Service processor menus are available on ASCII terminals attached to serial port S1.
Bring-up phase
This phase is entered upon power-on, and exited upon loading of the operating system.
The bring-up phase components are as follows:
v Retry Request Check
The service processor checks to see if the previous boot attempt failed. If the specified number of
failures are detected, the service processor displays an error code and places an outgoing call to notify
an external party if the user has enabled this option.
v Dial Out
The service processor can dial a preprogrammed telephone number in the event of an IPL failure. The
service processor issues an error report with the last reported IPL status indicated and any other
available error information.
v Update Operator Panel
v Environmental Monitoring
The service processor provides expanded error recording and reporting.
v System Firmware Surveillance (Heartbeat Monitoring)
The service processor monitors and times the interval between system firmware heartbeats.
v Responding to System Processor Commands
The service processor responds to any command issued by the system processor.
Runtime 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 (on some servers).
v Responding to System Processor Commands
The service processor responds to any command issued by the system processor.
v Run-Time Surveillance
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.
