Booting the System

At times you may need to boot the system; for example, if you change the system's configuration or need to recover the operating system and software, you might need to boot your system.




	NOTE: Keep in mind that these tasks should be performed only by system management trained personnel or a Hewlett-Packard Service Representative as these procedures may result in loss of user data if performed inappropriately.

Examples given are representative of booting up from the disk drive (Primary Boot Path) and booting up from a tape (Alternate Boot Path).

After you power on the system, a screen similar to the following appears on the console screen:

If you need to boot from the disk, enter the following at the Main Menu prompt:

   Main Menu: Enter command or menu > BO Return

   Interact with IPL (Y or N)?> y Return




	NOTE: Booting from the primary path is the system default, therefore when `BO` is typed at the prompt, `BO PRI` is assumed.

The system responds with a screen similar to the following:
