Obtain the OpenBoot Prompt Under Various Conditions
Obtain the OpenBoot Prompt Under Various Conditions
This procedure presents several ways to reach the OpenBoot prompt, in order of preference,
starting with a method that performs the most graceful shutdown of the OS. Some other
methods to perform a graceful shutdown to reach the OpenBoot prompt are described in
“Obtaining the OpenBoot Prompt” on page 38 .
This procedure assumes the default system console configuration. The method you use depends
on the state of the OS at the time you attempt to obtain the OpenBoot prompt.
Caution -
When possible, reach the OpenBoot prompt by performing a graceful shutdown of
the OS. Any other method used might result in the loss of server state data.
1. Shut down the OS at the host prompt.
From a shell or command tool window, type an appropriate OS command (for example,
shutdown
or
init 0
).
For details on shutting down the OS, see:
■
“Shut Down the OS (
init
Command)” on page 36

“Shut Down the OS (
shutdown
Command)” on page 37
2.
At the Oracle ILOM prompt, type:
-> set /HOST/bootmode script="setenv auto-boot? false"
This setting ensures that you reach the OpenBoot prompt rather than having the OS boot
automatically. This change applies only to a single reset and expires in 10 minutes if the power
on the host is not reset.
3. Type:
-> stop /System
The OpenBoot prompt (
ok
) appears.
If the OS was unresponsive and you were not able to reach the OpenBoot prompt, continue to
the next steps in this procedure.
4. At the Oracle ILOM prompt, type:
-> set /HOST send_break_action=break
-> start /HOST/console
