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: -h Halt 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. -r Reboot after shutdown. -c Cancel an already running shutdown. time When to shut down (required). You can specify the time option in any of the following ways: • Absolute time in the format hh:mm, in which hh is the hour (one or two digits) and mm is the minute of the hour (two digits). • Number of minutes to wait in the format +m, in which m is the number of minutes. • now to immediately shut down; this is equivalent to using +0 to wait zero minutes. Refer to the shutdown(8) Linux manpage for details. Also refer to the Linux manpage for the poweroff command. NOTE: On HP rx7620, rx7640, rx8620, and rx8640 servers, you can configure the nPartition behavior when an OS is shut down and halted (shutdown -h or poweroff). The two options are to have hardware power off when the OS is halted or to have the nPartition be made inactive (all cells are in a boot-is-blocked state). The normal behavior for Red Hat Enterprise Linux or SuSE Linux Enterprise Server shut down and halt is for the nPartition to be made inactive. For details, refer to "ACPI Softpowerdown Configuration-OS Shutdown Behavior" (page 92). Procedure 4-20 Shutting Down Linux From the command line for Red Hat Enterprise Linux or SuSE Linux Enterprise Server, issue the shutdown command to shut down the OS. 1. Log in to Linux running on the system you want to shut down. Log in to the management processor (MP) for the server and use the Console menu to access the system console. Accessing the console through the MP enables you to maintain console access to the system after Linux has shut down. Booting and Shutting Down Linux 119

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:
-h
Halt 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.
-r
Reboot after shutdown.
-c
Cancel an already running shutdown.
time
When to shut down (required). You can specify the
time
option in any of the following
ways:
•
Absolute time in the format
hh
:
mm
, in which
hh
is the hour (one or two digits) and
mm
is the minute of the hour (two digits).
•
Number of minutes to wait in the format
+
m
, in which
m
is the number of minutes.
•
now
to immediately shut down; this is equivalent to using
+0
to wait zero minutes.
Refer to the
shutdown
(8) Linux manpage for details. Also refer to the Linux manpage for the
poweroff
command.
NOTE:
On HP rx7620, rx7640, rx8620, and rx8640 servers, you can configure the nPartition
behavior when an OS is shut down and halted (
shutdown -h
or
poweroff
). The two options
are to have hardware power off when the OS is halted or to have the nPartition be made inactive
(all cells are in a boot-is-blocked state).
The normal behavior for Red Hat Enterprise Linux or SuSE Linux Enterprise Server shut down
and halt is for the nPartition to be made inactive.
For details, refer to
“ACPI Softpowerdown Configuration—OS Shutdown Behavior” (page 92)
.
Procedure 4-20 Shutting Down Linux
From the command line for Red Hat Enterprise Linux or SuSE Linux Enterprise Server, issue the
shutdown
command to shut down the OS.
1.
Log in to Linux running on the system you want to shut down.
Log in to the management processor (MP) for the server and use the Console menu to access
the system console. Accessing the console through the MP enables you to maintain console
access to the system after Linux has shut down.
