Chapter 3. Using the Service Processor
Note: The information in this chapter regarding the configuring of serial ports, and
modems attached to those serial ports, applies only to the serial ports (S1 and
S2) on the primary I/O book (location U1.18-P1-H2). None of this information is
applicable to the serial ports, or modems attached to those serial ports, on the
Hardware Management Console for pSeries (HMC).
Note: On some of the system management services (or service processor) screens,
you will see the term

LPAR

, which is equivalent to the term

partitioned system

.
The service processor runs on its own power boundary and continually monitors
hardware attributes and the environmental conditions within the system. The service
processor is controlled by firmware and does not require the AIX operating system to be
operational to perform its tasks.
The service processor menus allow you to configure service processor options, as well
as enable and disable functions.
Service processor menus are available using an HMC virtual terminal window when OK
is displayed on the operator panel or when the service processor has detected a server
problem (such as a surveillance failure).

Service Processor Menus

The service processor menus are divided into the following groups:
vGeneral user menu - the user must know the general-access password.
vPrivileged user menus - the user must know the privileged-access password.
If the server is powered off, the service processor menus can be accessed locally or
remotely on the following:
vSerial port 1 (S1)
vSerial port 2 (S2)
vThe HMC
