Chapter 2 Using SystemGuard

This chapter introduces the SystemGuard service processor which is included in all Symmetric Multiprocessor models.

Introduction

SMP servers include a service processor, called SystemGuard, as a standard feature. SystemGuard continually monitors the hardware as well as the operating system. If, for

instance, a CPU fails, the system detects this, reboots itself automatically and runs the built-in diagnostics on the hardware. If the CPU is detected as bad during the initial program load (IPL) or reIPL, the CPU is disabled. Likewise, if memory is detected as bad during IPL or reIPL, it is disabled.

SystemGuard allows diagnostics and maintenance to be performed either locally or remotely. The SystemGuard processor makes it possible for these remote systems to be managed from a central location. SMP servers can even be set up to automatically call a Service Center if they fail to boot successfully.

The main features of the SystemGuard are:

• Initialization process flow management

• Local as well as remote control of the system (turning power on or off, diagnostics,

reconfiguration, maintenance)

• Console mirroring to make remote actions visible and controllable by the customer

• Dial-out to a support center in case of system boot failure

• Run-Time surveillance

Using SystemGuard

2-1

Page 36

SystemGuard Power

SystemGuard has its own DC power boundary. This means that even if the system power is off (power button of the system in the off position), SystemGuard is still powered on, as long as the CPU enclosure still has power. This allows control of the system even though the system is down. The only way to turn off the SystemGuard power is to remove the power from the CPU enclosure. When starting the entire system, remember to start the expansion cabinet first if one is connected.

SystemGuard Components

SystemGuard introduces new hardware and firmware components:

• a microprocessor called the Bring-Up MicroProcessor (BUMP)

• a Flash EEPROM

• a Backup EPROM that enables the system to boot in case of a Flash EEPROM failure.

Part of the SystemGuard firmware is stored in the BUMP EPROM; part is in the Flash EEPROM. The Backup EPROM contains a subset of the Flash EEPROM .

SystemGuard Bring-Up MicroProcessor Overview

The SystemGuard Bring-Up MicroProcessor (BUMP) controls the system when the power is off or the AIX operating system is stopped. SystemGuard performs the following:

• Controls the power-on (PON) tests, the power-on self tests (POST) and loading of the AIX operating system.

• Responds to local or remote BUMP console commands to set the mode or set system parameters.

• Runs the SystemGuard programs using the STANDBY MENU or the MAINTENANCE MENU.

• Monitors the “heartbeat” from AIX, if the feature is enabled and AIX is running.

SystemGuard releases control of the system to the AIX operating system after it is loaded. If the AIX operating system stops or is shutdown, SystemGuard again controls the system.

The BUMP console (attached to S1 port) provides the normal input. The service console (attached to S2 port) provides remote service access to the BUMP. Access to both of these consoles is controlled by flags.

SystemGuard Phases

During boot up, SMP servers go through five different phases: Stand-By, Init, Maintenance, Boot, and Run-Time.

Stand-By Phase

The Stand-By phase is present anytime the system unit power is off, and the SystemGuard power is on.

At this phase, the AIX operating system is not yet loaded; the system unit power is not on, and the word Stand-By is displayed on the Operator Panel display.

The SystemGuard is active, and it can receive commands from the BUMP console or Service Console (either local or remote). You can enter the SystemGuard Stand-by menu from this phase.

The Stand-By phase ends when the power button on the Operator Panel is pressed and a power-on command entered.

2-4 Service Guide

Page 39

Init Phase

Init phase is entered when the power button on the Operator Panel is pressed on or when the power command is entered on the BUMP Console or Service Console.

If the System Key is in Normal mode, the BUMP runs the built-in or resident power-on (PON)-tests on the CPU module hardware, IPLs on the first available processor, runs the functional power on self-tests (POST) on the I/O subsystem to check the system, and finally loads the AIX operating system.

If the System Key is in Service mode, and if several conditions are met, the system loads the SystemGuard MAINTENANCE MENU. These conditions are: the Autoservice IPL flag disabled, the BUMP console enabled, and a Valid Service Contract.

If the System Key is in Secure mode, the system enters the Stall state, and the LCD displays the three-digit code 200. The initialization of the system stops until the Physical Key is set to Normal or Service. The Stall state is exited, and control of the system is passed to AIX.

Maintenance Phase

The maintenance phase is entered from the Init phase if the system key is in service mode. If the BUMP console present flag is set, the MAINTENANCE MENU is displayed on the

BUMP console, and the system waits for an operator action. The maintenance menu choices are described on page 2-21. Various maintenance tasks can be performed from this menu. When maintenance tasks are complete, the system can be booted, powered down, or reset.

Boot Phase

SystemGuard enters the Boot phase from either the Init phase or the Maintenance phase. In this phase the system is initialized and control of the system is passed to the operating system. Control of the two serial ports is switched to the operating system and the Run-Time phase is entered. If a valid boot block is not found and the system key is set to Service, SystemGuard returns to the Maintenance phase.

Run-Time Phase

This is the phase where the AIX operating system is in control of the system. The Run-Time phase is entered once the AIX operating system is loaded and takes control of the consoles.

When AIX is stopped again, for example due to a shutdown, the system goes back to the Stand-By phase.

Phase Change (Stand-By to Init)

The phase change from Stand-By to Init is called Crossing The Power boundary. This is achieved by pushing the power button on the Operator Panel or by typing the keyword power at the Stand-By prompt (>). Note that if you type power while the power button is not pushed in, nothing happens until you press the power button. In this case, the power command has been taken into account by SystemGuard, and you don’t have to reenter it. The power command is the default power on command sequence, which you can change from the maintenance menu or AIX service aids.

SystemGuard, checks for a special downloadable diskette (if in Service mode), checks the Flash EEPROM, and then produces an output. The following is an example of what appears:

BUMP FIRMWARE – February 16, 1995 ID 07.01 – POWER_ON in EPROM # FLOPPY NOT READY! DO YOU WANT TO UPDATE FLASH FROM LINE S2[y/n]? n

BUMP FIRMWARE – May 19, 1995 ID xx.xx – POWER_ON in FLASH PROM

The message FLOPPY NOT READY! means that there is no specific downloadable diskette in the diskette drive.

Note: This message is only displayed when IPLing in Service mode. The special diskette could be:

• Code to be downloaded into Flash EPROM

• Code to change the VPD in the EEPROMs of the SMP system

Power-on (PON) Tests

PON tests are run by SystemGuard whenever the system power comes on. There are two types of tests:

• A comprehensive set of tests are performed on the processors, cache, memory and

related hardware when the Fast-IPL flag is disabled.

• A minimum core set of tests are performed on the processors, cache, memory and

related hardware during fast-IPL which cannot be turned off.

Following is an example of PON test output for the Fast-IPL type of test.

CPU FIRMWARE – August 4, 1994 Processor 0 on IPL INIT

Processor 0 on IPL Start

A flashing 888 is displayed if PON tests cannot start. If the PON test hangs, a three-digit code corresponding to a failed component is displayed.

Note that the system IPLs on the first available physical processor. If for any reason processor 0 is not available, the system IPLs on processor 1, and then on 2 so on until a processor is available. If all the processors are disabled, the PON test fails, and SystemGuard treats this as a hardware component failure and goes into the MAINTENANCE MENU in Service mode. In Normal mode, the PON test initiates dial-out, if possible, and goes into Stall state afterward. No IPL proceeds. Processors can be manually enabled again in Service mode through the MAINTENANCE MENU. This can also be repaired locally by:

• Turning the system power off

• Moving the Physical Key into Service position

Using SystemGuard

2-7

Page 42

• Enabling at least one processor from the STAND-BY MENU

There are other resident PON tests to check other system resources. These tests are a subset of the SystemGuard maintenance offline tests, and reside within the flash EEPROM. These tests are divided into the following groups:

BUMP Quick I/O Test Group

These tests check the accessibility and the functions of the standard and direct I/O components from the BUMP: Async lines (S1, S2, and S3), EEPROMs, NVRAM, Flash EEPROM, and TOD (Time-Of-Day).

JTAG (Joint Tests Action Group) Test Group

These tests check the chip-to-chip connections using the JTAG features.

Direct I/O Test Group These tests check the accessibility of the Standard and Direct I/O

components from the CPUs: IONIAN, NVRAM access, EPROM access, TOD, and the diskette.

