the AIX documentation for instructions.

Ø Install application programs

To install application programs, follow the instructions supplied with each

application program.

Chapter 1. System Startup 1-9

1-10 7046 Model B50 User's Guide

Chapter 2. Using the Server

This section provides information on how to start and use the server.

Starting the Server

Perform the following steps to start the server.

1. Turn on all attached devices.

2. Turn on the server.

3. If power does not come on when you turn on the server, ensure that the power

cord, located at the back of the server, is plugged in. If this does not solve the

problem, go to Chapter 8, “Determining Hardware Problems.”

When you turn on the server, the Power LED comes on and the server starts a

POST (power-on self test). During this test, the disk status LED flashes intermittently.

The server beeps a short beep, and progress indicators appear on the operator

panel display (if a display is attached).

 Copyright IBM Corp. 1999

2-1

Console Selection

After the server starts up, you can select the system console for your server if one

has not been chosen before (or if your display adapter configuration has changed).

The system console functions as the primary display and keyboard for your server.

On a graphical display, the console selection screen looks like the following

illustration:

If the console selection screen appears, each display and ASCII terminal attached to

your server appears with a number. To define a display or ASCII terminal as your

system console, press the number on the keyboard that corresponds to the system

console you choose.

If a console is not chosen after a certain amount of time, the server automatically

chooses an ASCII terminal as the system console (whether or not one is installed).

To choose another system console, you must shut down and restart the server.

2-2 7046 Model B50 User's Guide

POST Indicators

If you are using an ASCII terminal (attached to serial port 1), a series of POST

indicators appear on the screen as each subsystem is initialized.

If you are using a directly attached keyboard and a graphical display attached to

a display adapter, then the POST progress indicators appear as icons across the

bottom of the display as follows:

Memory Modules: Tests system memory.

Keyboard: Initializes the keyboard and mouse. When this

icon appears, you can choose one of several different startup

options.

Ÿ Pressing the F1 key or the numerical 1 key activates the

System Management Services.

Ÿ Pressing the F5 key or the numerical 5 key invokes the

default boot list mode, located in firmware.

Ÿ Pressing the F6 key or the numerical 6 key works like the

F5 key or numerical 5 key except firmware looks for a boot

record according to the custom bootlist that was setup by

System Management Services.

Ÿ Pressing the F8 key or the numerical 8 key selects the

Open Firmware Command line.

If any of these keys are pressed, the chosen option occurs

after all of the POST icons appear. If no keys are pressed, the

server boots from the default boot list and starts the operating

system after all POST icons appear.

Network: Initializes network adapters.

SCSI: Initializes SCSI Adapters.

Chapter 2. Using the Server 2-3

Audio: Initializes the audio system. For the audio system to

take effect, any startup option key must be pressed before the

end of audio initialization.

If the POST process stops and indicates an error on the LED or console in any one

of these subsystems, record the error number and refer to Chapter 8, “Determining

Hardware Problems.”

For more information on:

Ÿ The System Management Services (started by pressing F1 or the numerical 1

key), see Chapter 3, “Using System Management Services.”

Ÿ The Open Firmware command line (started by pressing F8 or the numerical 8

key), see Chapter 3, “Using System Management Services.”

Ÿ Alternate boot modes (started by pressing F5 or the numerical 5 key, or F6 the

numerical 6 key), see “Working with System Startup Options.”

The last indicator to appear is the boot indicator. This indicator shows that the

server hardware is preparing to load and start the operating system.

At this point, the server prompts you for the power-on password if it has been set.

(See Chapter 3, “Using System Management Services,” for instructions on setting

passwords.)

If three incorrect responses are given to the password prompt, the server locks up

and must be turned off and turned on again to be reset. If the power-on password

has been lost, then the power-on password jumper must be reset or disabled:

Ÿ To reset the power-on password, remove the server power cable; then remove

the server battery for 30 seconds. See “Changing the Battery” on page 4-36 for

the location of the battery.

Ÿ To disable the power-on password, see “Enabling and Disabling the Power-On

Password” on page 4-8.

Attention: Removing the battery may also erase system configuration information

stored in the nonvolatile random access memory (NVRAM), such as the custom boot

list.

Note: If the privileged-access password has been lost, contact your authorized

reseller or marketing representative.

2-4 7046 Model B50 User's Guide

If no bootable operating system image is found on any of the storage devices listed

in the system firmware boot list, then the server attempts to boot again. With each

attempt, you have the opportunity to start the System Management Services (SMS)

as described in Chapter 3, “Using System Management Services.”

Stopping the Server

Attention: When you use the shutdown procedure for your server, enter the correct

shutdown command for your operating system before you stop the server. Failure to

do so may result in the loss of data. If you need information on the shutdown

procedure for your operating system, see the operating system documentation.

1. Before stopping the programs and operating system, notify your system

administrator and users that the server is going to be shut down.

2. After you shut down the operating system, turn off the server.

3. Set the power switches of the attached devices to Off.

Using the Power Switch and Indicator

The power switch and indicators on the front of your server allow you to control

power to the server, observe server power status, and observe disk activity.

These features also have other built-in capabilities to assist you in diagnosing system

problems and observing server status:

Ÿ When the server is turned on by pressing the power switch, the power LED lights

steadily.

Ÿ The disk drive LED lights whenever the hard disk drives within the server are

being used.

Ÿ If AIX is installed and running, a memory dump of system information can be

requested.

– To enable this function, the sysdumpdev -K command must be executed

before an error condition exists.

– To request the memory dump, press the reset button on the operator panel.

Requesting a memory dump directs AIX to save system information to a

predefined file before turning off the system. This feature can be used to

assist in recovery from system problems.

– When a memory dump has been requested, the power LED blinks quickly

(about 10 flashes per second) to indicate that the dump has been started.

This blinking ceases after about a minute whether or not the dump is

Chapter 2. Using the Server 2-5

complete, and the LED returns to its steady, lit state until the system turns off

or reboots when the dump is complete.

– The memory dump file can be viewed by entering the AIX command

sysdumpdev -L

Using the Operator Panel and Reset Switch

The operator panel on the front of the server contains a four-digit display and reset

button. The four-digit display is used by your server to display progress indicators

during system startup, and can also display error messages.

The function of the reset button depends on the operating system installed in the

server. Consult your operating system documentation for a description of its

function.

Working with System Startup Options

If no keys are pressed after the server power is turned on, the server searches a list

of devices (the default boot list) for a bootable image. If a bootable image is found,

then the server loads and starts the operating system. This is called a normal boot.

The server can also be booted from a custom boot list, which can be changed

through the System Management Services.

If certain keys are pressed during system startup, the server searches the default or

custom boot list for a bootable image to start in service mode instead of normal

mode. After a successful service mode boot, the diagnostic programs are started

automatically.

The following pages describe the default and custom boot lists, and how to boot from

these in either normal or service mode.

Default Boot List

The default boot list is composed of the first device found of each of the following

types:

1. Diskette drive

2. CD-ROM drive

3. Disk drive

4. Network device

2-6 7046 Model B50 User's Guide

If this default boot list is used during system startup, the server attempts to boot from

the diskette drive, then from the CD-ROM drive, then from the first disk drive

encountered, and finally the first network connection encountered.

Custom Boot List

The contents of the custom boot list can be defined by using the graphical System

Management Services or the text-based System Management Services. When the

custom boot list is used during system startup, the server attempts to boot in turn

from each specific device in the custom boot list.

Note: Only the specific devices contained in the custom boot list are checked for a

bootable image. Other devices of the same type are not searched for a

bootable image unless they are also specified in the custom boot list. Refer

to Chapter 3, “Using System Management Services” for more information on

custom boot lists.

If no bootable image is found in the custom boot list, then the server restarts and

attempts to boot again.

If the custom boot list is discovered to be corrupted, the server rebuilds the custom

boot list according to the default boot list.

Loading Diagnostics in Service Mode Boot

The server can be booted in service mode (instead of normal mode) from either the

default boot list or custom boot list. After a successful service mode boot, the

diagnostic programs are started automatically.

Booting in Service Mode from the Default Boot List

To boot in service mode from the default boot list, do the following:

1. Before stopping the programs and operating system, notify your system

administrator and users that the server is going to be shut down.

2. Insert the diagnostics CD-ROM into the CD-ROM drive, if you intend to run

standalone diagnostics.

3. Turn off the server.

4. Wait 30 seconds, then turn on the server.

5. When the keyboard indicator appears during startup, press the F5 key if the

system console is a directly attached keyboard, or the 5 key if the system

console is an ASCII terminal.

Chapter 2. Using the Server 2-7

6. Enter any passwords.

Diagnostics loaded from CD-ROM are called standalone diagnostics. Because the

default boot list checks the CD-ROM drive before the disk drive, this procedure is

used to start standalone diagnostics.

Booting in Service Mode from the Custom Boot List

To boot in service mode from the custom boot list, do the following:

1. Before stopping the programs and operating system, notify your system

administrator and users that the server is going to be shut down.

2. Turn off the server.

3. Wait 30 seconds, then turn on the server.

4. When the keyboard indicator appears during startup, press the F6 key if the

system console is a directly attached keyboard, or the 6 key if the system

console is an ASCII terminal.

5. Enter any passwords.

Diagnostics loaded from a disk drive or network are called online diagnostics. (Online

diagnostics can be used only if AIX is installed.) Because the custom boot list lists

the disk drive or network device before the CD-ROM drive, this procedure is used to

start online diagnostics. To ensure that using the custom boot list starts online

diagnostics, do not insert the diagnostics CD-ROM.

2-8 7046 Model B50 User's Guide

Working with Standalone versus Online Diagnostics

When the server attempts to boot in service mode (from either the default or custom

boot list) and locates a diagnostics CD-ROM before any other bootable image, then

the server starts standalone diagnostics.

Standalone diagnostics can be used on servers installed with any supported

operating system.

When the server attempts to boot in service mode (from either the default or custom

boot list) and first locates a bootable image on disk drive or network connection, then

the server starts online diagnostics.

Online diagnostics can be used only on servers installed with the AIX operating

system.

Because the type of diagnostics started (standalone or online) depends on the

source from which they are loaded, changing the boot list used during system startup

can affect which diagnostics are run.

Recommended Boot Options

The procedures under “Loading Diagnostics in Service Mode Boot” on page 2-7

produce the following recommended results:

Ÿ Default boot list (F5 or 5 key) with diagnostics CD-ROM inserted loads

Standalone Diagnostics.

Ÿ Custom boot list (F6 or 6 key) without diagnostics CD-ROM inserted loads Online

Diagnostics, if AIX is installed on a device in the custom boot list.

Using the Keyboards

There are several keyboards available with the server. The keyboards have various

keys that enter data and control the cursor location.

The functions of each keyboard depend on the software used. The character sets for

the keyboards are contained and explained in the documentation for your operating

system.

The keyboard is divided into four sections:

1 - Function keys are multipurpose keys and their function is controlled by the

operating system.

2 - Typewriter keys are similar to a standard typewriter. Their function is controlled by

the software.

3 - Control keys move the cursor on the screen and do programmed control

functions. The movement and functions depend upon the application used.

4 - The Numeric keypad is arranged like a calculator to help when typing numbers.

Chapter 2. Using the Server 2-11

On all of the keyboards, you can adjust the tilt position for typing comfort. To tilt the

keyboard, pull out on the keyboard legs. The legs snap into position. To decrease

the tilt of the keyboard, rotate the keyboard legs until they snap into the bottom of

the keyboard case.

The keyboard cable plugs into the connector at the rear of the server.

Using the Mouse

The mouse is a hand-operated locating device. Consult your application

documentation for the exact use of the three-button mouse.

You can use the mouse to perform functions such as positioning a cursor, selecting

items from a menu, or moving around in your document much easier and faster than

if you used only the keyboard. The cursor moves exactly as you move the mouse on

a flat surface, such as a desktop.

When you move the mouse around on a flat surface, the cursor moves on the

display screen; the movement changes the position of the cursor.

2-12 7046 Model B50 User's Guide

With the mouse buttons, you can perform functions such as selecting and

deselecting options, extending your selection, or choosing a command. The precise

function of your mouse depends on the software you are using.

The mouse has a cable that plugs into a connector at the rear of the server.

Handling the Mouse Correctly

For best operation, handle the mouse with care. Incorrect handling can damage the

mouse.

Do not:

Ÿ Operate the mouse on cloth, unfinished wood, newspaper, or carpet.

Ÿ Drop or hit the mouse.

Ÿ Carry the mouse by holding onto the cable.

Ÿ Expose the mouse to extreme temperatures or direct sunlight.

Ÿ Place the mouse in liquid spills.

Caring for the Mouse

The operating surface for the mouse should be smooth, clean, and flat. For

example, you can operate the mouse on the following surfaces:

Ÿ Finished wood

Ÿ Glass

Ÿ Enamel

Ÿ Plastic

Ÿ Paper (except newspaper)

Rough surfaces collect contaminants that can be transferred to the interior of the

mouse by the ball. Rough surfaces can also cause the pads located on the bottom

of the mouse to prematurely wear. A deeply pitted surface could cause erratic

operation of the mouse. The surface you use should be free from spills, dirt, dust,

lint, wax, eraser dust, and other foreign matter.

To care for the mouse:

Ÿ Inspect the work surface for spills or other contaminants.

Ÿ Dust the work surface.

Ÿ If you are using a paper pad, inspect it for wear and replace it if necessary.

Using the 3.5-Inch Diskette Drive

The following section provides information on 3.5-inch diskette drive.

Diskette Compatibility

The server has a 1.44MB diskette drive installed.

The 1.44MB diskette drive can format, read, and write diskettes compatible with the

following diskette drives:

Ÿ 1.0MB diskettes with 720KB formatted data capacity

Ÿ 2.0MB diskettes with 1.44MB formatted data capacity (HD).

Format the diskette according to its specified capacity.

Write-Protecting 3.5-Inch Diskettes

Write-protecting diskettes is necessary so that important information is not

accidentally lost. When diskettes are write-protected, you can read information from

the diskettes, but you cannot write information on them.

There is a write-protect tab on the 3.5-inch diskette.

To locate the write-protect tab, turn the diskette over with the label facing down.

Ÿ To prevent writing onto a diskette, slide the write-protect tab to open the protect

slot.

Chapter 2. Using the Server 2-15

Ÿ To allow writing onto a diskette, slide the write-protect tab to cover the protect

slot.

Loading and Unloading the 3.5-Inch Diskette

To load a diskette into the drive, insert the diskette in the diskette drive with the

Loading the CD-ROM Drive

Press the unload button to open the tray. Place the disc in the tray with the printed

side up. Push gently on the load/unload button. The drive automatically pulls the

tray into the drive and prepares the disc for reading.

Unloading the CD-ROM Drive

Push and hold the unload button until the drawer comes out and then remove the

disc.

Cleaning the CD-ROM Drive

This CD-ROM drive has an internal head-cleaning mechanism, and therefore does

not require an external cleaning device. The internal cleaning mechanism cleans the

head every time the tray is closed with a disc in the tray.

Always handle discs carefully by the edges to avoid leaving fingerprints or scratching

them (this helps the disc to maintain good readability). Wipe discs with a soft,

lint-free cloth or lens tissue. Always wipe in a straight line from the inner hub to the

outer rim.

Password

When you select this icon, the following screen is displayed.

Power-On Password

Setting a power-on password helps protect information stored in your server. If a

power-on password is set for your server, the Power-On status icon is shown in the

locked position. If a power-on password is not set, then the Power-On status icon is

shown in the unlocked position (as shown in the screen above).

When you select the Entry icon, a screen with eight empty boxes displays. Type

your password in these boxes. You can use any combination of up to eight

characters (A–Z, a–z, and 0–9) for your password. As you type a character, a key

appears in the box.

Chapter 3. Using System Management Services 3-11

Press Enter when you are finished; you must type the password again for

verification.

If you type the password incorrectly, press Esc and start again.

After you have entered and verified the password, the power-on password status

icon flashes and changes to the locked position to indicate that the power-on

password is installed.

If you previously had set a power-on password and want to remove it, select the

Remove icon.

Notes:

1. If you want to disable an installed power-on password (but not erase it), move

the power-on password jumper as described in the section beginning on page

4-8. Moving the jumper back to the default position re-enables the power-on

password, unless it has been removed in the System Management Services

Utilities or by removing the battery.

2. If you forget the power-on password, you can erase the password by shutting

down the server and removing the battery for at least 30 seconds. See

“Changing the Battery” on page 4-36 for details.

3. The server power cable must be disconnected before removing the battery.

A password becomes effective only after the server is turned off and back on again.

3-12 7046 Model B50 User's Guide

Remote Mode: The remote mode, when enabled, allows the system to start from

the defined boot device. This mode is ideal for network servers and other servers

that operate unattended. You must set a power-on password before you can enable

the remote mode. When the remote mode is set, the icon label changes to Remote

<On>.

If you remove the power-on password, the remote mode is automatically reset, and

the icon label returns to Remote <Off>.

Note: To use the remote mode feature for booting unattended devices, you must

enable the automatic power-up feature. See “Enabling Automatic Power-Up”

on page 4-13 for instructions on enabling the automatic power-up feature,

which allows the server to turn on whenever AC power is applied to the

server (instead of having the server wait for the power button to be pushed).

Privileged-Access Password

The privileged-access password protects against the unauthorized starting of the

system programs. To set the privileged-access password, you must first change a

jumper on the system board. See Chapter 4, “Installing and Removing Options” on

page 4-1 to locate and change the password-enabling jumper, then return here.

If the password-enabling jumper has been changed, select the Entry icon to set and

verify the privileged-access password.

When you select the Entry icon, a screen with eight empty boxes displays. Type

your password in these boxes. You can use any combination of up to eight

characters (A–Z, a–z, and 0–9) for your password. As you type a character, a key

appears in the box.

Chapter 3. Using System Management Services 3-13

Press Enter when you are finished; you must type the password again for

verification.

If you type the password incorrectly, press the Esc key and start again.

Note: If an error occurs when you attempt to set the privileged-access password,

then make sure the password-enabling jumper has been changed. (See

Chapter 4, “Installing and Removing Options” on page 4-1 for instructions on

changing the password-enabling jumper.)

After you have entered and verified the password, the privileged-access password

icon flashes and changes to the locked position to indicate that your server now

requires the password you just entered before running system programs.

Attention:

1. Once the password-enabling jumper has been changed and the

privileged-access password has been set, great care must be taken to preserve

the privileged-access password. If you set the privileged-access password and

later misplace it, your server must be returned for service.

To prevent loss of system use, record the privileged-access password

immediately whenever it is changed.

2. If no user-defined boot-list exists, and the privileged-access password has been

enabled, you are asked for the privileged-access password at startup every time

you boot your server.

Moving the password-enabling jumper back to the default position does not disable

or erase the privileged-access password. Removing the jumper or moving the

jumper back to the default position only prohibits changing or disabling this password

with the System Management Services.

Safety Considerations

Observe the following safety precautions anytime you work with the server.

DANGER

An electrical outlet that is not correctly wired could place hazardous

voltage on metal parts of the system or the devices 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 power

cables for the system unit and all attached devices are unplugged.

When adding or removing any additional 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 three–wire power cable and plug for the user's

safety. Use this power cable with a properly grounded electrical outlet to avoid

electrical shock.

DANGER

To prevent electrical shock hazard, disconnect the power cable from

the electrical outlet before relocating the server.

4-2 7046 Model B50 User's Guide

Handling Static Sensitive Devices

Attention: Static electricity can damage this device and your system unit. To avoid

damage, keep this device in its static protective bag until you are ready to install it.

To reduce the possibility of electrostatic discharge, follow the precautions listed

below.

Electrostatic Discharge Protection

To prevent electrostatic discharge:

Ÿ Limit your movement. Movement can cause static electricity to build up around

you.

Ÿ Handle the device carefully, holding it by its edges or its frame.

Ÿ Do not touch solder joints, pins, or exposed printed circuitry.

Ÿ Do not leave the device where others can handle and possibly damage the

device.

Ÿ While the device is still in its anti-static package, touch it to an unpainted metal

part of the system unit for at least two seconds. (This drains static electricity

from the package and from your body.)

Ÿ Remove the device from its package and install it directly into your system unit

without setting it down. If it is necessary to set the device down, place it on its

static-protective package. (If your device is an adapter, place it component side

up.) Do not place the device on your system unit cover or on a metal table.

Ÿ Take additional care when handling devices during cold weather as heating

reduces indoor humidity and increases static electricity.

Tools Required

To install or remove options from your server, you need a flat-blade screwdriver.

Any additional tools needed depend upon the specific option and are noted in the

instructions that come with the option.

Chapter 4. Installing and Removing Options 4-3

3. Turn off all attached devices and the server.

4. If you have a modem or fax machine attached to the server, disconnect the

telephone line from the server.

5. Unplug all power cords (cables) from electrical outlets.

Attention: As soon as the server power cord is plugged in to the server and

power outlet, the power is on within the server whether or not the server is

turned on. Do not plug in the server power cord if the cover of the server is

removed.

4-4 7046 Model B50 User's Guide

Chapter 5. Using the Online and Standalone Diagnostics

The diagnostics consist of Standalone Diagnostics and Online Diagnostics.

Standalone Diagnostics are packaged on removable media and must be booted

before they can be run. If booted, they have no access to the AIX Error Log or the

AIX Configuration Data.

Online Diagnostics, when installed, reside with AIX in the file system. They can be

booted:

Ÿ in single user mode (referred to as service mode),

Ÿ run in maintenance mode (referred to as maintenance mode)

Ÿ run concurrently (referred to as concurrent mode) with other applications.

If the system is not booted, then the Online Diagnostics have access to the AIX Error

Log and the AIX Configuration Data.

Standalone and Online Diagnostics Operating Considerations

Note: When possible, run Online Diagnostics in Service Mode. Online Diagnostics

perform additional functions, compared to Standalone Diagnostics. This ensures that

the error state of the system is captured in NVRAM for your use in fixing the

problem. The AIX error log and certain SMIT functions are only available when

diagnostics are run from the disk drive.

Consider the following items before using the diagnostics:

Ÿ When diagnostics are installed, the device support for some devices may not get

installed. If this is the case, that device does not appear in the diagnostic test

list when running disk-based diagnostics.

Ÿ Support for some TTY terminals is optionally installed. If you attach a TTY

terminal to a system to run diagnostics, it may not work properly because the

AIX support for the terminal may not be installed.

Selecting a Console Display

When you run Standalone Diagnostics (and under some conditions Online

Diagnostics), you must select the console display. The diagnostics can display

instructions on any graphics display and the terminal attached to the S1 serial port.

 Copyright IBM Corp. 1999

5-1

Identifying the Terminal Type to the Diagnostics

Note: This is not the same as selecting a console display.

When you run diagnostics, you must identify what type of terminal you are using. If

the terminal type is not known when the FUNCTION SELECTION menu is displayed,

the diagnostics do not allow you to continue until a terminal is selected from the

DEFINE TERMINAL option menu. Select lft for graphical displays.

Undefined Terminal Types

If you specify an undefined terminal type from the DEFINE TERMINAL option menu,

the menu prompts the user to enter a valid terminal type. The menu is redisplays

until either a valid type is entered or you exit the DEFINE TERMINAL option.

Resetting the Terminal: If you enter a terminal type that is valid (according to

the DEFINE TERMINAL option menu) but is not the correct type for the ASCII

terminal being used, you may be unable to read the screen, use the function keys, or

use the Enter key. These difficulties can be bypassed by pressing Ctrl-C to reset the

terminal. The screen display which results from this reset depends on the mode in

which the system is being run:

Ÿ Online Normal or Maintenance Mode - The command prompt appears.

Ÿ Standalone Mode or Online Service Mode -The terminal type is reset to dumb, the

Diagnostic Operating Instruction panel displays, and you are required to go

through the DEFINE TERMINAL process again.

Running Standalone Diagnostics

Consider the following when you run Standalone Diagnostics:

Ÿ The diagnostic CD must remain in the CD-ROM drive for the entire time that

diagnostics are running.

Ÿ The diagnostic CD-ROM cannot be ejected from the CD-ROM drive once the

diagnostics have loaded. The CD can only be ejected after the system has been

turned off and then turned on (standalone mode) or after the diagnostics program

has terminated (online concurrent mode).

Ÿ The CD-ROM drive from which diagnostics were loaded cannot be tested.

Ÿ The SCSI adapter (or circuitry) controlling the CD-ROM drive from which

diagnostics were loaded cannot be tested.

5-2 7046 Model B50 User's Guide

Running Online Diagnostics

Consider the following when you run the Online Diagnostics from a server or a disk:

Ÿ The diagnostics cannot be loaded and run from a disk until the AIX operating

system has been installed and configured. After the AIX operating system has

been installed, all three modes of diagnostics are available.

Ÿ The diagnostics cannot be loaded on a system (client) from a server if that

system is not set up to boot from a server over a network. When the system is

set up to boot from a server, the diagnostics are run in the same manner as they

are from disk.

Ÿ If the diagnostics are loaded from disk or a server, you must shut down the AIX

operating system before turning the system unit off to prevent possible damage

to disk data. This is done in one of two ways:

– If the diagnostics were loaded in standalone mode, press the F3 key until

DIAGNOSTIC OPERATING INSTRUCTIONS displays. Then press the F3

key once again to shut down the AIX operating system.

– If the diagnostics were loaded in maintenance or concurrent mode, enter the

shutdown -F command.

Ÿ Under some conditions the system may stop, with instructions displayed on

attached displays and terminals. Follow the instructions to select a console

display.

Running the Diagnostics from a TTY Terminal

Consider the following when you run diagnostics using a TTY-type terminal as the

console display:

Ÿ See the operator manual for your type of TTY terminal to find the key sequences

you need to respond to the diagnostics. For the 3151, refer to the 3151 ASCII

Display Station Guide to Operations, form number GA18-2633. For the 3164,

refer to the 3164 ASCII Color Display Station Description, form number

GA18-2617.

Ÿ When the diagnostics present information through the Serial 1 port to the ASCII

display, certain attributes are used. These attributes are set as if the diagnostics

were using a 3161 display terminal. The following tables list attributes for the

3161 ASCII Display Terminal and for two other ASCII display terminals

commonly used with the system.

Ÿ If you have a TTY terminal other than a 3151, 3161, or 3164 attached to the S1

serial port, your terminal may have different names for the attributes. Use the

attribute descriptions in the following tables to determine the settings for your

terminal.

Chapter 5. Using the Online and Standalone Diagnostics 5-3

General Attributes Always Required

Online Diagnostics Modes of Operation

The Online Diagnostics can be run in three modes:

Ÿ Service Mode

Ÿ Concurrent Mode

Ÿ Maintenance Mode

Service Mode

Service mode provides the most complete checkout of the system resources. This

mode also requires that no other programs be running on the system. All system

resources, except the SCSI adapter and the disk drives used for paging, can be

tested. However, note that the memory and processor are only tested during POST,

and the results of the POST tests are reported by diagnostics.

Error-log analysis is done in service mode when you select the Problem

Determination option on the DIAGNOSTIC MODE SELECTION menu.

Running the Online Diagnostics in Service Mode

To run Online Diagnostics in service mode, use the following steps:

1. Ask the system operator to stop all programs, including the AIX operating system

2. Turn the power off.

3. Remove all tapes, diskettes, and CD-ROMs.

4. Turn the power on.

a. When or after the Keyboard indicator appears, press 6 on the keyboard to

indicate that diagnostics are to be loaded.

b. Enter any requested passwords.

c. Follow any instructions to select a console.

5. After the diagnostic controller loads, DIAGNOSTIC OPERATING

INSTRUCTIONS appear on the console display.

6. Follow the displayed instructions to check out the desired resources.

7. When testing is complete, use the 3 key to return to the DIAGNOSTIC

OPERATING INSTRUCTIONS.

8. Press the 3 key (from a defined terminal) or press 99 (for an undefined terminal)

to shut down the diagnostics before turning off the system unit.

5-10 7046 Model B50 User's Guide

Note: Pressing the 3 key (from a defined terminal) produces a Confirm Exit popup

menu which offers two options: continuing with the shut down by pressing

the 3 key; or returning to diagnostics by pressing Enter.

For undefined terminals, pressing 99 produces a full-screen menu which

offers two options: continuing with the shutdown by pressing 99 and then

Enter; or returning to diagnostics by pressing Enter.

Concurrent Mode

Concurrent mode provides a way to run Online Diagnostics on some of the system

resources while the system is running normal activity.

Because the system is running in normal operation, some of the resources cannot be

tested in concurrent mode. The following resources cannot be tested in concurrent

mode:

Ÿ SCSI adapters connected to paging devices

Ÿ Disk drive used for paging

Ÿ Some display adapters and graphics related devices

Ÿ Memory (tested during POST)

Ÿ Processor (tested during POST).

There are three levels of testing in concurrent mode:

Ÿ The share-test level tests a resource while the resource is being shared by

programs running in the normal operation. This testing is mostly limited to normal

commands that test for the presence of a device or adapter.

Ÿ The sub-test level tests a portion of a resource while the remaining part of the

resource is being used in normal operation. For example, this test could test one

port of a multiport device while the other ports are being used in normal

operation.

Ÿ The full-test level requires the device not be assigned to or used by any other

operation. This level of testing on a disk drive may require the use of the varyoff

command. The diagnostics display menus to allow you to vary off the needed

resource.

Error-log analysis is done in concurrent mode when you select the Problem

Determination option on the DIAGNOSTIC MODE SELECTION menu.

To run the Online Diagnostics in concurrent mode, you must be logged on to the AIX

operating system and have proper authority to issue the commands (if needed get

help from the system operator).

Chapter 5. Using the Online and Standalone Diagnostics 5-11

The diag command loads the diagnostic controller and displays the Online

Diagnostic menus.

Running the Online Diagnostics in Concurrent Mode

To run Online Diagnostics in concurrent mode, use the following steps:

1. Log on to the AIX operating system as root or superuser (su).

2. Enter the diag command.

3. When the DIAGNOSTIC OPERATING INSTRUCTIONS display, follow the

instructions to check out the desired resources.

4. When testing is complete; use the 3 key to return to the DIAGNOSTIC

OPERATING INSTRUCTIONS. Then press the 3 key again to return to the AIX

operating system prompt. Be sure to vary on any resource you had varied to off.

5. Press the Ctrl-D key sequence to log off from root or superuser (su).

Maintenance Mode

Maintenance mode runs the Online Diagnostics using the customer's version of the

AIX operating system. This mode requires that all activity on the AIX operating

system be stopped so the Online Diagnostics have most of the resources available

to check. All of the system resources except the SCSI adapters, memory, processor,

and the disk drive used for paging can be checked.

Error log analysis is done in maintenance mode when you select the Problem

Determination option on the DIAGNOSTIC MODE SELECTION menu.

The shutdown -m command is used to stop all activity on the AIX operating system

and put the AIX operating system into maintenance mode. Then the diag command

is used to invoke the diagnostic controller so you can run the diagnostics. After the

diagnostic controller is loaded, follow the normal diagnostic instructions.

Running the Online Diagnostics in Maintenance Mode

To run the Online Diagnostics in maintenance mode, you must be logged on to the

customer's version of the AIX operating system as root or superuser (su) and use the

shutdown -m and diag commands. Use the following steps to run the Online

Diagnostics in maintenance mode:

1. Stop all programs except the AIX operating system (get help from the system

operator if needed).

2. Log onto the AIX operating system as root or superuser (su).

5-12 7046 Model B50 User's Guide

3. Enter the shutdown -m command.

4. When a message indicates the system is in maintenance mode, enter the diag

command.

Note: It may be necessary to set TERM type again.

Chapter 6. Location Codes

The 7046 Model B50 uses physical location codes in conjunction with AIX location

codes to provide mapping of the failing field replaceable units. The location codes

are produced by the system unit's firmware and AIX.

Physical Location Codes

Physical location codes provide a mapping of logical functions in a platform (or

expansion sites for logical functions, such as connectors or ports) to their specific

locations within the physical structure of the platform.

Location Code Format

The format for the location code is a string of alphanumeric characters separated by

a dash (-), slash (/), pound sign (#), or period (.).

Ÿ The base location is all of the information before the slash (/) or pound sign (#).

It identifies a device that is connected or plugged into the parent.

Ÿ Extended location information follows the slash (/). It identifies a device that is

part of the parent, a connector, or a cable.

Ÿ Cable information follows the pound sign (#). It identifies a cable that is

connected to the parent.

The following are examples:

P1-C1

P1-M1

P1-K1

P1/S1

Identifies a CPU card C1 plugged into planar P1.

Identifies a memory card M1 plugged into planar P1.

Identifies a keyboard attached to connector K1 on planar P1.

Identifies serial port 1 controller on planar P1, the connector for serial port

1, or the cable attached to connector S1.

P1-I2/E3 Identifies Ethernet controller 3 on the card plugged into slot 2 (I2) on

planar P1, the connector for Ethernet controller 3, or the cable attached to

Ethernet controller 3.

P1-I2#E3 Identifies the cable attached to Ethernet controller 3 plugged into slot 2

(I2) on planar P1.

Sub-locations, such as memory modules on a base memory card or a specific SCSI

address, are identified by a period (.). The following are examples:

P1-M1.4 Identifies DIMM 4 on memory card 1 on planar 1.

 Copyright IBM Corp. 1999

6-1

1-C1.1

Identifies CPU 1 on CPU card 1 on planar 1.

P2/Z1-A3.1 Identifies a SCSI device with a SCSI address of LUN 1 at SCSI ID 3

attached to SCSI bus 1 from planar 2.

P1-I2#E3.2 Identifies the second cable in a series of cables attached to Ethernet

controller 3 in slot 2 (I2) on planar 1.

Depending on the AIX and firmware levels, AIX Diagnostics may include extended

location information when identifing a planar or card. The extended location

information is always included when identifing a cable or connector. Location codes

with extended location information that display without a description identifing the

devices, always identify the cable attached to the port.

AIX Location Codes

The basic formats of the AIX location codes are:

Ÿ For non-SCSI devices/drives:

AB-CD-EF-GH

Ÿ For SCSI devices/drives:

AB-CD-EF-G,H

non-SCSI devices/drives

The location code for for planars, cards, and non-SCSI devices is defined as:

Chapter 6. Location Codes 6-3

AB-CD-EF-GH

| | | |

| | | Device/FRU/Port ID

| | Connector ID

| devfunc Number, Adapter Number or Physical Location

Bus Type or PCI Parent Bus

Ÿ The AB value identifies a bus type or PCI parent bus as assigned by the

firmware.

Ÿ The CD value identifies adapter number, adapter's devfunc number, or physical

location. The devfunc number is defined as the PCI device number times 8, plus

the function number.

Ÿ The EF value identifies a connector.

Ÿ The GH value identifies a port, address, device, or FRU.

Adapters and cards are identified with AB-CD.

The possible values for AB are:

Processor bus

ISA bus

EISA bus

MCA bus

PCI bus used in the case where the PCI bus cannot be identified

PCMCIA buses

For PCI adapters where x is equal to or greater than 1. The x and y are

characters in the range of 0-9, A-H, J-N, P-Z (O, I, and lowercase are

omitted) and are equal to the parent bus's ibm, aix-loc Open Firmware

Property.

The possible values for CD depend on the adapter/card:

Ÿ For pluggable PCI adapters/cards, CD is the device's devfunc number (PCI

device number times 8, plus the function number). The C and D are characters

in the range of 0-9, and A-F (hex numbers). Location codes therefore uniquely

identify multiple adapters on individual PCI cards.

Ÿ For pluggable ISA adapters, CD is equal to the order the ISA cards

defined/configured either by SMIT or the ISA Adapter Configuration Service Aid.

6-4 7046 Model B50 User's Guide

Ÿ For integrated ISA adapters, CD is equal to a unique code identifying the ISA

adapter. In most cases, this code is equal to the adapter's physical location code.

In cases where a physical location code is not available, CD is FF.

EF is the connector ID, used to identify the adapter's connector to which a resource

is attached.

GH is used to identify a port, device, or FRU. For example:

Ÿ For async devices, GH defines the port on the fanout box. The values are 00 to

15.

Ÿ For a diskette drive, H identifies either diskette drive 1 or 2. G is always 0.

Ÿ For all other devices, GH is equal to 00.

For integrated adapter, EF-GH is the same as the definition for a pluggable adapter.

For example, the location code for a diskette drive is 01-D1-00-00. A second

diskette drive is 01-D1-00-01.

SCSI devices/drives

The location code for SCSI devices and drives is defined as:

AB-CD-EF-G,H

| | | | |

| | | | Logical Unit address of the SCSI Device

| | | Control Unit Address of the SCSI Device

| | Connector ID

| devfunc Number, Adapter Number or Physical Location

Bus Type or PCI Parent Bus

Where:

Ÿ AB-CD-EF are the same as non-SCSI devices.

Ÿ G defines the control unit address of the device. Values of 0 to 15 are valid.

Ÿ H defines the logical unit address of the device. Values of 0 to 255 are valid.

A bus location code is also generated as 00-XXXXXXXX, where XXXXXXXX is

equivalent to the node's unit address.

Chapter 9. Introducing Tasks and Service Aids

The AIX Diagnostic Package contains programs that are called Tasks. Tasks can be

thought of as "performing a specific function on a resource"; for example, running

diagnostics, or performing a service aid on a resource. This chapter describes the

Tasks available in AIX Diagnostics Version 4.2 and later.

Note: Many of these programs work on all system model architectures. Some

programs are only accessible from Online Diagnostics in Service or

Concurrent mode, others may be accessible only from Standalone

Diagnostics. While still other programs may only be supported on a particular

system architecture, such as CHRP (Common Hardware Reference Platform).

To perform one of these tasks, use the Task Selection option from the FUNCTION

SELECTION menu.

Once a task is selected, a resource menu may be presented showing all resources

supported by the task.

A fast path method is also available to perform a task by using the diag command

and the -T flag. This means the user does not have to go through most of the

introductory menus just to get to a particular task. Instead, the user is presented

with a list of resources available to support the specified task. The current fast path

tasks are:

Ÿ Certify – certifies media

Ÿ Chkspares – checks for the availability of spare sectors

Ÿ Download – downloads microcode to an adapter or device

Ÿ Disp_mcode – displays current level of microcode

Ÿ Format – formats media

Ÿ Identify – identifies the PCI RAID physical disks

To run these tasks directly from the command line, specify the resource and other

task unique flags. Use the descriptions in this chapter to understand which flags are

needed for a given task.

Chapter 9. Introducing Tasks and Service Aids 9-3

Add Resource to Resource List

Use this task to add resources back to the resource list.

Note: Only resources that were previously detected by the diagnostics and deleted

from the Diagnostic Test List are listed. If no resources are available to be added,

then none are listed.

AIX Shell Prompt

Note: Use in Online Service Mode only.

This service aid allows access to the AIX command line. To use this service aid the

user must know the root password (when a root password has been established).

Note: Do not use this task to install code, or change the configuration of the

system. This task is intended to view files, configuration records, and data.

Changing the system configuration or installing code with this service aid may

produce unexplained system problems after exiting the diagnostics.

Analyze Adapter Internal Log

The PCI RAID adapter has an internal log that logs information about the adapter

and the disk drives attached to the adapter. Whenever data is logged in the internal

log, the device driver copies the entries to the AIX system error log and clears the

internal log.

The Analyze Adapter Internal Log service aid analyzes these entries in the AIX

system error log. The service aid displays the errors and the associated service

actions. Entries that do not require any service actions are ignored.

Backup and Restore Media

This service aid allows verification of backup media and devices. It presents a menu

of tape and diskette devices available for testing and prompts for selection of the

desired device. It then presents a menu of available backup formats and prompts for

selection of the desired format. The supported formats are tar, backup, and cpio.

After the device and format are selected, the service aid backups a known file to the

selected device, restores that file to /tmp, and compares the original file to the

restored file. The restored file is also left in /tmp to allow for visual comparison. All

errors are reported.

9-4 7046 Model B50 User's Guide

Certify Media

This task allows the selection of diskette or hardfiles to be certified.

Hardfiles can be connected either to a SCSI adapter (non-RAID) or a PCI SCSI

RAID adapter. The usage and criteria for a hardfile connected to a non-RAID SCSI

adapter are different from those for a hardfile connected to a PCI SCSI RAID

adapter.

Ÿ Certify Diskette

This selection provides a way to verify the data written on a diskette. When this

service aid is selected, a menu asks you to select the type of diskette being

verified. The program then reads all of the ID and data fields on the diskette one

time and displays the total number of bad sectors found.

Ÿ Certify Hardfile Attached to a Non-RAID SCSI Adapter

This selection reads all of the ID and data fields. It checks for bad data and

counts all errors encountered. If the unrecovered data errors exceed the

threshold value, the hardfile needs to be formatted and certified. If the recovered

data errors, recovered and unrecovered equipment errors exceed the threshold

values, the disk needs to be replaced.

This task may be run directly from the AIX command line. The following usage

statement describes the syntax of the command:

Usage:

diag -c -d <deviceName> -T "certify"

Ÿ Certify Hardfile attached to a PCI SCSI RAID Adapter

This selection is used to certify physical disks attached to a PCI SCSI RAID

adapter. Certify reads the entire disk and checks for recovered errors,

unrecovered errors and reassigned errors. If these errors exceed the threshold

values, the user is prompted to replace the physical disk.

This task may be run directly from the AIX command line. The following usage

statement describes the syntax of the command:

Usage:

diag -c -d < RAID adapterName > -T "certify {-l < chID > | -A}"

Flag

-I

-A

Description

Physical Disk channel/ID (example: 27)

All disks.

Chapter 9. Introducing Tasks and Service Aids 9-5

Change Hardware Vital Product Data

Use this service aid to display the Display/Alter VPD Selection Menu. The menu lists

all resources installed on the system. When a resource is selected a menu is

displayed that lists all the VPD for that resource.

Note: The user cannot alter the VPD for a specific resource unless it is not machine

readable.

Configure Dials and LPFKeys

This service aid provides a tool for configuring and removing dials/LPFKs to the

asynchronous serial ports.

Since version 4.1.3 a tty must be defined on the async port before the Dials and

LPFKs can be configured on the port. Before version 4.2 the Dials and LPFKs could

only be configured on the standard serial ports. At version 4.2 the Dials and LPFKs

can be configured on any async port.

This selection invokes the SMIT utility to allow Dials and LPFKs configuration. A tty

must be in the available state on the async port before the Dials and LPFKs can be

configured on the port. The task allows an async adapter to be configured, then a

tty port defined on the adapter, and then Dials and LPFKs can be defined on the

port.

Configure Reboot Policy

This service aid controls how the system tries to recover from a system crash.

Use this service aid to display and change the following settings for the Reboot

Policy.

Note: Because of system capability, some of the following settings may not be

displayed by this service aid.

Ÿ Maximum Number of Reboot Attempts

Enter a number that is 0 or greater.

Note: A value of 0 indicates 'do not attempt to reboot' to a crashed system.

This number is the maximum number of consecutive attempts to reboot the

system. The term "reboot", in the context of this service aid, is used to describe

bringing system hardware back up from scratch, for example from a system reset

or power on.

9-6 7046 Model B50 User's Guide

When the reboot process completes successfully, the reboot attempts count is

reset to 0, and a "restart" begins. The term "restart", in the context of this service

aid, is used to describe the operating system activation process. Restart always

follows a successful reboot.

When a restart fails, and a restart policy is enabled, the system attempts to

reboot for the maximum number of attempts.

Ÿ Use the O/S Defined Restart Policy (1=Yes, 0=No)

When 'Use the O/S Defined Restart Policy' is set to Yes, the system attempts to

reboot from a crash if the operating system has an enabled Defined Restart or

Reboot Policy.

When 'Use the O/S Defined Restart Policy' is set to No, or the operating system

restart policy is undefined, then the restart policy is determined by the

'Supplemental Restart Policy'.

Ÿ Enable Supplemental Restart Policy (1=Yes, 0=No)

The 'Supplemental Restart Policy', if enabled, is used when the O/S Defined

Restart Policy is undefined, or is set to False.

When surveillance detects operating system inactivity during restart, an enabled

'Supplemental Restart Policy' causes a system reset and the reboot process

begins.

Chapter 9. Introducing Tasks and Service Aids 9-7

Ÿ Call-Out Before Restart (on/off)

When enabled, Call-Out Before Restart allows the system to call out (on a serial

port that is enabled for call-out) when an operating system restart is initiated.

Such calls can be valuable if the number of these events becomes excessive,

thus signalling bigger problems.

Ÿ Enable Unattended Start Mode (1=Yes, 0=No)

When enabled, 'Unattended Start Mode' allows the system to recover from the

loss of AC power.

If the system was powered On when the AC loss occurred, the system reboots

when power is restored. If the system was powered Off when the AC loss

occurred, the system remains off when power is restored.

This service aid may be accessed directly from the AIX command line, by entering:

/usr/lpp/diagnostics/bin/uspchrp -b

Configure Remote Maintenance Policy

The Remote Maintenance Policy includes modem configurations and phone numbers

to use for remote maintenance support.

This is the number for a pager carried by someone who responds to problem

calls from your system.

Ÿ Customer Voice Phone Number

This is the number for a telephone near the system, or answered by someone

responsible for the system. This is the telephone number left on the pager for

callback.

Ÿ Customer System Phone Number

This is the number to which your system's modem is connected. The service or

administration center representatives need this number to make direct contact

with your system for problem investigation. This is also referred to as the Call-In

phone number.

Ÿ Customer Account Number

This number could be used by a service provider for record keeping and billing.

Ÿ Call-Out Policy Numbers to call if failure

Chapter 9. Introducing Tasks and Service Aids 9-9

This is set to either 'first' or 'all'. If the call-out policy is set to 'first', call-out stops

at the first successful call to one of the following numbers in the order listed:

1. Service Center

2. Customer Admin Center

3. Pager

If Call-Out Policy is set to 'all', call-out attempts to call all of the following

numbers in the order listed:

Create Customized Configuration Diskette

This selection invokes the Diagnostic Package Utility Service Aid which allows the

user to perform the following action:

Ÿ Create a Standalone Diagnostic Package Configuration Diskette

Chapter 9. Introducing Tasks and Service Aids 9-11

The Standalone Diagnostic Package Configuration Diskette allows the following

to be changed from the console:

– Default refresh rate for a LFT

The refresh rate used by the standalone diagnostic package is 60Hz. If the

display's refresh rate is 77Hz, then set the refresh rate to 77.

– Different async terminal console

A console configuration file that allows a terminal attached to any RS232 or

RS422 adapter to be selected as a console device can be created using this

service aid. The default device is a RS232 tty attached to the first standard

serial port (S1).

Delete Resource from Resource List

Use this task to delete resources from the resource list.

Note: Only resources that were previously detected by the diagnostics and have not

been deleted from the Diagnostic Test List are listed. If no resources are available

to be deleted, then none are listed.

Disk Maintenance

Ÿ Disk to Disk Copy

Ÿ Display/Alter Sector

Disk to Disk Copy

Notes:

1. This service aid cannot be used to update to a different size drive. The service

aid only supports copying from a SCSI drive to another SCSI drive of similar

size.

2. Use the migratepv command when copying the contents to other disk drive

types. This command also works when copying SCSI disk drives or when

copying to a different size SCSI disk drive. Refer to System Management Guide:

Operating System and Devices for a procedure on migrating the contents of a

physical volume.

This selection allows you to recover data from an old drive when replacing it with a

new drive. The service aid recovers all LVM software reassigned blocks. To prevent

corrupted data from being copied to the new drive, the service aid aborts if an

unrecoverable read error is detected. To help prevent possible problems with the

9-12 7046 Model B50 User's Guide

new drive, the service aid aborts if the number of bad blocks being reassigned

reaches a threshold.

The procedure for using this service aid requires that both the old and new disks be

installed in or attached to the system with unique SCSI addresses. This requires

that the new disk drive SCSI address must be set to an address that is not currently

in use and the drive be installed in an empty location. If there are no empty

locations, then one of the other drives must be removed. Once the copy is

complete, only one drive may remain installed. Either remove the target drive to

return to the original configuration, or perform the following procedure to complete

the replacement of the old drive with the new drive.

1. Remove both drives.

2. Set the SCSI address of the new drive to the SCSI address of the old drive.

3. Install the new drive in the old drive's location.

4. Install any other drives that were removed into their original location.

To prevent problems that may occur when running this service aid from disk, it is

suggested that this service aid be run from the diagnostics that are loaded from

removable media when possible.

Display/Alter Sector

This selection allows the user to display and alter information on a disk sector. Care

must be used when using this service aid because inappropriate modification to

some disk sectors may result in total loss of all data on the disk. Sectors are

addressed by their decimal sector number. Data is displayed both in hex and in

ASCII. To prevent corrupted data from being incorrectly corrected, the service aid

does not display information that cannot be read correctly.

Display Configuration and Resource List

This service aid displays the item header only for all installed resources. Use this

service aid when there is no need of seeing the VPD. (No VPD is displayed.)

Display Firmware Device Node Information

This task displays the firmware device node information that appears on CHRP

platforms. The format of the output data may not be the same between different

levels of the AIX operating system. It is intended to gather more information about

individual or particular devices on the system.

Chapter 9. Introducing Tasks and Service Aids 9-13

Display Hardware Error Report

This service aid provides a tool for viewing the hardware error log. It uses the errpt

command.

The Display Error Summary and Display Error Detail selection provide the same type

of report as the errpt command. The Display Error Analysis Summary and Display

Error Analysis Detail selection provide additional analysis.

Display Hardware Vital Product Data

This service aid displays all installed resources along with any VPD for those

resources. Use this service aid when you want to look at the VPD for a specific

resource.

Display Machine Check Error Log

Note: The Machine Check Error Log Service Aid is available only on Standalone

Diagnostics.

When a machine check occurs, information is collected and logged in a NVRAM

error log before the server shuts down. This information is logged in the AIX error

log and cleared from NVRAM when the system is rebooted from the hard disk, LAN,

or standalone media. When booting from Standalone Diagnostics, this service aid

can take the logged information and turn it into a readable format that can be used to

isolate the problem. When booting from the hard disk or LAN, the information can

be viewed from the AIX error log using the Hardware Error Report Service Aid. In

either case the information is analyzed when running the sysplanar0 diagnostics in

Problem Determination Mode.

Display Microcode Level

The following usage statements describe the syntax of the command to display the

current level of microcode on an adapter or device.

Usage:

diag -c -d <device_name> -T "disp_mcode"

9-14 7046 Model B50 User's Guide

Display or Change Bootlist

This service aid allows the bootlist to be displayed, altered, or erased.

The system attempts to perform an IPL from the first device in the list. If the device

is not a valid IPL device or if the IPL fails, the system proceeds in turn to the other

devices in the list to attempt an IPL.

Display or Change Diagnostic Run Time Options

The Display or Change Diagnostic Run Time Options task allows the diagnostic run

time options to be set.

log for errors when running the Error Log Analysis. The default is seven days,

but can be changed from one to sixty days.

Ÿ Display Progress Indicators

This option allows the user to turn on or off the progress indicators when running

the Diagnostic Applications. The progress indicators are a popup box at the

bottom of the screen indicating the test being run (the default is on).

Chapter 9. Introducing Tasks and Service Aids 9-15

Ÿ Save Changes to the Database

This option allows the user to save any changes made to the run-time options.

Without saving the changes, any changes made are only applicable to that

session of diagnostics (the default is no).

Display Previous Diagnostic Results

Note: This service aid is only available when you load the diagnostics from a disk

drive or a network. However, on a CHRP system, this service aid is available when

you run the diagnostics in standalone mode because the results are stored in the

NVRAM.

