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.
