Entering the ok Prompt
This procedure provides several ways of reaching the ok prompt. The methods are
not equally desirable. For details about when to use each method, see “About the ok
Prompt” on page 33.
Caution – Dropping the Sun Fire V445 server to the ok prompt suspends all
application and OS software. After you issue firmware commands and run
firmware-based tests from the ok prompt, the system might not be able to resume
where it left off.
