Booting the Operating System

Booting and Shutting Down Linux

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.

By default, the ELILO.EFI loader boots the kernel image and options specified by the default item in the elilo.conf file.

To interact with the ELILO.EFI loader, interrupt the boot process (for example, enter a space) at the ELILO boot prompt. To exit the loader use the exit command.

Booting the SuSE Linux Enterprise Server Operating System

You can boot the SuSE Linux Enterprise Server 10 operating system on HP Integrity servers using either of these methods:

Choose 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, 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. See “Booting SuSE Linux Enterprise Server from the EFI Shell” on page 159.

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, enter a space) at the ELILO boot prompt. To exit the ELILO.EFI loader, use the exit command.

Booting SuSE Linux Enterprise Server from the EFI Shell

Use this procedure to boot SuSE Linux Enterprise Server 10 from the EFI Shell.

Step 1. Access the EFI Shell.
