Shutting Down Linux - HP Integrity rx2620 User's & Service Manual

Booting the Operating System
Booting and Shutting Down Linux
From the system console, choose the
shell.
Step 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
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\SuSE\elilo at the EFI Shell
command prompt.
Step 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 has the following
options:
Halts (power off) after shutdown.
-h
Use the PC command at the iLO MP Command menu to manually power on or power off
server hardware, as needed.
Reboots after shutdown.
-r
Cancels an already running shutdown.
-c
When to shut down. (Required.) You can specify time in any of the following ways:
time
• 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.
Step 1. From the command line for Red Hat Enterprise Linux or SuSE Linux Enterprise Server, issue the
shutdown command to shut down the operating system.
Step 2. Log in to Linux running on the server you want to shut down.
Step 3. Issue the shutdown command with the desired command-line options, and include the required
time argument to specify when the operating system shutdown is to occur.
For example, shutdown -r +20 shuts down and reboots the server in twenty minutes.
