Performing Diagnostic Tests

This chapter describes how to use the Pc-Check diagnostic tests, provided on the service processor (ILOM or ELOM). If you are having a problem with your system, use the diagnostics to diagnose and solve it.

This chapter contains the following sections:

4.1 Pc-Check Diagnostics Overview

The Pc-Check diagnostics can test and detect problems on all motherboard components, drives, ports, and slots. This program can be accessed and executed only from the service processor.

Normally, if you encounter any hardware-related error message (such as memory errors or hard disk errors) on your workstation, you will run one of the following selections from the Diagnostics main menu:

Other selections on the Diagnostics main menu display information about the system, create disk partitions and display test results.

procedure icon  To Access the Pc-Check Diagnostics

1. Shut down the server.

For instructions, see Powering Off the Server.

2. Start the service processor and access the web interface.

3. Start the diagnostic program.

a. Select Remote Control => Remote Power Control => Boot from PCCheck.

b. Select Submit.

The system boots to the Pc-Check main menu.

a. Select Remote Control => Diagnostics.

b. Select an option from the drop-down menu.

Note - Choose Enabled or Extended only when requested by Sun support personnel.

c. Restart the system.

The system boots to the Pc-Check main menu,

The Pc-Check main menu offers the following selections:

Use the arrow keys on the keyboard to navigate through the diagnostics software, the Enter key to select a menu item, and the ESC key to exit a menu. Navigation instructions appear at the bottom of each screen.

To test a specific hardware component, select “Advanced Diagnostics Test.” See Advanced Diagnostics for details.

To run a test script, select “Immediate Burn-In Testing.” Sun provides three scripts that include a full test of all possible devices (full.tst), a quick test of devices (quick.tst), and a test that requires no user interaction (noinput.tst). See Performing Immediate Burn-In Testing for details.

To create your own test script, select “Deferred Burn-In Testing.” See Performing Deferred Burn-In Testing for details.

The following sections in this chapter describe the menu items and tests in detail.
