Refer to “Shutting Down Linux” (page 119) 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.
Use either of the following 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 118) for
details.
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.
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
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 4-19 Booting SuSE Linux Enterprise Server (EFI Shell)
Use this procedure to boot SuSE Linux Enterprise Server 9 from the EFI Shell.
Refer to “ACPI Configuration for SuSE Linux Enterprise Server Must Be default” (page 118) 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 SuSE Linux Enterprise Server 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.
