2. Check whether any users are logged in.
Use the
query user
or
query session
command.
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, refer to
“Linux Support for Cell Local
Memory” (page 114) .
• To add a Linux entry to the nPartition boot options list, refer to “Adding Linux to the Boot
Options List” (page 115) .
• To boot Red Hat Enterprise Linux, refer to “Booting Red Hat Enterprise Linux” (page 116) .
• To boot SuSE Linux Enterprise Server, refer to “Booting SuSE Linux Enterprise Server ”
(page 117) .
• To shut down Linux, refer to “Shutting Down Linux” (page 119) .
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
