▼ Running the Ethernet FCode Selftest Diagnostic
To run the ethernet diagnostics, you must first bring the system to a stop at the
OpenBoot prompt after issuing a reset. If you do not reset the system, the diagnostic
tests may cause the system to hang.
For more information about the OpenBoot commands in this section, refer to the
OpenBoot 3.x Command Reference manual.
1. Shut down the system.
Use the standard shut down procedures described in Solaris 2.x Handbook for SMCC
Peripherals.
2. At the ok prompt, set the auto-boot? configuration variable to false.
3. Reset the system.
4. Type show-devs to display the list of devices.
You should see lines in the list of devices, similar to the example below, specific to
the Sun Quad FastEthernet PCI adapter:
In this example, the SUNW,qfe@x,1 entries identify the device paths to the four
Ethernet channels.
5. Type the following to put the OpenBoot PROM into diagnostic mode:
ok setenv auto-boot? false
ok reset-all
ok show-devs
