HP Integrity rx8640, HP 9000 rp8440 Server User Service Guide

3. Issue the shutdown command and the appropriate options to shut down the Windows Server
2003 on the system.
You have the following options when shutting down Windows:
• To shut down Windows and reboot:
shutdown /r
Alternatively, you can select the Start —> Shut Down action and select Restart from the
drop-down menu.
• To shut down Windows and not reboot (either power down server hardware or put an
nPartition into a shutdown for reconfiguration state):
shutdown /s
Alternatively, you can select the Start —> Shut Down action and select Shut down from
the drop-down menu.
• To abort a shutdown (stop a shutdown that has been initiated):
shutdown /a
For example:
shutdown /r /t 60 /c "Shut down in one minute."
This command initiates a Windows system shutdown-and-reboot after a timeout period of 60
seconds. The /c option specifies a message that is broadcast to any other users of the system.
Booting and Shutting Down Linux
This section presents procedures for booting and shutting down the Linux OS on cell-based HP
Integrity servers and a procedure for adding Linux to the boot options list.
• To determine whether the cell local memory (CLM) configuration is appropriate for Red Hat
Enterprise Linux or SuSE Linux Enterprise Server, See “Linux Support for Cell Local Memory”
(page 106).
• To add a Linux entry to the nPartition boot options list, See “Adding Linux to the Boot Options
List” (page 107).
• To boot Red Hat Enterprise Linux, see “Booting Red Hat Enterprise Linux” (page 108).
• To boot SuSE Linux Enterprise Server, see “Booting SuSE Linux Enterprise Server ” (page 109).
• To shut down Linux, see “Shutting Down Linux” (page 110).
Linux Support for Cell Local Memory
On servers based on the HP sx2000 chipset, each cell has a cell local memory (CLM) parameter,
which determines how firmware interleaves memory residing on the cell.
IMPORTANT: Red Hat Enterprise Linux does not support using CLM. Before booting Red Hat
Enterprise Linux on an nPartition, you must ensure that the CLM parameter for each cell in the
nPartition is set to zero (0). Although you might be able to boot Red Hat Enterprise Linux on an
nPartition with CLM configured, any memory configured as cell local is unusable, and such a
configuration is untested and unsupported.
SuSE Linux Enterprise Server supports using CLM. The optimal CLM settings for SuSE Linux Enterprise
Server depend on the applications and workload the OS is running.
To check CLM configuration details from an OS, use Partition Manager or the parstatus
command. For example, the parstatus -V -c# command and parstatus -V -p# command
report the CLM amount requested and CLM amount allocated for the specified cell (-c#, where #
