How to Use OpenBoot Information

Commands

This section explains how to run OpenBoot commands that display different kinds of system information about a Sun Fire V490 server. To find out what these commands tell you, see “Other OpenBoot Commands” on page 90, or refer to the appropriate man pages.

Before You Begin

As long as you can reach the ok prompt, you can use OpenBoot information commands. This means the commands are usually accessible even if your system cannot boot its operating system software.

What to Do

1.If necessary, halt the system to reach the ok prompt.

How you do this depends on the system’s condition. If possible, you should warn users and shut down the system gracefully. For information, see “About the ok Prompt” on page 49.

2.Decide what kind of system information you want to display.

For more information, see “Other OpenBoot Commands” on page 90.
