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 138). • To add a Linux entry to the nPartition boot options list, refer to "Adding Linux to the Boot Options List" (page 139). • To boot Red Hat Enterprise Linux, refer to "Booting Red Hat Enterprise Linux" (page 140). • To boot SuSE Linux Enterprise Server, refer to "Booting SuSE Linux Enterprise Server " (page 141). • To shut down Linux, refer to "Shutting Down Linux" (page 142). 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 4 Update 4 and later, Red Hat Enterprise Linux 5 and later, and SUSE Enterprise Linux 10 and later, supports using CLM. 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 # is the cell number) or the specified nPartition (-p#, where # is the nPartition number). For details, refer to the HP System Partitions Guide or the Partition Manager Web site (http:// docs.hp.com/en/PARMGR2/). To display CLM configuration details from the EFI Shell on a cell-based HP Integrity server, use the info mem command. If the amount of noninterleaved memory reported is less than 512 MB, then no CLM is configured for any cells in the nPartition (and the indicated amount of noninterleaved memory is used by system firmware). If the info mem command reports more 138 Booting and Shutting Down the Operating System

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

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 138)

•

To add a Linux entry to the nPartition boot options list, refer to

“Adding Linux to the Boot

Options List” (page 139)

•

To boot Red Hat Enterprise Linux, refer to

“Booting Red Hat Enterprise Linux” (page 140)

•

To boot SuSE Linux Enterprise Server, refer to

“Booting SuSE Linux Enterprise Server ”

(page 141)

To shut down Linux, refer to

“Shutting Down Linux” (page 142)

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 4 Update 4 and later, Red Hat Enterprise Linux 5 and

later, and SUSE Enterprise Linux 10 and later, supports using CLM.

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

is the cell number) or the specified nPartition (

-p

, where

is the nPartition number). For

details, refer to the

HP System Partitions Guide

or the Partition Manager Web site (

http://

docs.hp.com/en/P

ARMGR2/

To display CLM configuration details from the EFI Shell on a cell-based HP Integrity server, use

the

info mem

command. If the amount of noninterleaved memory reported is less than 512 MB,

then no CLM is configured for any cells in the nPartition (and the indicated amount of

noninterleaved memory is used by system firmware). If the

info mem

command reports more
