Diagnosing Server Problems With the Bootable Diagnostics CD

This Bootable Diagnostics CD is designed so that the server will boot from the CD. This CD boots and starts SunVTS software. Diagnostic tests run and write output to log files that the service technician can use to determine the problem with the server.


To use the diagnostics CD you must have a keyboard, mouse, and monitor attached to the server on which you are performing diagnostics, or available through a remote KVM.

Using the Bootable Diagnostics CD

To use the diagnostics CD to perform diagnostics:

1. With the server powered on, insert the CD into the DVD-ROM drive.

2. Reboot the server, and press F2 during the start of the reboot so that you can change the BIOS setting for boot-device priority.

3. When the BIOS Main menu appears, navigate to the BIOS Boot menu.

Instructions for navigating within the BIOS screens appear on the BIOS screens.

4. On the BIOS Boot menu screen, select Boot Device Priority.

The Boot Device Priority screen appears.

5. Select the DVD-ROM drive to be the primary boot device.

6. Save and exit the BIOS screens.

7. Reboot the server.

When the server reboots from the CD in the DVD-ROM drive, the Solaris operating system boots and SunVTS software starts and opens its first GUI window.

8. In the SunVTS GUI, press Enter or click the Start button when you are prompted to start the tests.

The test suite runs until it encounters an error or the test is completed.

Note - The CD takes approximately nine minutes to boot.

9. When SunVTS software completes the test, review the log files generated during the test.

SunVTS provides access to four different log files.

a. Locate the log file.

The following files are located in /var/sunvts/logs:

The following message log is located in /var/adm/:

a. Click the Log button.

The Log file window appears.

b. Specify the log file that you want to view by selecting it from the Log file window.

The content of the selected log file appears in the window.

c. With the three lower buttons, you can perform the following actions:

Note - If you want to save the log files: When you use the Bootable Diagnostics CD, the server boots from the CD. Therefore, the test log files are not on the server’s hard disk drive and they will be deleted when you power cycle the server. To save the log files, you must save them to a removable media device or FTP them to another system.
