HP Integrity rx8640, HP 9000 rp8440 Server User Service Guide

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.

See shutdown(8) Linux manpage for details. Also see 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, see “ACPI Softpowerdown Configuration—OS Shutdown Behavior” (page 84).

Procedure 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.

the system console. Accessing the console through the MP enables you to maintain console

access to the system after Linux has shut down.

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 shut down and reboot the system starting in 20 minutes.
