service processor. The heartbeat signals indicate that the service processor is active and functioning. In response to a failure to receive a heartbeat signal or in response to some other indication that the service processor is not performing correctly, the host causes a hard reset of the service processor. In addition, the service processor can detect a failure within itself and initiate a hard reset to itself. After the hard reset, the service processor returns to a monitoring mode without performing initial tests of the data processing system. Furthermore, the data processing system remains active and is not shut down during the hard reset of the service processor.
