Introduction

The Network Server Diagnostic Utility allows you to verify basic capabilities 
of the Network Server 500 and Network Server 700. You can use this 
diagnostic utility when you are unable to load and run your operating 
system. You may want to print this document and keep it with your other 
manuals for future reference.

Both Network Server ships from the factory without an operating system or 
other software. Before or after installing the AIX¨ operating system, you can 
use the Network Server Diagnostic Utility to confirm the hardware 
configuration and to run basic tests. This document describes how to use the 
diagnostic utility. 

The Network Server Diagnostic Utility comes on a floppy disk. To keep this 
disk readily available, you may want to store it in the plastic envelope that is 
secured to the side of the server cabinet. 

For the latest version of the Network Server Diagnostic Utility software and 
documentation, click the Network Server button at the World Wide Web site 
http:/www.solutions.apple.com. 

Creating or Copying the Network Server Diagnostic Utility Disk

If you create a backup copy of the diagnostic utility, either by copying from 
another disk or by downloading it from the network, use a high-density, 1.4 
MB floppy disk formatted on a Mac OS computer. Copy the updated software 
to the disk and give the program file this name:

    diags

Verifying the Network Server Hardware Configuration

If you have just unpacked your Network Server and have set it up, you can  
run the Network Service Diagnostic Utility to establish that the basic 
hardware is functional. Check the server's front display panel (LCD) for 
information on server startup and to determine whether the server's Power-
On Self Test (POST) identified a problem. You may also determine certain 
basic information about the configuration of your Network Server by 
reviewing the front panel display status before the operating system starts 
up.  

To verify that SCSI devices have been properly attached, use the commands 
scsi-probe1 and scsi-probe2 described in the manual Setting Up the Network Server.

Starting Up the Network Server Diagnostic Utility

Before using the diagnostic utility, you need to set up server hardware 
according to the instructions in the manual Setting Up the Network Server. 
Your Network Server comes already setup to use the VGA monitor and ADB 
keyboard. If you want to run diagnostics using a serial terminal, see the 
instructions in Setting Up the Network Server. 

There are two options for starting up the diagnostic utility. The preferred 
option is to place the server in service mode. The other option, which you can 
use if the boot path names stored in NVRAM are corrupted, is to boot from 
Open Firmware .

To boot the Network Server Diagnostic Utility from service mode:

1. If AIX is running, enter this command:

    shutdown -r

2.  After the system completely shuts down, turn the front key to the left 
(service) position.

3.  Insert the Network Server Diagnostic Utility disk and press the reset 
button. 

The Network Server Utility starts up, displaying the hardware configuration 
and the Level One menu and prompt.

To boot the Network Server Diagnostic Utility from Open Firmware:

1. If AIX is running, enter this command:

    shutdown -r

2. While the system is resetting, or powering on, hold down these keys:

  Command-Option-O-F

Continue holding down these keys until the 0> prompt appears. If AIX is 
installed on your system and has run before, a Security> prompt appears. 

3. Enter this command: 

    login

The system displays ok followed by the 0> prompt. 

4.  If AIX is installed, the OF Password> prompt appears. Enter the AIX root 
password.

5. Insert the Network Server Diagnostic Utility disk. 

6. Enter this command to boot the diagnostic utility:

    boot fd:diags

The Network Server Utility starts up, then displays the server hardware 
configuration:

?   Help on Level One Menu.

Level One>

To run a Level One command, type the number that appears next to the 
command you want, then press RETURN. If the command includes a number 
in brackets, such as "Run complete system test [1] times," the bracketed 
number indicates the default. You can enter a different value by typing a 
different number after the command. For example, this runs the complete 
system test five times:

Level One>3 5

To display additional information about the commands, enter a ?.

Changing Default Test Preferences

These are the default Diagnostic Utility test preferences: 

Ą Run the selected test one time
Ą Stop testing when a failure is found
Ą Record each failure occurrence

To change these preferences, enter 6 at the Level 1> prompt. The Preferences 
Menu appears, enabling you to adjust the defaults:

Current preferences are:
   Test will repeat: 1
   Stop tests when a failure is found.
   Record each failure occurrence.

If you want to change the number of times each test runs, enter 8, followed 
by the number of test repetitions. For example, to automatically run each 
test three times:

 Preferences>8 3

Running All Diagnostic Utility Tests

To run all available tests, enter 3 at the Level One> prompt, followed by a 
number indicating how many times you want to run the test suite. For 
example, to run all tests twice:

Level One>3 2

Displaying Hardware Configuration Information

Server hardware configuration information displays at the time the 
Diagnostic Utility starts up. You can display configuration information any 
time by entering 1 at the Level One> prompt.

Displaying Power-On Self Test (POST) Results

Power-On Self Test (POST) software is stored in ROM (which is contained on a 
SIMM) and executes a number of tests every time the Network Server is 
started up. When the POST software detects a problem, the problem 
description is encoded and stored into a special memory location in non-
volatile RAM (NVRAM) where it is available for reference by Open Firmware, 
the Network Server Diagnostic Utility, and the operating system. The POST 
software also displays a description of the problem found on the front panel 
liquid crystal display (LCD). However, because a number of messages are 
displayed in sequence on the LCD, you may not be able to observe the error 
message unless the server halts. 

To display Power-On Self Test results reported by ROM, enter 2 at the Level 
One> prompt. These are the possible results:

Displaying the Error Summary Report

The Network Server Diagnostic Utility maintains an internal log of errors. 
Changing preferences affects how the log entries are updated. For example, if 
the preference option Record each failure occurrence is active, every error 
detected by the Network Server Diagnostic Utility is recorded in the internal 
log. If the preference option Do not record each failure occurrence is active, 
the error log contains only entries made before error logging was disabled.

Note that the Network Server Diagnostic Utility maintains a error log only 
while the utility is running. Exiting the diagnostic utility and restarting the 
Network Server erases the error log.

To display the error log, enter 4 a the Level One> prompt. Here are examples 
of the errors that might appear:

Exiting the Diagnostic Utility and Restarting the Network Server

Once you have finished running diagnostics, reboot the server by entering 5 
at the Level 1> prompt. The server ejects the diagnostic utility disk, and 
reboots the AIX operating system. 

If you want to run Open Firmware, hold down these keys while the server is 
restarting:
