nPartition Administrator's Guide, Second Edition

Refer to “Shutting Down Linux” (page 134) for details on shutting down the SuSE Linux Enterprise
Server OS.
CAUTION:
ACPI Configuration for SuSE Linux Enterprise Server Must Be single-pci-domain or default On
cell-based HP Integrity servers, to boot the SuSE Linux Enterprise Server OS an nPartition must
have its ACPI configuration value set to single-pci-domain or default.
• On HP rx7620 servers, rx8620 servers, or Integrity Superdome (SD16A, SD32A, SD64A), the
ACPI configuration must be set to single-pci-domain.
• On HP rx7640 servers, rx8640 servers, or Integrity Superdome (SD16B, SD32B, SD64B), the
ACPI configuration 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 correctly then SuSE Linux Enterprise Server
could panic.
To set the ACPI configuration for SuSE Linux Enterprise Server: at the EFI Shell enter the
acpiconfig value command, where value is either single-pci-domain (for rx7620 and
rx8620 servers) or default (for rx7640 and rx8640 servers). Then enter the reset command
for the nPartition to reboot with the proper configuration for SuSE Linux Enterprise Server.
Use either of these methods to boot SuSE Linux Enterprise Server:
• Choose a SuSE Linux Enterprise Server entry from the EFI Boot Manager menu.
To load the SuSE Linux Enterprise Server OS at the EFI Boot Manager menu, choose its entry
from the list of boot options.
Choosing a Linux entry from the boot options list boots the OS using ELILO.EFI loader
and the elilo.conf file.
• Initiate the ELILO.EFI Linux loader from the EFI Shell.
Refer to the procedure “Booting SuSE Linux Enterprise Server (EFI Shell)” (page 133) 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 choosing the file system for the boot device (for example, fs0:) you can initiate 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.
Procedure 5-24 Booting SuSE Linux Enterprise Server (EFI Shell)
Use this procedure to boot SuSE Linux Enterprise Server from the EFI Shell.
Refer to “ACPI Configuration for SuSE Linux Enterprise Server Must Be single-pci-domain or
default” (page 133) for required configuration details.
1. Access the EFI Shell.
From the system console, choose the EFI Shell entry from the EFI Boot Manager menu to
access the shell.
