Booting Red Hat Enterprise Linux
You can boot the Red Hat Enterprise Linux OS on HP Integrity servers using either of the methods
described in this section.
Refer to “Shutting Down Linux” (page 119) for details on shutting down the Red Hat Enterprise
Linux OS.
CAUTION:
ACPI Configuration for Red Hat Enterprise Linux Must Be default On cell-based HP Integrity
servers, to boot the Red Hat Enterprise Linux OS, an nPartition ACPI configuration must be
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 Red Hat Enterprise Linux
could panic. In this situation, you must reconfigure
acpiconfig
to eliminate any bus address
conflicts and ensure all I/O slots have unique addresses.
To set the ACPI configuration for Red Hat Enterprise Linux:
• At the EFI Shell enter the
acpiconfig default
command.
• Enter the
reset
command for the nPartition to reboot with the proper (
default
)
configuration for Red Hat Enterprise Linux.
Use either of the following methods to boot Red Hat Enterprise Linux:
• Choose a Red Hat Enterprise Linux entry from the EFI Boot Manager menu.
To load the Red Hat Enterprise Linux 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 Red Hat Enterprise Linux (EFI Shell)” (page 117) 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 Red Hat Enterprise Linux boot device EFI System Partition, the full paths to the loader
and configuration files are:
