Finishing the Installation  
Your server hardware is set up, and you are ready to learn about your system and  
make backup copies of important software. The order in which you do these tasks is  
up to you. Use the following checklist as a guide:  
Ø Record your identification numbers  
Your server has important identification information that you might need if you  
have it serviced.  
Appendix A, “System Records” shows where to find these numbers, and  
provides space to record and retain this information.  
Ø Install the operating system  
If AIX is preinstalled in your server, or if you plan to install AIX yourself, refer to  
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.

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)  
Ÿ Metal  
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.  
Chapter 2. Using the Server 2-13  
Cleaning the Mouse

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  
labeled metal shutter first. Push the diskette into the drive until you hear a click.  
The click indicates that the diskette is securely in position in the drive.  
To unload the diskette, push the diskette-unload button. The diskette unloads  
partially from the drive. Remove the diskette.

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.  
2-18 7046 Model B50 User's Guide  
Performing an Emergency Eject  
Note: Execute the following procedure only in an emergency, such as when the tray  
does not open if the unload button has been pressed.  
1. Insert a small diameter rod, such as a straightened paper clip, into the  
emergency eject hole. (Refer to the illustration on page 2-17 for the location of  
the emergency eject access.)  
2. Push in the tool until you feel some resistance.  
3. Maintain a small amount of pressure on the rod while pulling on the tray with  
your fingernail.  
4. Pull the tray open and remove the disc.  
Note: Normally the tray makes a ratcheting sound when you pull it open using  
the above procedure.

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.

Set Power On Password: Setting a power-on password helps protect  
information stored in your server. You can use any combination of up to eight  
characters (A–Z, a–z, and 0–9) for your password. The password you type is not  
displayed on the screen. Press Enter when you are finished; you must type the  
password again for verification.  
If you previously had set a power-on password and wanted to remove it, select  
Remove Power-On Password.  
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 “Enabling and Disabling the  
Power-On Password” 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 your 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.  
3-30 7046 Model B50 User's Guide  
Set 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 your  
server's system board. See Chapter 4, “Installing and Removing Options” on  
page 4-1 to locate and change the password-enabling jumper.  
If the password-enabling jumper has been changed, select Set privileged-access  
password to set and verify the privileged-access password.  
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. Removing the battery does not affect the  
state of the privileged-access password.  
If you previously had set a privileged-access password and want to remove it, select  
Remove Privileged-Access Password.

If you have installed (or removed) options previously, you might be able to perform  
some activities without detailed instructions. These activities are listed in the “Before  
you begin” boxes of the procedures.  
Before you install or remove an option, be sure you are familiar with the safety  
procedures and component-handling guidelines described in “Safety Considerations”  
on page 4-2. These precautions and guidelines help you work safely with your  
server or options.

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  
Removing the Cover  
Before you begin:  
Ÿ Read “Safety Considerations” on page 4-2 and “Handling Static Sensitive  
Devices” on page 4-3.  
1. Remove any media (diskette or CD) from the drives.  
2. Shut down programs as described in your operating system documentation.  
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  
6. Make a note of where the other cables and cords are connected to the back of  
the server, then disconnect them.  
7. Unscrew the two front thumbscrews that secure the server to the rack.  
8. Gently slide the server out of the rack until you encounter the spring detents.  
9. Release the spring detents by pressing in on each spring detent on both sides of  
the server at the same time. While pressing in, continue to slowly slide the  
server out of the rack until the spring detents are completely out of the rack.

This allows unattended restart after AC power has been interrupted by a power  
outage, for example.  
When the automatic power-up capability is enabled, the server turns on as soon as  
AC power is applied, even if the server was not turned on before the interruption.  
Your server arrives from the factory with the automatic power-up feature disabled.  
Note: If the power-on password is set, then the server still turns on but does not  
boot unless the Remote Mode is enabled. To set the power-on password  
and Remote Mode, see Chapter 3, “Using System Management Services.”  
To enable the automatic power-up feature, do the following:

Installing Memory Modules  
You can increase the amount of memory in your server by installing memory  
modules. Your server uses 168-pin, 3.3 volt, Error Correcting Code (ECC) dual  
inline memory modules (DIMMs) to increase server memory.  
You install memory modules into connectors inside the server. You can install up to  
1024MB of ECC memory. (1MB equals approximately 1000000 bytes.) The  
memory module sizes for your server include 256MB, 128MB, 64MB, 32MB, and  
16MB. The available speed for these memory modules is 60 ns.  
Before you begin:  
Ÿ Read “Safety Considerations” on page 4-2 and “Handling Static Sensitive  
Devices” on page 4-3.  
Ÿ Remove the server and cover (see “Removing the Cover” on page 4-4).  
Note: When installing memory modules, install the new modules into the first  
available connector, starting at slot 4.  
1. Locate the memory module connectors.  
To locate the four memory module connectors, use the following figure:  
2. Remove any adapters that are blocking the memory module connectors (see  
“Removing Adapters” on page 4-26).  
4-16 7046 Model B50 User's Guide  
3. Touch the static-protective package containing the option to any unpainted metal  
surface on the server, then remove the option from the package.  
4. Install the first memory DIMM in slot 4, the second in slot 3, and so forth.  
Ensure that the locking tabs are opened prior to installing the memory DIMM.  
5. The memory modules are keyed so that they can only be inserted one way.  
Align the memory module notches with the keys in the memory connector.  
Chapter 4. Installing and Removing Options 4-17  
6. Push down on the memory module until the locking tabs lock the memory  
module into the connector. (Do not attempt to move the locking tabs yourself.  
They lock automatically when you have fully inserted the memory module.)  
Attention: Inserting the memory module at an angle may cause damage.  
7. Inspect each memory module and ensure that the module is fully inserted into  
the socket.

