Obtain the OpenBoot Prompt Under Various Conditions
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. |
- Set
the Oracle ILOM bootmode property.
-> set /HOST/bootmode script=”setenv auto-boot? false”
This setting ensures that you will reach the OpenBoot prompt rather than having the OS boot automatically.
- Choose the appropriate method to shutdown the OS and reach the OpenBoot prompt.
Refer to the linked procedures after you select a method.