CPU Test Group These tests are performed by all of the processors and check the

status of the CPU cards: processor, address translation, L1 and L2 caches.

DCB (Data CrossBar) and Memory Test Group

These tests check the status of the system planar and memory cards: data/address lines accessibility, memory components, ECC, memory refresh (CPU checkstop).

Interrupt Test Group These tests collectively check the interrupt system: BUMP-CPU,

CPU-CPU (CPU checkstop).

MCA Test Group Not applicable CPU Multiprocessor Test Group

These tests check the multiprocessor mechanisms, atomic instructions, cache coherency, main memory sharing, and multi-resources sharing.

C Bus Test Group

The following is an example of the output when running these PON tests:

*************** * PON TESTS * *************** .. Bump [01.01.00] DEBUG LINE TEST OK .. Bump [01.02.00] S1 ASL (BUMP) TEST OK .. Bump [01.03.01] S2 ASL (REM.) TEST OK .. Bump [01.04.00] S3 ASL (SPE.)

Phase Change (Init to Maint)

The maintenance phase is entered from the Init phase if the system key is in service mode. If the BUMP console present flag is set, the MAINTENANCE MENU is displayed on the

Phase Change (Maint to Boot)

SystemGuard enters the Boot phase from either the Init phase or the Maintenance phase. In this phase the system is initialized and control of the system is passed to the operating system.

Phase Change (Boot to AIX Load and Run-Time)

Similar to the entry into the Init phase, there is a distinct line when entering this phase. At this line, SystemGuard gives up control of the system and passes it to the loaded code (AIX). This is indicated by the three-digit code 299 on the consoles and Operator Panel.

Since SystemGuard is also giving up control of the two serial lines, nothing can be displayed on the consoles. The usual three-digit boot indicators are still displayed on the Operator Panel. Note that the code 570 virtual SCSI devices being configured can take several minutes for each card in the SMP system.

When the boot indicators have reached c33, AIX has progressed enough to display its own boot messages on the system console. However, this is no longer the SystemGuard Console; it is the AIX console.

SystemGuard Parameters and Flags

A certain number of SystemGuard parameters and flags can be changed through different SystemGuard menus, from the Diagnostics interface and from AIX. Basically, there are four different groups of flags:

Service contract flags These flags enable Service Console usage, maintenance usage

and determine if dial-out messages are sent to IBM or to a Customer Service Center. These flags are stored in the SID (System Identification) field of the System EEPROM.

Diagnostics flags These flags are used to control the service, diagnostics and

maintenance from a customer point of view. For example, the customer can modify one of these flags to authorize setting the Electronic Key from the Service Console or to authorize the dial-out.

Modem and Site Configuration flags

These flags allow the customer to customize modem configuration for the Service Console.

Phone numbers flags These are the dial-in and dial-out phone numbers and the operator

voice number.

Working with SystemGuard

SystemGuard parameters and flags may be changed from different locations. They can be changed from the SystemGuard STAND-BY MENU, the SystemGuard MAINTENANCE MENU, the Diagnostics interface, and also from AIX.

When the key signal is received, SystemGuard clears the screen and displays the SystemGuard prompt. At this point, a keyword can be entered. The supported keywords are:

power This keyword starts the system, exactly as if the power button is pushed.

You can change, disable or enable this keyword: see “Power-On Command Parameters” on page 2-33 for details. Turning the system power on makes the system enter the init phase. Thus, if the Key Mode Switch is in the Service position, and if the

When the system is in Stand-By mode and the System Key (Physical or Electronic Key) is in Service mode, the STAND-BY MENU can be accessed and SystemGuard executed.

If you turn the system unit power on from Stand-By mode with the System Key in the Normal position, the system boots to AIX Multi-User.

If you turn the system unit power on with the System Key in the Service position, you can go to the MAINTENANCE MENU or to Diagnostics, depending on the state of three flags: SystemGuard Console Present, Autoservice IPL, and Service Contract Validity.

If you power on the system with the System Key in Secure, the system stalls. Here is some information on the meaning of the different flags:

BUMP Console Present flag

When the BUMP console is enabled, the LED codes and System Guard messages are displayed on the console during the Init phase. If the BUMP console is not enabled, it is like a regular system; no codes and no messages are displayed on the console during the Init phase. Only AIX messages appear when the system starts loading AIX.

