What option will boot an LPAR directly from DVD media, without any user interaction required, when starting the LPAR from the Hardware Management Console (HMC)?

The Normal boot option boots the LPAR from its standard boot list, which typically points to the internal hard disk and does not target DVD media.

The 'Diagnostic with default boot list' HMC boot option instructs the system firmware to boot using the default device order, which includes the DVD or optical drive, and proceeds automatically without stopping for user input at the SMS menu or OpenFirmware prompt. This is the correct choice when an unattended, automated boot from DVD media is required. All other options either target the normal hard disk list or require interactive input at a firmware interface.

System Management Services (SMS) presents an interactive firmware menu requiring the administrator to manually select a boot device, which does not satisfy the no-user-interaction requirement.

The Open Firmware OK prompt drops the system into an interactive OpenFirmware command line, requiring the administrator to type boot commands manually before any device is booted.
