Chapter 7. Using the Service Processor
Notes:
1. 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 IBM Hardware Management Console for pSeries (HMC).
2. 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 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:
v General user menu - the user must know the general-access password.
v
Privileged 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:
v
Serial port 1 (S1)
v Serial port 2 (S2)
v
The HMC
Accessing the Service Processor Menus Locally
Service processor menus can be accessed by opening a virtual terminal window on the HMC, or by
attaching an ASCII terminal to serial port 1 (S1) or serial port 2 (S2). After
OK
displays in the operator
panel, press any key on the keyboard to signal the service.
Note: The service processor menus cannot be accessed simultaneously on a virtual terminal window on
the HMC and on an ASCII terminal. Accessing the menus on the HMC locks out access to the
ASCII terminals and the other way around.
When you gain access, the service processor prompts you for a password (if one is set), and when
verified, displays the service processor menus.
The service processor menu prompt, represented by 0> or 1> , indicates the serial port to which the
terminal is connected.
v
An ASCII terminal can have the following prompts:
–
0>
indicates serial port 1 (S1)
–
1>
indicates serial port 2 (S2)
v
The HMC always indicates
0>
