where boot-device-path is the path to a valid device from which to boot.
Caution - If you plan to use a boot disk that is part of an FC array to install the OS in a hands-free manner, you must change the device path before you execute this command. In the device path, you must replace disk@ with sdd@. For example, the following device path, /pci@312/pci@1/SUNW,emlxs@0/fp@0,0/disk@w5000cca0172afb6d,0:a should be: /pci@312/pci@1/SUNW,emlxs@0/fp@0,0/ssd@w5000cca0172afb6d,0:a |
