Using the OpenBoot PROM FCode Self-
Test
The Sun PCI-Express Dual Gigabit Ethernet Low-Profile adapter 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-all commands. 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. Before shutting down the OS and halting the system, ensure 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.