Note that if you are running the level 5 of the SystemGuard firmware, the BUMP Console is disabled by default, and if you enable it, it is disabled after every shutdown. If your system is in Service mode, you might go to Diagnostics instead of Maintenance due the SystemGuard Console being disabled by default.

If you are running level 7 or higher of the SystemGuard firmware, the BUMP Console is enabled by default and stays enabled after a shutdown.

Autoservice IPL flag

Service Contract flag

SystemGuard Menus

SystemGuard menus are low-level menus; they make extensive use of abbreviations or acronyms. Refer to the glossary on page X-1 for a full list of these acronyms and abbreviations.

SystemGuard is menu-driven, and menu choices are usually numbered. Letters are sometimes used and can be entered in either lowercase or uppercase (SystemGuard is case insensitive). The letter x is often used to exit the current menu and return to the previous menu (or leave SystemGuard, if given from the main menu). Commands are only treated after you press the Enter key. Until you press the Enter key, you can use the Backspace key to edit a command. If you enter a command that does not match the available options, a beep signals that an invalid selection has been made.

If enabled, this flag means that you want to go to Diagnostics when booting with the System Key in Service mode.

This flag is preset at the factory and is not variable. The Service Contract is always valid. This flag allows the service center to access the system and do some maintenance. The Service Contract is set by default to an unlimited number of days (exactly 32767 days).

and parameters (set during manufacturing), see the table in “Default Parameter Values” on page B-1 of the service guide for your system. The following flags can be managed:

• Remote Authorization: Only the local operator can enable this flag to enable remote maintenance to be performed. Both the local and remote operators can disable it.

• BUMP Console Present: If enabled, SystemGuard displays the MAINTENANCE MENU on the BUMP console (line S1). If disabled, the MAINTENANCE MENU is not available on the BUMP console.

• Autoservice IPL: When enabled, this flag enables an automatic IPL even if the Key Mode Switch is in the Service position, thus avoiding the display of the MAINTENANCE MENU.

• Extended Tests: This parameter determines under what conditions extended power on self-tests are run at IPL time, after the regular power on self-tests (POSTs). If the parameter is enabled, the extended tests are run. If the parameter is disabled, the extended tests are not run.

• Power-On Tests in Trace Mode: When enabled, supports the running of POST tests in

trace

mode, which gives extra information about how tests are conducted. A dedicated tty

line is required, this is to be used only when directed by service support personnel.

• Power-On Tests in Loop Mode: When enabled, SystemGuard loops on the POST tests and does not IPL.

• Fast IPL: When enabled, the long POST tests are not run, shortening the INIT phase. This feature lets you start the machine quickly, when the test performance is not necessary. This flag is not permanent. It only remains set until the next IPL, at which point it is automatically cleared.

• Set Electronic Mode Switch to Normal: This command sets the Electronic Mode Switch to the Normal position. Keep in mind that the Electronic Mode Switch is only taken into account if the Key Mode Switch is in the Normal position. The Electronic Mode Switch is also set to Normal each time the Key Mode Switch is moved.

Set Unit Number

Use this option to assign logical numbers to units that you add to your system. Whenever a new unit is added, this command must be run to update the unit configuration

table. Simply enter 2 in the main STAND-BY MENU to select this option. The process of assigning

a unit number is automatic: there is no need to pick a number. An RS-485 bus interconnects all system and expansion units, each being addressed using a

logical number of 0 or 1. The base unit, where the SystemGuard and the operator panel are present is the master of the RS-485 bus, and is always given logical number 0. The first expansion unit is assigned the logical number 1.

Some Common SystemGuard Tasks

The following tasks are done through the STAND-BY and MAINTENANCE MENUs that are part of SystemGuard. Note that these tasks can also be carried out from AIX diagnostics.

How to Set the Electronic Key

The key can be set electronically, making it easier to provide remote support without physically touching the machine. You can do this from the Stand-By mode or from AIX.

Setting the Electronic Key from Stand-By Mode

1. Go into Stand-By mode.

2. Press the Enter key to get the prompt displayed (>).

3. Press the Enter key again. The cursor (in block mode) is then superimposed on top of the prompt.

4. At this point, press the Escape key and then the s key. This turns the Electronic Key to Service even though the Physical Key is still in Normal position.

