Administering a System: Booting and Shutdown

Booting Systems

Chapter 5490

To have your computer boot itself when powered on or reset, the

autoboot ﬂag should be enabled.

To require action by an attendant to boot the computer, the autoboot

ﬂag should be disabled.

Setting the Value of the autoboot Flag The values of the autoboot and auto

search ﬂags can be set or changed in several ways:

• In the pre-boot environment, you can set them from the Boot Console

Handlers conﬁguration menu

• From a running HP-UX system you can use the setboot command

Setting Autoboot and Autosearch Flags Using the Boot Console Handler

Step 1. After powering on or resetting your computer (or nPartition) take control of the

boot process by hitting any key on the console keyboard so that

autoboot/autosearch will not boot the system automatically (if they are

currently enabled). The Boot Console Handler will display its main menu.

The Boot Console Handler (BCH) will display its main menu and prompt for a

command:

Main Menu: Enter command >

Step 2. Enter one of the following BCH commands (depending on your needs):

ON OFF Auto Boot The BCH tries the primary boot

path in nonvolatile memory; if it is

not bootable, the BCH interacts

with the user to obtain a bootable

device path

ON ON Auto

The BCH tries the primary boot

path; if it is not bootable, the BCH

searches to ﬁnd the ﬁrst device that

is bootable and boots from it.
