How to Put the Server in Service Mode

Before You Begin

In normal mode, firmware-based diagnostic tests can be configured (and even disabled) to expedite the server’s startup process. If you have set OpenBoot configuration variables to bypass diagnostic tests, you can always reset those variables to their default values to run tests.

Alternatively, putting the server into service mode according to the following procedure ensures that POST and OpenBoot Diagnostics tests do run during startup.

For a full description of service mode, see:

■OpenBoot PROM Enhancements for Diagnostic Operation

This document is included on the Sun Fire V490 Documentation CD.

What to Do

1.Set up a console for viewing diagnostic messages.

Access the system console using an ASCII terminal or tip line. For information on system console options, see “About Communicating With the System” on page 69.

2.Do one of the following, whichever is more convenient:

■Set the server’s system control switch to the Diagnostics position.

■Set the service-mode?OpenBoot configuration variable to true. Type:

ok setenv service-mode? true

If either of these switches is set as described, the next reset will cause diagnostic tests to run at Sun-specified coverage, levels, and verbosity.

3. Type:

ok reset-all
