Booting the Red Hat Enterprise Linux Operating System
You can boot the Red Hat Enterprise Linux operating system on HP Integrity servers using either of these
methods:
• Choose a Red Hat Enterprise Linux entry from the EFI Boot Manager menu.
To load the Red Hat Enterprise Linux operating system 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 operating system using ELILO.EFI loader and
the elilo.conf file.
• Initiate the ELILO.EFI Linux loader from the EFI Shell.
Refer to “Access the EFI Shell.” on page 97 for details.
On a Red Hat Enterprise Linux boot device EFI System Partition, the full paths to the loader and
configuration files are:
\EFI\redhat\elilo.efi
\EFI\redhat\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.
Booting Red Hat Enterprise Linux from the EFI Shell
Use this procedure to boot Red Hat Enterprise Linux from the EFI Shell.
Step 1. Access the EFI Shell.
From the system console, choose the
EFI Shell entry from the EFI Boot Manager menu to access the
shell.
Step 2. Access the EFI System Partition for the Red Hat Enterprise Linux boot device.
Use the map EFI Shell command to list the file systems (fs0, fs1, and so on) that are known and
mapped.
To choose 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.
Step 3. Enter ELILO at the EFI Shell command prompt to launch the ELILO.EFI loader.
If needed, you can specify the loader’s full path by entering \EFI\redhat\elilo at the EFI Shell
command prompt.
Step 4. Allow the ELILO.EFI loader to proceed with booting the Red Hat Enterprise Linux kernel.
