●To set OpenBoot configuration variables that accept multiple keywords, separate keywords with a space:

ok setenv post-trigger power-on-reset error-reset

post-trigger = power-on-reset error-reset

Note – The test-argsvariable operates differently from other OpenBoot configuration variables. It requires a single argument consisting of a comma- separated list of keywords. For details, see “Controlling OpenBoot Diagnostics Tests” on page 85.

What Next

Changes to OpenBoot configuration variables usually take effect upon the next reboot.

Reference for Choosing a Fault Isolation Tool

This section helps you choose the right tool to isolate a failed part in a Sun Fire V490 system. Consider the following questions when selecting a tool.

1.Have you checked the LEDs?

Certain system components have built-in LEDs that can alert you when that component requires replacement. For detailed instructions, see “How to Isolate Faults Using LEDs” on page 172.

2.Does the system have main power?

If there is no main power to the system, standby power from the SC card may enable you to check the status of some components. See “About Monitoring the System” on page 101.

3.Does the system boot?

■If the system cannot boot, you have to run firmware-based diagnostics that do not depend on the operating system.

■If the system can boot, you should use a more comprehensive tool. The typical fault isolation process is illustrated in FIGURE 10-1.