5. Press the Enter key again.

6. Enter the keyword, sbb (Stand-By BUMP). You should see the STAND-BY MENU appear; this is a way to check that the System Key is in Service.

7. Exit from the STAND-BY MENU.

At this step, if you want to go back to Normal, press the Enter key again; then press the ESC-n key. This puts the Electronic Key to Normal position.

Setting the Electronic Key from AIX

1. While AIX is running, log in as user root.

2. Type the following command to look at the current status of the Electronic Key:

keycfg –d

3. To change the key to Service, type the following command:

keycfg –c service

4. To change the key to Secure, type the following command:

keycfg –c secure

5. To change the key back to Normal, type the following command:

keycfg –c normal

Note that, each time, you can run the keycfg –d command to verify the status of the key.

Displaying Configuration through the Maintenance Menu

The system configuration can also be displayed through the MAINTENANCE MENU. You will find the same kind of information displayed previously, but in a different and more readable way.

To get the system configuration from the MAINTENANCE MENU, do the following:

1. Enter the MAINTENANCE MENU.

2. Enter 0 to select DISPLAY CONFIGURA TION.

The configuration display is a good picture of the SystemGuard configuration on one screen. Here is an example:

How to Set the Service Line Speed

By default, the service line speed is 1200 baud or 2400 baud depending on the level of SystemGuard. This speed can be changed through the SystemGuard MAINTENANCE MENU. In order to use the Service Console properly, the terminal connected to the S2 connector has to be set to the same speed. This speed is not necessarily the same as the speed defined in AIX for tty1. To avoid changing the speed of the terminal itself when AIX is running, it is more convenient to have the same speed for the Service Console and tty1 defined in AIX.

Setting Line Speed through the Maintenance Menu

1. Enter the MAINTENANCE MENU.

2. Enter 8 in this menu to select the SET PARAMETERS menu.

How to Set Up Console Mirroring

Console Mirroring Concepts

Console mirroring is a way to provide the customer a view of what the person working remotely from the Service Console is doing on the system. When mirroring is active, the Service Console and the BUMP Console are logically identical, and both are tty0 (tty1 is disabled when the mirroring starts).

Mirroring only works on the two serial ports, S1 and S2, and their respective ASCII consoles or terminal emulators. It does not work on the graphical devices. The BUMP Console can be either local (no modem connected) or remote (through a modem connection). Remote console connection must be established through dial-in (BUMP does not dial out). The Service Console is usually remote, connected through a Hayes-compatible modem on the S2 port; however a local, directly attached console at the S2 port can also be supported.

Modem

Remote Support Center

When mirroring is active, the customer on the BUMP Console and the support personnel on the Service Console both see the same output on their screens, and either one may enter characters. One person can even start typing and the other finish it. For example, the support personnel may log in as root on the Service Console, and the customer may enter the root password on the BUMP Console. Therefore, the remote support personnel do not need to know the root password.

Modem

Customer Site

System Unit

Console mirroring is possible during the following SystemGuard phases: Stand-By, Init and Run-Time (AIX running).

The prerequisites for console mirroring are:

• Remote Service Support 1

• /usr/share/modems/mir_modem file present (for mirroring when AIX is up)

2-44 Service Guide

Page 79

Setting Up Console Mirroring

In order to setup console mirroring, you need first to authorize the Service Console, and set up the right line speed. Refer to previous chapters on how to set up the service line speed and how to authorize the Service Console. Then do the following:

1. While AIX is running, log in as user root.

2. Type the following command to make sure that the Service Contract Validity is greater than or equal to 0:

mpcfg –dS

The command output is:

Index Name Value 1 Remote Service Support 1 2 Quick On Call Service 0 3 Service Contract Validity 32767 4 Service Support Type

Note that mirrord cannot be started if the Service Contract Validity is –1 (No Valid Service Contract).

3. Wake up the mirror daemon (mirrord) by either switching the Physical Key to Service or by typing the following command:

keycfg –c service

If mirrord is awakened successfully, you should see the following messages:

mirrord: Wait connection... mirrord: Remote user connected, mirroring active

4. Type the following command to verify that mirrord is running:

ps –ef|grep mir

The command output is similar to the following:

root 2308 1 0 12:08:21 – 0:00 /usr/sbin/mirrord mir_modem root 6212 4552 3 12:21:58 0 0:00 grep mir

5. Now, the support personnel should be able to work on the remote console, and the customer should be able to watch on the BUMP Console what the service personnel enter on the Service Console.

