Booting The Suse Linux Enterprise Server Operating System - HP Integrity Superdome SX1000 User Manual

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" on page 197 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, 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, and then enter the reset command for the nPartition to
reboot with the proper (default) configuration for SuSE Linux Enterprise Server.
Use either of these methods to boot SuSE Linux Enterprise Server:
• 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.
See the procedure "SuSE Linux Enterprise Server Operating System Booting from the EFI Shell" on
page 192 for details.
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.
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.
