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.

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)

   • Shut Down the OS (shutdown Command)

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

   You should now see the OpenBoot prompt. If the server is still not responding, perform the next steps.

5. If more than 10 minutes have passed since you typed the following command, do so again.

   -> set /HOST/bootmode script="setenv auto-boot? false"

6. Type:

   -> reset /System
   -> start /HOST/console
