Operating System Boot and Shutdown Shutting Down Linux Shutting Down Linux Use the shutdown command to shut down the Red Hat Linux or the SuSE Linux Enterprise Server operating system. The Red Hat Linux and SuSE Linux Enterprise Server shutdown command includes the following options: -h Halt after shutdown. On nPartition-capable HP Integrity servers, this will either power down server hardware or put the nPartition into a shutdown for reconfig 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.) time can be specified 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 mapage for the poweroff command. NOTE On HP rx7620 servers and rx8620 servers you can configure the nPartition behavior when an OS is shutdown 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 Linux or SuSE Linux Enterprise Server shutdown and halt is for the nPartition be made inactive. For details see "ACPI "Softpowerdown" Configuration-rx7620 and rx8620 OS Shutdown Behavior" on page 174. Linux Shutdown From the command line for Red Hat Linux or SuSE Linux Enterprise Server, issue the shutdown command to shut down the operating system. Step 1. Login to Linux running on the system you want to shut down. Step 2. Issue the shutdown command with the desired command-line options, and include the required time argument to specify when the operating shutdown is to occur. For example, shutdown -r +20 will shutdown and reboot the system starting in twenty minutes. Appendix A 197

Operating System Boot and Shutdown
Shutting Down Linux
Appendix A
197
Shutting Down Linux
Use the
shutdown
command to shut down the Red Hat Linux or the SuSE Linux Enterprise Server operating
system.
The Red Hat Linux and SuSE Linux Enterprise Server
shutdown
command includes the following options:
-h
Halt after shutdown.
On nPartition-capable HP Integrity servers, this will either power down server hardware or
put the nPartition into a shutdown for reconfig 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.)
time
can be specified 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 mapage for the
poweroff
command.
NOTE
On HP rx7620 servers and rx8620 servers you can configure the nPartition behavior when an
OS is shutdown 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 Linux or SuSE Linux Enterprise Server shutdown and halt is
for the nPartition be made inactive.
For details see “ACPI “Softpowerdown” Configuration—rx7620 and rx8620 OS Shutdown
Behavior” on page 174.
Linux Shutdown
From the command line for Red Hat Linux or SuSE Linux Enterprise Server, issue the
shutdown
command to shut down the operating system.
Step 1.
Login to Linux running on the system you want to shut down.
Step 2.
Issue the
shutdown
command with the desired command-line options, and include the required
time
argument to specify when the operating shutdown is to occur.
For example,
shutdown -r +20
will shutdown and reboot the system starting in twenty minutes.
