HP Integrity Server rx4640 manual Booting the Red Hat Enterprise Linux Operating System

Booting the Operating System

Booting and Shutting Down Linux

•bcfg boot dump — Displays all items in the boot options list for the server.

•bcfg boot rm # — Removes the item number specified by # from the boot options list.

•bcfg boot mv #a #b — Moves the item number specified by #a to the position specified by #b in the boot options list.

•bcfg boot add # file.efi "Description" — Adds a new boot option to the position in the boot options list specified by #. The new boot option references file.efi and is listed with the title specified by Description.

For example, bcfg boot add 1 \EFI\redhat\elilo.efi "Red Hat Enterprise Linux" adds a Red Hat Enterprise Linux item as the first entry in the boot options list.

Likewise, bcfg boot add 1 \efi\SuSE\elilo.efi "SLES 10" adds a SuSE Linux item as the first entry in the boot options list.

See the help bcfg command for details.

Step 4. Exit the console and management processor interfaces if you are finished using them.

Press Ctrl+B to exit the system console and return to the iLO MP Main Menu. To exit the iLO MP, enter X at the Main Menu.

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. For details, see “Access the EFI Shell.” on page 158.

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, enter 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.
