HP Integrity rx7620 Server - User Service Guide, Sixth Edition

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.
For details, see the shutdown (8) Linux manpage. See also the Linux manpage for the poweroff
command.
NOTE: 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 - OS Shutdown Behavior” (page 206).
Procedure D-10 Linux Shutdown

command to shut down the operating system.
1. Login to Linux running on the system you want to 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 shutdown and reboot the system starting in twenty
