Service Processor Operational Phases
This section provides a high-level flow of the phases of the service processor.
SP Power Applied
Pre-Standby Phase
Standby Phase SP Menus Available
Bring-Up Phase SMS Menus Available
Run-time Phase Operating System 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.
Standby Phase
The standby phase can be reached in either of the following ways:
v With the system off and power connected (the normal path), recognized by OK in the LCD display.
OR
v With the system on after an operating system fault, recognized by an 8-digit code in the LCD display.
In the standby phase, the service processor takes care of some automatic duties and is available for
menus operation. The service processor remains in the standby phase until a power-on request is
detected.
The standby phase components are as follows:
v Modem Configuration
The service processor configures the modem (if installed) so that incoming calls can be received, or
outgoing calls can be placed.
v Dial In
Monitor incoming phone line to answer calls, prompt for a password, verify the password, and remotely
display the standby menu. The remote session can be mirrored on the local HMC virtual terminal
window if the system is so equipped and if the user enables this function.
v Menus