Each time the diagnostics produce a service request number (SRN) to report a

problem, information about that problem is logged. The service representative can

look at this log to see which SRNs are recorded. This log also records the results of

diagnostic tests that are run in loop mode.

When this service aid is selected, information on the last problem logged is

displayed. The arrow keys can be used to look at information about previous

problems.

This information is not from the error log maintained by the AIX operating system.

The ASCII version of the Diagnostics Log is available in the

/etc/lpp/diagnostics/data/*.dat files.

Display Resource Attributes

This task displays the Customized Device Attributes associated with a selected

resource. This task is similar to running the lsattr -E -l <resource> command.

Display Service Hints

This service aid reads and displays the information in the CEREADME file from the

diagnostics media. This file contains information that is not in the publications for

this version of the diagnostics. It also contains information about using this particular

version of diagnostics.

Use the arrow keys to scroll through the information in the file.

Chapter 9. Introducing Tasks and Service Aids 9-21

Replace Controller

Use this selection when it is necessary to replace a controller in the array.

Flash SK-NET FDDI Firmware

This task allows the Flash firmware on the SysKonnect SK-NET FDDI adapter to be

updated.

Format Media

This task allows the selection of diskettes, hardfiles, or optical media to be formatted.

Each selection is described below.

Hardfile Attached to SCSI Adapter (non-RAID)

Ÿ Hardfile Format

Writes all of the disk. The pattern put on the disk is device dependent, i.e. some

drives may put all 0s, while some may put hexadecimal number 5F. No bad

block reassignment occurs

Ÿ Hardfile Format and Certify

Does the same function as Format. After the format is completed, Certify is run.

This certify reassigns all bad blocks encountered.

Ÿ Hardfile Erase Disk

This option can be used to overwrite (remove) all data currently stored in

user-accessible blocks of the disk. The Erase Disk option writes one or more

patterns to the disk. An additional option allows data in a selectable block to be

read and displayed on the system console.

To use the Erase Disk option, specify the number (0-3) of patterns to be written.

Select the patterns to be written; the patterns are written serially. That is, the

first pattern is written to all blocks. Then the next pattern is written to all blocks,

overlaying the previous pattern. A random pattern is written by selecting the

"Write random pattern?" option.

Note: The Erase Disk service aid has not been certified as meeting the

Department of Defense or any other organizations security guidelines.

9-22 7046 Model B50 User's Guide

The following steps should be followed if the data on the drive is to be

overwritten:

1. Use the "Erase Disk" selection to overwrite the data on the drive.

2. Do a format without certify.

3. Run a second pass of the erase disk selection.

For a newly installed drive, you can insure that all blocks on the drive are

overwritten with your pattern if you use the following procedure:

1. Format the drive.

2. Check the defect MAP by running the Erase Disk selection.

Note: If you use the "Format and Certify" option, there may be some blocks

which get placed into the grown defect MAP.

3. If there are bad blocks in the defect MAP, record the information presented

and ensure that this information is kept with the drive. This data is used later

when the drive is to be overwritten.

4. Use the drive as you would normally.

5. When the drive is no longer needed and is to be erased, run the same

version of the Erase Disk selection which was used in step 2.

Note: Using the same version of the service aid is only critical if there were

any bad blocks found in step 3.

6. Compare the bad blocks which were recorded with the drive in step 3 with

those which now appear in the grown defect MAP.

Note: If there are differences between the saved data and the newly

obtained data, then all sectors on this drive cannot be overwritten.

The new bad blocks are not overwritten.

7. If the bad block list is the same, continue running the service aid to overwrite

the disk with the chosen pattern(s).

This task may be run directly from the AIX command line. The following usage

statement describes the syntax of the command:

Usage:

diag -c -d <deviceName> -T "format [-sᑍ fmtcert | erase -a {read | write}]

[-F]"

Flag

Description

fmtcert

Formats and certifies the disk.

-F

Available in no-console mode only.

Force flag. Forces disk erasure even if all blocks cannot be erased due to

errors accessing grown defect map.

Chapter 9. Introducing Tasks and Service Aids 9-23

Note: Erase option in command line mode uses default values. To selectively read

or write, use diag in console mode.

Hardfile Attached to PCI SCSI RAID Adapter

This function formats the physical disks attached to a PCI SCSI RAID adapter. This

task may be run directly from the AIX command line. The following usage statement

describes the syntax of the command:

Optical Media

Ÿ Optical Media Initialize

Formats the media without certifying. This function does not reassign the

defective blocks or erase the data on the media. It provides a quick way of

formatting the media and cleaning the disk.

Note: It takes approximately 1 minute to format the media.

Ÿ Optical Media Format and Certify

Formats and certifies the media. This function reassigns the defective blocks

and erases all data on the media.

This task may be run directly from the AIX command line. The following usage

statement describes the syntax of the command:

Description

Diskette Format

This selection formats a diskette by writing patterns to it.

9-24 7046 Model B50 User's Guide

Generic Microcode Download

This service aid provides a means of executing a "generic" script from a diskette.

The intended purpose for this "generic" script is to load microcode to a supported

resource. This script is responsible for executing whatever program is required in

order to download the microcode onto the adapter or device.

This service aid is supported in both concurrent and standalone modes from disk,

LAN, or loadable media.

On entry, the service aid displays information about what it does. It then asks for a

Genucode diskette to be inserted into the diskette drive. The diskette must be in tar

format. The service aid then restores the script file genucode to the /tmp directory.

Then the script is executed. The script must at that point then pull off any other

needed files from the diskette. The script should then exec whatever program is

necessary in order to perform its function. On completion, a status code is returned,

and the user is returned to the service aid. The genucode script should have a # !

/usr/bin/ksh line at the beginning of the file. Return status of 0 should be returned if

the program was successful, else a non-zero status should be returned.

Local Area Network Analyzer

This selection is used to exercise the LAN communications adapters (Token-Ring,

Ethernet, and (FDDI) Fiber Distributed Data Interface). The following services are

available:

Ÿ Connectivity testing between two network stations. Data is transferred between

the two stations. This requires the user to input the Internet Addresses of both

stations.

Ÿ Monitoring ring (Token-Ring only). The ring is monitored for a period of time.

Soft and hard errors are analyzed.

Periodic Diagnostics

This selection provides a tool for configuring periodic diagnostics and automatic error

log analysis. A hardware resource can be chosen to be tested once a day, at a user

specified time. If the resource cannot be tested because it is busy, error log analysis

is performed. Hardware errors logged against a resource can also be monitored by

enabling Automatic Error Log Analysis. This allows error log analysis to be performed

every time a hardware error is put into the error log. If a problem is detected, a

message is posted to the system console and a mail message sent to the user(s)

belonging to the system group with information about the failure such as the Service

Request Number.

Chapter 9. Introducing Tasks and Service Aids 9-25

The service aid provides the following functions:

Ÿ Add or delete a resource to the periodic test list

Ÿ Modify the time to test a resource

Ÿ Display the periodic test list

Ÿ Modify the error notification mailing list

Ÿ Disable or Enable Automatic Error Log Analysis

PCI RAID Physical Disk Identify

This selection identifies physical disks connected to a PCI SCSI-2 F/W RAID

adapter.

This task may be run directly from the AIX command line. The following usage

statement describes the syntax of the command:

Usage

diag -c -d < pci RAID adapter > -T identify

Process Supplemental Media

Diagnostic Supplemental Media contains all the necessary diagnostic programs and

files required to test a particular resource. The supplemental is normally released

and shipped with the resource as indicated on the diskette label. Diagnostic

Supplemental Media must be used when the device support has not been

incorporated into the latest diagnostic CD-ROM.

This task processes the Diagnostic Supplemental Media. Insert the supplemental

media when prompted, then press Enter. After processing has occurred, go to the

Resource Selection list to find the resource to test.

Notes:

Ÿ This task is supported in Standalone Diagnostics only.

Ÿ Process and test one resource at a time.

Ÿ Do not process multiple supplementals at a time.

Run Diagnostics

The Run Diagnostics task invokes the Resource Selection List menu. When the

commit key is pressed, Diagnostics are run on all selected resources.

9-26 7046 Model B50 User's Guide

The procedures for running the diagnostics depend on the state of the diagnostics

run time options. See “Display or Change Diagnostic Run Time Options” on

page 9-15.

Run Error Log Analysis

The Run Error Log Analysis task invokes the Resource Selection List menu. When

the commit key is pressed, Error Log Analysis is run on all selected resources.

Run Exercisers

Note: The Run Exercisers task is only supported in Online Maintenance Mode on

CHRP systems.

This task provides a tool to troubleshoot intermittent system problems on AIX

Release 4.3.2 or later. This task provides an exerciser supervisor that controls the

selected exercisers.

When you select Run Exercisers from the Task Selection menu, the EXERCISER

SELECTION menu displays. Select the exerciser you want to run from this menu.

