Bring-Up Phase SMS Menus Available

Run-time Phase AIX Login Prompt Available

Pre-Standby Phase

This phase is entered when the system is connected to a power source. The system

may or may not be fully powered on. This phase is exited when the power-on self-tests

(POSTs) and configuration tasks are completed.

The pre-standby phase components are:

v Service Processor Initialization - Service processor performs any necessary hardware

and software initialization.

v Service Processor POST - Service processor conducts Power-on self-tests on its

various work and code areas.

v Service Processor Unattended Start Mode Checks - To assist fault recovery. If

unattended start mode is set, the service processor automatically reboots the system.

The service processor does not wait for user input or power-on command, but moves

through the phase and into the bring-up phase. Access the SMS menus or the

service processor menus to reset the unattended start mode.
