Run-Time Phase - IBM F80 Service Manual

Run-Time Phase

This phase includes the tasks that the service processor performs during steady-state
execution of the operating system.
v Environmental monitoring
The service processor monitors voltages, temperatures, and fan speeds.
v Responding to system processor commands
The service processor responds to any command issued by the system processor.
v Run-time surveillance (heartbeat monitoring)
If the device driver is installed and surveillance enabled, the service processor
monitors the system heartbeat. If the heartbeat times out, the service processor
places an outgoing call. This is different from the bring-up phase scenario, where the
specified number of reboot attempts is made before placing an outgoing call.