6. To turn mirroring off, either switch the Physical Key to Normal or type the command:

keycfg –c normal

You should see the following message:

mirrord: mirroring is stopped

If the prerequisite conditions are met, the mirrord daemon is started at boot time, but goes to sleep until the System Key is set to Service. When mirrord is awakened, it kills all processes on S2 and pushes the streams mirror module onto the S2 queue.

Since it is assumed that the Service Console is remote, mirrord requires a modem file that specifies the type and characteristics of the modem. This modem file is required even if the Service Console is connected locally without modem. Thus, a file with no modem must be provided. The default name of the modem file is mir_modem. Please refer to the appendix for supported modem files.

How to Enable Surveillance

Surveillance is implemented by the survd daemon. This daemon, when started, establishes a heartbeat between AIX and SystemGuard. In case of an AIX hang, SystemGuard detects it and reboots the system.

To implement the surveillance, do the following:

1. Enter:

survd –d {number of seconds} This starts the survd daemon, thereby starting the surveillance. The number of

seconds determines the heartbeat delay time, where ten seconds is the minimum, and

the default is sixty seconds.

2. Carry out this step if you want a hardware reboot: survd –h (–h flag sets hardware reboot)

3. To turn off the surveillance, type the following command:

survd –r

Attention: If you issue the command kill –9 <survd_proc_id>, the system reboots because SystemGuard thinks that AIX hung since it no longer receives a heartbeat.

How to Set Up the Dial-Out Feature

The dial-out feature can be implemented, either through SystemGuard or AIX.

Setting Up Dial-Out from SystemGuard

The dial-out feature is the automatic sending of certain errors to a service center. The customer must set the Dial-Out Authorization flag. When the Physical Key is in the Normal position, if a boot fails due to a POST error or boot device not found, a problem report is sent to the remote service center.

The prerequisites for the dial-out feature are:

• Remote Service Support flag enabled (1)

• Remote authorization enabled (1)

• Dial-out authorization enabled (1)

The dial-out feature uses the dial-out phone numbers listed in SystemGuard configuration. To add or change phone numbers, do the following:

1. Enter the SystemGuard MAINTENANCE MENU.

2. Enter 8 from this menu to select the SET PARAMETERS menu.

3. Enter 3 from the SET PARAMETERS menu to select the PHONE NUMBERS menu.

4. Select your option, and enter the dial-out number or numbers. There are two service center and customer hub numbers. These relate to primary (1) and secondary (2) numbers.

2-46 Service Guide

Page 81

Modem Configuration

The modem on line S2 must be configured using an ASCII modem configuration file which describes various parameters using a specific syntax. AIX uses this file directly. SystemGuard uses the same information (in condensed form) stored in non-volatile memory (NVRAM).

The modem line speed must be correctly set, either by using SystemGuard (see “Miscellaneous Parameters” on page 2-35 or the diag command. The modem configuration is used by both the dial-out and dial-in services.

The following table lists the data that SystemGuard sends to the remote support center.

Booting from an SCSI Device through the Bootlist

The system can be booted from an SCSI device, such as a tape drive, without going through the MAINTENANCE MENU. In this case, it uses the bootlist to determine the boot device while in Service mode. The bootlist can be updated through Service Aids in Diagnostics.

Following are the prerequisites for booting from an SCSI device (a tape drive for example) in Service mode:

• The Autoservice IPL flag must be enabled.

• The Service mode bootlist must be updated (this can be done in AIX Diagnostics by

selecting Service Aids and Display/Alter Bootlist).

• A supported SCSI device, such as a tape drive.

• A bootable SCSI media, such as a bootable tape (install or mksysb).

To boot off this SCSI device, do the following:

1. Switch the System Key to Service.

2. Insert the bootable media in the SCSI device.

3. Turn on the system power.

The system then boots up from this SCSI device. If the boot up is not successful, verify that the tape is bootable, or clean the media device.