Each exerciser has other menus to set options for the exerciser.

Exerciser Commands (CMD)

Use the following commands as needed in the exerciser menus and reports. Not all

commands are available in each menu or report.

CMD

Description

Acknowledge an error.

View the AIX error log.

Page forward one page.

Return to Main Menu.

Refresh screen.

Enable or disable beep on error.

Exit system exerciser.

Acronyms

The following list describes acronyms used in the exerciser reports.

To toggle between two states (example Activate/Halt Devices), use the number of

the device.

Chapter 9. Introducing Tasks and Service Aids 9-27

Acronym Description

COE

Continue on error (use number to select).

Device has run the specified number of cycles and is not running.

The exerciser has been terminated by a signal.

Device has stopped with an error.

The device is hung.

Halt on error (use number to select).

Device is running.

HOE

Device is stopped.

Memory Exerciser

The memory exercisers are labeled memx, where x is a number for the exerciser.

Multiple exercisers can be active.

The memory exerciser requests as many memory buffers as possible from the AIX

operating system. The exerciser then fills the memory buffers with specified bit

patterns, then reads and compares the memory buffers to the specified bit patterns.

On systems with multiple processors a process is started for each processor. The

free memory space is split evenly between the available processors thus reducing

the time required to exercise all of the memory.

If the system is working properly, there are no compare errors. If a non-recoverable

memory error occurs, the system crashes. Recoverable memory errors are logged

by the AIX operating system.

The following items must be available to run this service aid:

Ÿ On-line diagnostics loaded in maintenance mode

Ÿ 128KB of free space in /etc/lpp/diagnostics/data

Ÿ The following commands must be available:

– vmstat

– lsps

– bootinfo

Save or Restore Hardware Management Policies

/etc/lpp/diagnostics/data/hmpolicies

Ÿ Restore Hardware Management Policies

This selection restores all of the settings for the hardware management policies

from the contents of the file:

/etc/lpp/diagnostics/data/hmpolicies

This service aid may be accessed directly from the AIX command line, by entering:

/usr/lpp/diagnostics/bin/uspchrp -a

SCSI Bus Analyzer

This service aid provides a means to diagnose a SCSI Bus problem in a free-lance

mode.

To use this service aid, the user should have an understanding of how a SCSI Bus

works. This service aid should be used when the diagnostics cannot communicate

with anything on the SCSI Bus and cannot isolate the problem. Normally the

procedure for finding a problem on the SCSI Bus with this service aid is to start with

a single device attached, ensure that it is working, then start adding additional

devices and cables to the bus ensuring that each one works. This service aid works

with any valid SCSI Bus configuration.

The SCSI Bus Service Aid transmits a SCSI Inquiry command to a selectable SCSI

Address. The service aid then waits for a response. If no response is received

within a defined amount of time, the service aid displays a timeout message. If an

error occurs or a response is received, the service aid then displays one of the

following messages:

Ÿ The service aid transmitted a SCSI Inquiry Command and received a valid

response back without any errors being detected.

Ÿ The service aid transmitted a SCSI Inquiry Command and did not receive any

response or error status back.

Ÿ The service aid transmitted a SCSI Inquiry Command and the adapter indicated

a SCSI bus error.

Ÿ The service aid transmitted a SCSI Inquiry Command and an adapter error

occurred.

Ÿ The service aid transmitted a SCSI Inquiry Command and a check condition

occur.

When the SCSI Bus Service Aid is entered a description of the service aid is

displayed.

Chapter 9. Introducing Tasks and Service Aids 9-29

Pressing the Enter key displays the Adapter Selection menu. This menu allows the

user to enter which address to transmit the SCSI Inquiry Command.

When the adapter is selected the SCSI Bus Address Selection menu is displayed.

This menu allows the user to enter which address to transmit the SCSI Inquiry

Command.

Once the address is selected the SCSI Bus Test Run menu is displayed. This

menus allows the user to transmit the SCSI Inquiry Command by pressing the Enter

key. The service aid then indicates the status of the transmission. When the

transmission is completed, the results of the transmission are displayed.

Notes:

Ÿ A Check Condition can be returned when there is nothing wrong with the bus

or device.

Ÿ AIX does not allow the command to be sent if the device is in use by another

process.

SCSI Device Identification and Removal

This service aid allows the user to choose a SCSI device or location from a menu

and to identify a device located in a server that uses a SCSI Enclosure Services

(SES) backplane.

The service aid also does the following:

Ÿ Generates a menu displaying all SCSI devices.

Ÿ Lists the device and all of it's sibling devices.

Ÿ List all SCSI adapters and their ports.

Ÿ List all SCSI devices on a port.

SCSD Tape Drive Service Aid

This service aid provides a means to obtain the status or maintenance information

from a SCSD tape drive. Only some models of SCSI tape drive are supported.

The service aid provides the following options:

Ÿ Display time since a tape drive was last cleaned.

The time since the drive was last cleaned is displayed onto the screen. In

addition, a message whether the drive is recommended to be cleaned is also

displayed.

9-30 7046 Model B50 User's Guide

Ÿ Copy a tape drive's trace table.

The trace table of the tape drive is written to diskettes or a file. The diskettes

must be formatted for DOS. Writing the trace table may require several diskettes.

The actual number of diskettes is determined by the size of the trace table.

Label the diskettes as follows:

'TRACE[x].DAT' (where 'x' is a sequential diskette number). The complete trace

table consists of the sequential concatenation of all the diskette data files.

When the trace table is written to a disk file, the service aid prompts for a file

name. The default name is: '/tmp/TRACE.<x>', where x is the AIX name of the

SCSD tape drive being tested.

Ÿ Display or copy a tape drive's log sense information.

The service aid provides options to display the log sense information to the

screen, to copy it to a DOS formatted diskette or to copy it to a file. The file

name "LOGSENSE.DAT" is used when the log sense data is written on the

diskette. The service aid prompts for a file name when the log sense data is

chosen to be copied to a file.

This service aid may be run directly from the AIX command line. The following usage

statement describes the syntax of the command (path is

/usr/lpp/diagnostics/bin/utape):

Usage:

utape [-h | -?] [-d <device>] [-n | -l | -t]

utape -c -d <device> [-v] {-n | {-l | -t} { -D | -f [<filename>]}}

Flag

-c

Description

Display time since drive was last cleaned.

Copy trace table.

-v

Verbose mode. If the -c flag is present, the information displays on the

screen. If the -n flag is present, the information about tape head cleaning

is printed.

Spare Sector Availability

This selection checks the number of spare sectors available on the optical disk. The

spare sectors are used to reassign when defective sectors are encountered during

normal usage or during a format and certify operation. Low availability of spare

sectors shows that the disk needs to be backed up and replaced. Formatting the

disk does not improve the availability of spare sectors.

This task may be run directly from the AIX command line. The following usage

statement describes the syntax of the command:

Usage:

diag -c -d < deviceName > -T chkspares

SSA Service Aids

This service aid provides tools for diagnosing and resolving problems on SSA

attached devices. The following tools are provided:

Ÿ Set Service Mode

Ÿ Link Verification

Ÿ Configuration Verification

Ÿ Format and Certify Disk

Update Disk Based Diagnostics

This service aid allows fixes (APARs) to be applied.

This task invokes the SMIT Update Software by Fix (APAR) task. The task allows

the input device and APARs to be selected. Any APAR can be installed using this

task.

9-32 7046 Model B50 User's Guide

Update System or Service Processor Flash

This selection updates the system or service processor flash for CHRP system units.

Further update and recovery instructions may be provided with the update. It is

necessary to know the fully qualified path and file name of the flash update image

file that was provided. If the flash update image file is on a diskette, the service aid

can list the files on the diskette for selection.

Refer to the update instructions, or the system unit's service guide to determine the

level of the system unit or service processor flash.

When run from online diagnostics, the flash update image file is copied to the /var

file system. If there is not enough space in the /var file system for the flash update

image file, an error is reported. If this occurs, exit the service aid, increase the size

of the /var file system and retry the service aid. After the file is copied, a warning

screen asks for confirmation to continue the update flash. Continuing the update

flash reboots the system. The system does not return to diagnostics. The current

flash image is not saved. After the reboot, the /var/update_flash_image can be

removed.

When running from standalone diagnostics, the flash update image file is copied to

the file system from diskette. The user needs to provide the image on a diskette

since the user does not have access to remote file systems or any other files that

are on the system. If enough space is not available, an error is reported stating

additional system memory is needed. After the file is copied, a warning screen asks

for confirmation to continue the update flash. Continuing the update flash reboots

the system. The current flash image is not saved.

The update_flash command can be used in place of this service aid. It is located in

the /usr/lpp/diagnostics/bin directory.

Attention: The update_flash command reboots the entire system. Do not use this

command if more than one user is signed onto the system.
