HP Integrity rx8620 Server User Service Guide

2. Access the EFI System Partition for the Red Hat Linux boot device.
To list the filesystems (fs0, fs1, and so on) that are known and have been mapped, use the
map EFI Shell command.
To select a filesystem 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. To launch the ELILO.EFI loader, enter ELILO at the EFI Shell command prompt.
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 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, enter a
space) at the ELILO boot prompt.
5. To exit the loader use the exit command.
Booting the SuSE Linux Enterprise Server Operating System
You can boot the SuSE Linux Enterprise Server 9 operating system on HP Integrity servers using
either of the methods described in this section.
See “Shutting Down Linux” (page 215) for details on shutting down the SuSE Linux Enterprise
Server operating system.
CAUTION:
ACPI Configuration for SuSE Linux Enterprise Server Must Be “default” On nPartition-capable
HP Integrity servers, to boot the SuSE Linux Enterprise Server operating system an nPartition
must have its ACPI configuration value 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, 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, and then enter the reset command for the nPartition to
reboot with the proper (default) configuration for SuSE Linux Enterprise Server.
To boot SuSE Linux Enterprise Server, use either of these methods:
• Select a SuSE Linux Enterprise Server entry from the EFI Boot Manager menu.
To load the SuSE Linux Enterprise Server 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.
For details, see “SuSE Linux Enterprise Server Operating System Booting from the EFI Shell”
(page 212).
On a SuSE Linux Enterprise Server boot device EFI System Partition, the full paths to the
loader and configuration files are:
\efi\SuSE\elilo.efi
\efi\SuSE\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.
