Using the Service Processor and Service Director Features
The Service Processor and Service Director features protect users against unnecessary
system downtime by keeping support personnel (both internal and external) aware of
any unexpected changes in the system environment. In combination, the two features
provide a flexible solution to automated system maintenance.
Service Processor
The Service Processor runs on its own power boundary and continually monitors
hardware attributes, the AIX Operating System, and the environmental conditions within
the system. Any system failure which prevents the system from coming back to an
operational state (a fully functional AIX Operating System) is reported by the Service
Processor. The Service Processor is controlled by firmware and does not require the
AIX Operating System to be operational to perform its tasks. If any system failures are
detected, the Service Processor has the ability to take predetermined corrective actions.
The methods of corrective actions are:
v Surveillance
v Call Home
v AIX Operating System Monitoring
Surveillance is a function in which the Service Processor monitors the system through
heartbeat communication with the system firmware. The heartbeat is a periodic signal
that the firmware can monitor. During system startup, the firmware surveillance monitor
is automatically enabled to check for heartbeats from the firmware. If a heartbeat is not
detected within a default period, the Service Processor cycles the system power and
attempts to restart until the system either restarts successfully, or a predetermined retry
threshold is reached. In the event the Service Processor is unsuccessful in bringing the
system online (or in the event that the user asked to be alerted to any Service
Processor assisted restarts), the system can call home to report the error.
