Standby Phase SP Menus Available
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.
