20. Restart the system.
When the system powers on, it pauses at the Boot Option screen. Select one of the following
options:
• EFI Shell (built in). A command line interface that enables you to operate EFI commands or
create and run automounted scripts.
• EFI Boot Option Maintenance Menu enables you to select the order of the devices from
which you want the firmware to boot the OS. You can also configure the system to boot
from a configuration file.
• Security/Pass Menu enables you to add, change, and delete system administrator user
passwords.
You have seven seconds to change the boot option before the system boots to the default OS. To
highlight EFI Shell option, use the Up and Down arrow keys and press Enter.
Diagnostics
A suite of offline and online support tools are available to enable you, manufacturing, and field
support personnel to troubleshoot server problems. In general, if the operating system (HP-UX)
is already running, it is best not to shut it down. Use the online support tools.
If the OS cannot be booted, use the offline support tools to resolve the problem. The offline
support tools are available from the EFI partition. Once you resolve the problem preventing
booting, boot HP-UX, and use the online support tools for any further testing.
If it is not possible to reach the EFI from either the main disk or from LAN, you must troubleshoot,
using the visual fault indicators, console messages, and system error logs that are available.
