IBM 6.00E+04, 6C4 manual Bring-Up Phase, Runtime Phase

Bring-Up Phase

The bring-up phase components are as follows:

vRetry 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.

vDial 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.

vUpdate Operator Panel

The service processor displays operator panel data on the HMC virtual terminal window if a remote connection is active.

vEnvironmental Monitoring

The service processor provides expanded error recording and reporting.

vSystem Firmware Surveillance (Heartbeat Monitoring)

The service processor monitors and times the interval between system firmware heartbeats.

vResponding 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.

vEnvironmental Monitoring

The service processor monitors voltages, temperatures, and fan speeds (on some servers).

vResponding to System Processor Commands

The service processor responds to any command issued by the system processor.

vRun-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 are made before placing an outgoing call.

vHMC surveillance

On an HMC-managed system, the service processor monitors the communication link between the managed system and the HMC. If the service processor detects that this communication link has been broken, it will post an error to the operating system running on the managed system.