Enabling/Disabling Processors through AIX

The processors can be disabled/enabled through AIX as well. This is done through the cpu_state command. Following is the command with various options:

• To list the processors and view their statuses, type cpu_state –l. The output should

look something like this:

Name Cpu Status Location proc0 0 enabled 00–0P–00–00 proc1 1 enabled 00–0P–00–01 proc2 2 enabled 00–0Q–00–00 proc3 3 enabled 00–0Q–00–01

• To disable a CPU, CPU1 for example, type cpu_state –d 1. Look at the result with

cpu_state –l:

Name Cpu Status Location proc0 0 enabled 00–0P–00–00 proc1 1 disabled 00–0P–00–01 proc2 2 enabled 00–0Q–00–00 proc3 3 enabled 00–0Q–00–01

Note: This change does not take effect until after a reboot. After a reboot, the cpu_state

–l command shows:

Name Cpu Status Location proc0 0 enabled 00–0P–00–00 proc1 – disabled 00–0P–00–01 proc2 1 enabled 00–0Q–00–00 proc3 2 enabled 00–0Q–00–01

Phone Numbers

If remote maintenance is used, SystemGuard requires several phone numbers to be entered. Additional information is provided in “Phone Numbers” on page 2-34.

Service Line Speed Parameters

If remote maintenance is used, SystemGuard requires that the line speed be configured. The default is 1200 baud. The speed can be set by MISCELLANEOUS PARAMETERS menu or the Service Aids.

Modem Parameters

If remote maintenance is used, SystemGuard may require that the Modem Parameters file be updated. This file can be set by the Service Aids.

Passwords

Passwords are used to protect access to SystemGuard. The passwords are the Maintenance Password and the Customer Maintenance Password. No passwords are set at the factory. However, they can be customized for your needs. The Maintenance Password restricts access to basic features of the MAINTENANCE MENU. If you set the password you should provide it to your service personnel when requested. The Customer Maintenance Password restricts access to sensitive customer data. If you set the password you normally should not provide it to your service personnel. The passwords can be set from the MISCELLANEOUS P ARAMETERS menu.

Reloading the Flash EEPROM

Follow this procedure to load a new version of SystemGuard into the flash EEPROM. Only system administrators should perform this procedure.

Prerequisites

To install a new version of the EEPROM firmware, you need either a firmware diskette containing a binary firmware image, or a file containing the firmware.

You can also update the firmware using a file containing a new firmware version.

Updating the Flash EEPROM (using a firmware diskette)

If the system is not yet powered on, simply insert the firmware diskette in the drive, place the Mode Switch in the Service position, and then power on the system. The firmware diskette is identified by a special header which distinguishes it from diskettes containing other data. The existing firmware recognizes the special header and automatically loads the new firmware version.

If AIX is already up and running (the run-time phase), reloading the firmware requires more steps, because you first have to shut down the system, then reboot the machine as described in the preceding paragraph.

Updating the Flash EEPROM (using a file)

An administrator with root authority can use the AIX diag command to update the EEPROM firmware using a file. Because this procedure reboots the machine after the update, the root user who performs this procedure should be the only logged user. If the system is not yet powered on, power on the system, and log in as the root user without letting other users log in. Then follow the steps to use when the system is up and running.

If AIX is already up and running (the run-time phase), perform the following steps:

1. Make sure that no other users are logged in to the system (log them out if necessary).

2. Make sure that you have root authority (use the su command if necessary).

3. Enter the diag command or load diagnostics when the Key Mode switch is in the Service position.

4. Select Service Aids.

5. Select the

DANGER

An electrical outlet that is not correctly wired could place hazardous voltage on metal parts of the system or the products that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.

Before installing or removing signal cables, ensure that the unit main switch is set to off or the power cable is unplugged for the system unit and all attached devices are unplugged.

When adding or removing any additional external devices to or from the system, ensure that the power cables for those devices are unplugged before the signal cables are connected. If possible, disconnect all power cables from the existing system before you add a device.

Use one hand, when possible, to connect or disconnect signal cables to prevent a possible shock from touching two surfaces with different electrical potentials.

During an electrical storm, do not connect cables for display stations, printers, telephones, or station protectors for communication lines.

CAUTION: This product is equipped with a 3-wire power cable and plug for the user’s safety. Use this power cable in conjunction with a properly grounded electrical outlet to avoid electrical shock.
