In combination, the two featuresprovide a flexible solution to automated system maintenance.Service ProcessorThe Service Processor runs on its own power boundary and continually monitorshardware attributes, the AIX Operating System, and the environmental conditions withinthe system. Any system failure which prevents the system from returning to anoperational state (a fully functional AIX Operating System) is reported by the ServiceProcessor. The Service Processor is controlled by firmware and does not require theAIX Operating System to be operational to perform its tasks. If any system failures aredetected, the Service Processor has the ability to take predetermined corrective actions.The methods of corrective actions are:v Surveillancev Call Homev AIX Operating System MonitoringSurveillance is a function in which the Service Processor monitors the system throughheartbeat communication with the system firmware. Theheartbeat is a periodic signalthat the firmware can monitor. During system startup, the firmware surveillance monitoris automatically enabled to check for heartbeats from the firmware. If a heartbeat is notdetected within a default period, the Service Processor cycles the system power andattempts to restart until the system either restarts successfully, or a predetermined retrythreshold is reached. In the event the Service Processor is unsuccessful in bringing thesystem online (or in the event that the user asked to be alerted to any ServiceProcessor assisted restarts), the system can call home to report the error.38 User’s Guide
