Sun Microsystems 6U manual Using the OpenBoot PROM FCode Self-Test

Using the OpenBoot PROM FCode Self-Test

The Sun Quad FastEthernet adapter’s self-test verifies the correct operation of the adapter and identifies any hardware problems with the adapter. The self-test is a suite of tests that reside in the adapter’s FCode PROM.

You can only invoke the FCode self-test diagnostics using the OpenBoot PROM test or test-allcommands. In order to access the OpenBoot PROM, you must shut down and halt your system to display the ok prompt.

You can use the adapter’s self-test any time you want to determine the status of the hardware. If you encounter an error while running the diagnostic test, the self-test displays appropriate error messages.

Note –Although the self-test does not require the adapter’s interface to be connected to an active network, you will see failing error messages if it is not connected.

▼To Run the FCode Self-Test Diagnostic

For more information about the OpenBoot commands (including test) in this section, refer to the OpenBoot Command Reference manual.

1.Make sure that all significant application and network activity on the server has stopped.

2.Follow the appropriate procedures, as documented in the system’s service manual, to shut down and halt the system.

Refer to the system’s documentation for the complete shutdown procedure.

After shutting down the system, you should see the OpenBoot PROM’s ok prompt on the system console.

3.At the ok prompt, set the auto-boot?configuration variable to false.

ok setenv auto-boot? false
