Caution – Forcing the server to the ok prompt suspends all application and
operating system 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.
If at all possible, back up system data before starting this procedure. Also exit or
stop all applications and warn users of the impending loss of service. For
information about the appropriate backup and shutdown procedures, see Solaris
system administration documentation.
▼ To Obtain the ok Prompt
1. Decide which method you need to use to reach the ok prompt.
See “OpenBoot ok Prompt” on page 12 for details.
