HP Integrity rx8640, HP 9000 rp8440 Server User Service Guide

\EFI\redhat\elilo.efi
\EFI\redhat\elilo.conf
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.
Procedure 18 Booting Red Hat Enterprise Linux (EFI Shell)
Use this procedure to boot Red Hat Enterprise Linux from the EFI Shell.
See “ACPI Configuration for Red Hat Enterprise Linux Must Be default” (page 108) for required
configuration details.
1. Access the EFI Shell.
From the system console, select the EFI Shell entry from the EFI Boot Manager menu to access
the shell.
2. Access the EFI System Partition for the Red Hat Enterprise Linux boot device.
Use the map EFI Shell command to list the file systems (fs0, fs1, and so on) that are known
and have been mapped.
To select a file system to use, enter its mapped name followed by a colon (:). For example,
to operate with the boot device that is mapped as fs3, enter fs3: at the EFI Shell prompt.
3. Enter ELILO at the EFI Shell command prompt to launch the ELILO.EFI loader.
If needed, you can specify the loader’s full path by entering \EFI\redhat\elilo at the
EFI Shell command prompt.
4. Allow the ELILO.EFI loader to proceed with booting the Red Hat Enterprise Linux kernel.
By default, the ELILO.EFI loader boots the kernel image and options specified by the default
item in the elilo.conf file.
To interact with the ELILO.EFI loader, interrupt the boot process (for example, type a space)
at the ELILO boot prompt. To exit the loader, use the exit command.
Booting SuSE Linux Enterprise Server
You can boot the SuSE Linux Enterprise Server 9 OS on HP Integrity servers using either of the
methods described in this section.
See “Shutting Down Linux” (page 110) for details on shutting down the SuSE Linux Enterprise Server
OS.
CAUTION:
ACPI Configuration for SuSE Linux Enterprise Server Must Be default
On cell-based HP Integrity servers, to boot the SuSE Linux Enterprise Server OS, an nPartition ACPI
configuration value must be set to default.
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 default, then SuSE Linux Enterprise Server
could panic.
To set the ACPI configuration for SuSE Linux Enterprise Server:
• At the EFI Shell enter the acpiconfig default command.
• Enter the reset command for the nPartition to reboot with the proper (default) configuration
for SuSE Linux Enterprise Server.
