Operating System Boot and Shutdown

Booting the Red Hat Linux Operating System

Appendix A

Booting the Red Hat Linux Operating System

You can boot the Red Hat Linux operating system on HP Integrity servers using either of the methods

described in this section.

See “Shutting Down Linux” on page 197 for details on shutting down the Red Hat Linux operating system.

CAUTION

ACPI Configuration for Red Hat Linux 3 Must Be “single-pci-domain”

On nPartition-capable HP Integrity servers, to boot the Red Hat Linux 3 operating system an

nPartition must have its ACPI configuration value set to

single-pci-domain

At the EFI Shell, enter the

acpiconfig

command with no arguments to list the current ACPI

configuration. If the

acpiconfig

value is not set to

single-pci-domain

, then Red Hat Linux

could panic; in this situation you must reconfigure

acpiconfig

to eliminate any bus address

conflicts and ensure all I/O slots have unique addresses.

To set the ACPI configuration for Red Hat Linux 3: at the EFI Shell enter the

acpiconfig

single-pci-domain

command, and then enter the

reset

command for the nPartition to reboot

with the proper (

single-pci-domain

) configuration for Red Hat Linux 3.

Use either of these methods to boot Red Hat Linux:

•

Select a Red Hat Linux entry from the EFI Boot Manager menu.

To load the Red Hat Linux operating system at the EFI Boot Manager menu, select its entry from the list

of boot options.

Selecting a Linux entry from the boot options list boots the operating system using

ELILO.EFI

loader and

the

elilo.conf

file.

•

Invoke the

ELILO.EFI

Linux loader from the EFI Shell.

See the procedure “Red Hat Linux Operating System Booting from the EFI Shell” on page 190 for details.

On a Red Hat Linux boot device EFI System Partition, the full paths to the loader and configuration files

are:

\EFI\redhat\elilo.efi

\EFI\redhat\elilo.conf

After selecting the filesystem for the boot device (for example,

fs0:

) you can invoke the Linux loader from

the EFI Shell prompt by entering the full path for the

ELILO.EFI

loader.

By default the

ELILO.EFI

loader boots Linux using the kernel image and parameters specified by the default

entry in the

elilo.conf

file on the EFI System Partition for the boot device.

To interact with the

ELILO.EFI

loader, interrupt the boot process (for example, type a space) at the

ELILO

boot

prompt. To exit the

ELILO.EFI

loader use the

exit

command.
