Purpose

This document provides information on how to execute a diagnostics check on a NN3800 or NN4500.

Troubleshooting Steps

NOTE: Diagnostics should be run from a serial console port connection to the system. Once you boot the diags image you will no longer be able to SSH or telnet into the system. Be sure to have a console connection preferably with a terminal emulation program that will allow you to capture data to a file.

First, check to see that you have an appropriate diagnostoics image file on the system:

Log into the system Console port:

To execute diagnostics on an NN4500 running older code, you may need to first login to the shell to determine the name of the diags file that have been preinstalled in the /code/images directory:

ACMELAB# shell
Password: vxworks
->
-> ll "/code/images"

Listing Directory /code/images:
drwxrwxrwx 1 0 0 4096 Jul 24 19:07 ./ d
rwxrwxrwx 1 0 0 4096 Jan 1 1970 ../
-rwxrwxrwx 1 0 0 12979821 Jul 24 19:07 nnCX600p8.gz
-rwxrwxrwx 1 0 0 3120042 Jul 24 19:07 nnCX_diags104.gz
value = 0 = 0x0
-> exit
Au revoir!
ACMELAB#

In either case, once you have the diagnostics image identified, change the bootparameters to use this filename to boot from

ACMELAB# config term
SD3-14(configure)# b

'.' = clear field; '-' = go to previous field; q = quit

boot device : eth0
processor number : 0

[diag_proc] -> test all

Testing Processor Module Tests (proc)

001: Flash /boot Check Disk Status Test------------->passed
002: Flash /boot Disk Size Test--------------------->passed
003: Flash /code Check Disk Status Test------------->passed
004: Flash /code Disk Size Test--------------------->passed
...
...

The testing will go on until all system components are tested, and the test result summary will be posted once completed. Then type 'reboot' at the diag_proc prompt, interrupt the boot sequence with space bar to change the image name back to whatever it was before (nnCX600p8.gz in this example), and boot normally.

Notice that last diags images are tar files (nnCX_diagsxxx.tar), systems require a minimum bootloader version to be able to load such kind of images. Minimum bootloader date should be Jun 21st, 2011, in case that system is running a previous version, bootloader should be upgraded before loading diags image.

Duration of test: It may take approximately one hour for the full set of tests to run, depending on the system configuration.
