Service Processor Operational Phases
This section provides a high-level flow of the phases of the Service Processor (SP).
SP Power Applied
Pre-Standby Phase
Standby Phase SP Menus Available
Bring-Up Phase SMS Menus Available
Runtime Phase SMS Menus Available
Pre-Standby Phase:
This phase is entered when the server is connected to a
power source. The server may or may not be fully powered on. This phase is exited
when the Power-On Self Tests (POSTS) and configurations tasks are completed.
The Pre-Standby phase components are:
Ÿ
SP Initialization
SP performs any necessary hardware and software initializations.
Ÿ
SP POST
SP conducts Power-On Self Tests on its various work and code areas.
Ÿ
SP Unattended Start Mode Checks
To assist fault recovery. If unattended start mode is set, the SP automatically
reboots the server. SP does not wait for a user-input or power-on command, but
moves straight through the phase and into the Bring-up Phase. The unattended
start mode can be reset by accessing SMS menus, or SP menus.