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.

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.  
5. When DIAGNOSTIC OPERATING INSTRUCTIONS screen is displayed, follow  
the displayed instructions to check out the desired resources.  
6. When testing is complete, use the F3 key to return to DIAGNOSTIC  
OPERATING INSTRUCTIONS. Then press the F3 key again to return to the AIX  
operating system prompt.  
7. Press Ctrl-D to log off from root or superuser.  
Standalone Diagnostic Operation  
Standalone Diagnostics provide a method to test the system when the Online  
Diagnostics are not installed and a method of testing the disk drives that cannot be  
tested by the Online Diagnostics.  
No Error Log Analysis is done by the Standalone Diagnostics.  
The CD-ROM drive and the SCSI controller that controls it cannot be tested by the  
Standalone Diagnostics.  
Running the Standalone Diagnostics  
To run Standalone Diagnostics in service mode, take the following steps:  
1. Verify with the system administrator and system users that the system unit may  
be shut down, then stop all programs including the AIX operating system. (Refer  
to the AIX operating system documentation shutdown command information.)  
2. Remove all tapes, diskettes, and CD-ROMs.  
3. Insert the Diagnostic CD-ROM into the CD-ROM drive.  
4. Turn off the system unit.  
5. Turn the power on.  
a. After the Keyboard indicator appears, press 5 on the keyboard to indicate that  
diagnostics are to be loaded.  
b. Enter any requested passwords.  
c. Follow any instructions to select a console.  
Chapter 5. Using the Online and Standalone Diagnostics 5-13  
6. After the diagnostic controller loads, DIAGNOSTIC OPERATING  
INSTRUCTIONS appear on the console display.

5-14 7046 Model B50 User's Guide  
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:  
00  
01  
02  
03  
04  
05  
xy  
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 7. Using the System Verification Procedure  
The system verification procedure is used to check the system for correct operation.  
If you are analyzing a hardware problem, see Chapter 8, Determining Hardware  
Problems.  
Step 1. Considerations before Running This Procedure  
Notes:  
1. If this system unit is directly attached to another system unit or attached to a  
network, make sure that communications with the other system unit are stopped.  
2. This procedure requires use of all of the system resources. No other activity can  
be running on the system while you are doing this procedure.  
Ÿ This procedure requires a display connected to the video port or an ASCII  
terminal attached to the S1 port.  
Ÿ Before starting this procedure, stop all programs and the operating system.  
Ÿ This procedure runs the Online Diagnostics in Service mode or Standalone  
Diagnostics. If the Online Diagnostics are installed, they should be run. See the  
operator manual for your type of ASCII terminal to find the key sequences you  
need to respond to the diagnostics.  
Ÿ If you need more information about diagnostics, see Chapter 5, Using the Online  
and Standalone Diagnostics.  
Ÿ If a console display is not selected, the diagnostics stop. The instructions for  
selecting a console display are displayed on all of the graphic displays and any  
terminal attached to the S1 port. Follow the instructions to select a console  
display.  
Ÿ Go to Step 2.

Chapter 8. Determining Hardware Problems  
This chapter provides information on using Standalone or Online Diagnostics to help  
you solve hardware problems. In addition, it provides a list of error codes and  
recommended actions you can take to resolve the problem before contacting a  
service representative.  
Problem Determination Using the Standalone or Online Diagnostics  
Use this procedure to obtain a service request number (SRN) when you are able to  
load the Standalone or Online Diagnostics. If you are unable to load the Standalone  
or Online Diagnostics, go to “Problem Determination When Unable to Load  
Diagnostics” on page 8-11. The service organization uses the SRN to determine  
which field replaceable units (FRUs) are needed to restore the system to correct  
operation.  
Step 1. Considerations before Running This Procedure  
Note: See the operator manual for your ASCII terminal to find the key sequences  
you need to respond to the diagnostic programs.  
Ÿ The diagnostics can use a display connected to the video port or an ASCII  
terminal attached to serial port 1.  
Ÿ This procedure asks you to select the type of diagnostics you want to run. If you  
need more information about the types, see “Standalone and Online Diagnostics  
Operating Considerations” on page 5-1.

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.

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

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 9-11  
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.)

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

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.

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:

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.

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

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]  
or  
utape -c -d <device> [-v] {-n | {-l | -t} { -D | -f [<filename>]}}  
Flag  
-c  
Description  
Run the service aid without displaying menus. The return code indicates  
success or failure. The output is suppressed except for the usage  
statement and the numeric value for hours since cleaned (if -n and -D  
flags are used).  
-D  
-f  
Copy data to diskette.  
Copy data to the filename given after this flag or to a default filename if  
no name is specified.  
-h, -?  
-l  
Display a usage statement and/or return code. If the -c flag is present,  
only the return code displays to indicate the service aid did not run. If the  
-c isn't used, a usage statement displays and the service aid exits.  
Display or copy log sense information.  
Chapter 9. Introducing Tasks and Service Aids 9-31  
-n  
-t  
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.
