HP Integrity Superdome and 9000 Superdome sx2000 manual Shutting Down Linux

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 141) 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.

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\SuSE\elilo at the EFI Shell command prompt.

4.Allow the ELILO.EFI loader to proceed with booting the SuSE 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, type a space) at the ELILO boot prompt. To exit the loader, use the exit command.

Shutting Down Linux

Use the shutdown command to shut down Red Hat Enterprise Linux or SuSE Linux Enterprise Server.

The Red Hat Enterprise Linux and SuSE Linux Enterprise Server shutdown command includes the following options:

-hHalt after shutdown.

On cell-based HP Integrity servers, this either powers down server hardware or puts the nPartition into a shutdown for reconfiguration state.

Use the PE command at the management processor Command Menu to manually power on or power off server hardware, as needed.

-rReboot after shutdown.

-cCancel an already running shutdown.
