This section has procedures for booting and shutting down Microsoft Windows on cell-based HP Integrity servers and a procedure for adding Windows to the boot options list.

Microsoft Windows Support for Cell Local Memory

On servers based on the HP sx1000 chipset or HP sx2000 chipset, each cell has a cell local memory (CLM) parameter, which determines how firmware interleaves memory residing on the cell.

NOTE: Microsoft Windows supports using CLM on cell-based HP Integrity servers. For best performance in an nPartition running Windows, HP recommends that you configure the CLM parameter to 100% for each cell in the nPartition.

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).

To check 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 than 512 MB of noninterleaved memory then use use Partition Manager or the parstatus command to confirm the CLM configuration details.

To set the CLM configuration, use Partition Manager or the parmodify command.

Adding Microsoft Windows to the Boot Options List

To add a Microsoft Windows entry to the system boot options list you must do so from EFI by using the \MSUtil\nvrboot.efi utility to import boot options from the EFI\Microsoft\WINNT50\Boot00... file on the device from which Windows is loaded.

NOTE: On HP Integrity servers, the operating system installer automatically adds an entry to the boot options list.

Procedure 5-19 Adding a Microsoft Windows Boot Option

This procedure adds the Microsoft Windows item to the boot options list.

  1. Access the EFI Shell environment.

    Login to the management processor and enter CO to access the system console.

    When accessing the console, confirm that you are at the EFI Boot Manager menu (the main EFI menu). If at another EFI menu, select the Exit option from the sub-menus until you return to the screen with the EFI Boot Manager heading.

    From the EFI Boot Manager menu, select the EFI Shell menu option to access the EFI Shell environment.

  2. Access the EFI System Partition (fsX: where X is the file system number) for the device from which you want to boot Microsoft Windows.

    For example, enter fs2: to access the EFI System Partition for the bootable file system number 2. The EFI Shell prompt changes to reflect the file system currently accessed.

    The full path for the Microsoft Windows loader is \efi\microsoft\winnt50\ia64ldr.efi and it should be on the device you are accessing. (However, you must only initiate this loader from the EFI Boot Menu and not from the EFI Shell.)

  3. List the contents of the \EFI\Microsoft\WINNT50 directory to identify the name of the Windows boot option file (Boot00nn) that you want to import into the system boot options list.

    fs0:\> ls EFI\Microsoft\WINNT50 Directory of: fs0:\EFI\Microsoft\WINNT50 09/18/03 11:58a <DIR> 1,024 . 09/18/03 11:58a <DIR> 1,024 .. 12/18/03 08:16a 354 Boot0001 1 File(s) 354 bytes 2 Dir(s) fs0:\>
  4. At the EFI Shell environment, issue the \MSUtil\nvrboot.efi command to launch the Microsoft Windows boot options utility.

    fs0:\> msutil\nvrboot NVRBOOT: OS Boot Options Maintenance Tool [Version 5.2.3683] 1. SUSE SLES 9 2. HP-UX Primary Boot: 0/0/1/0/0.2.0 * 3. Windows Server 2003, Datacenter 4. EFI Shell [Built-in] * = Windows OS boot option (D)isplay (M)odify (C)opy E(x)port (I)mport (E)rase (P)ush (H)elp (Q)uit Select>
  5. Use the Import command to import the Windows boot option file.

    Select> i Enter IMPORT file path: \EFI\Microsoft\WINNT50\Boot0001 Imported Boot Options from file: \EFI\Microsoft\WINNT50\Boot0001 Press enter to continue
  6. Type Q to quit the NVRBOOT utility, and exit the console and management processor interfaces if you are finished using them.

    To exit the EFI environment press ^B (Control-B); this exits the system console and returns to the management processor Main Menu. To exit the management processor, type X at the Main Menu.

Booting Microsoft Windows

You can boot the Windows Server 2003 OS on an HP Integrity server by using the EFI Boot Manager to choose the appropriate Windows item from the boot options list.

Refer to “Shutting Down Microsoft Windows” for details on shutting down the Windows OS.

CAUTION:

ACPI Configuration for Windows Must Be windows. On cell-based HP Integrity servers, to boot the Windows OS an nPartition must have its ACPI configuration value set to windows.

At the EFI Shell, enter the acpiconfig command with no arguments to list the current ACPI configuration. If the acpiconfig value is not set to windows, then Windows cannot boot; in this situation you must reconfigure acpiconfig or booting will be interrupted with a panic when launching Windows.

To set the ACPI configuration for Windows: At the EFI Shell enter the acpiconfig windows command, and then enter the reset command for the nPartition to reboot with the proper (windows) configuration for Windows.

NOTE:

Microsoft Windows Booting on HP Integrity Servers. The recommended method for booting Windows is to use the EFI Boot Manager menu to choose a Windows entry from the boot options list. Using the ia64ldr.efi Windows loader from the EFI Shell is not recommended.

Procedure 5-20 Windows Booting

From the EFI Boot Manager menu, choose an item from the boot options list to boot Windows using that boot option. The EFI Boot Manager is available only on HP Integrity servers.

Refer to “ACPI Configuration for Windows Must Be windows” for required configuration details.

  1. Access the EFI Boot Manager menu for the system on which you want to boot Windows.

    Log in to the management processor and enter CO to access the Console list. Choose the nPartition console.

    When accessing the console, confirm that you are at the EFI Boot Manager menu (the main EFI menu). If you are at another EFI menu, choose the Exit option from the submenus until you return to the screen with the EFI Boot Manager heading.

  2. At the EFI Boot Manager menu, choose an item from the boot options list.

    Each item in the boot options list references a specific boot device and provides a specific set of boot options or arguments to be used when booting the device.

  3. Press Enter to initiate booting using the chosen boot option.

  4. When Windows begins loading, wait for the Special Administration Console (SAC) to become available.

    The SAC interface provides a text-based administration tool that is available from the nPartition console. For details refer to the SAC online help (type ? at the SAC> prompt).

    Loading.: Windows Server 2003, Datacenter Starting: Windows Server 2003, Datacenter Starting Windows... ******************************************************************************** Computer is booting, SAC started and initialized. Use the "ch -?" command for information about using channels. Use the "?" command for general help. SAC>
  5. Exit the console and management processor interfaces if you are finished using them.

    To exit the console environment, press ^B (Control-B); this exits the console and returns to the management processor Main menu. To exit the management processor, type X at the Main menu.

Shutting Down Microsoft Windows

You can shut down the Windows OS on HP Integrity servers using the Start menu or the shutdown command.

CAUTION: Do not shut down Windows using Special Administration Console (SAC) restart or shutdown commands under normal circumstances.

Issuing restart or shutdown at the SAC> prompt causes the system to restart or shut down immediately and can result in the loss of data.

Instead use the Windows Start menu or the shutdown command to shut down gracefully.

To shut down Windows use either of the following methods.

  • Choose Shut Down from the Start menu and choose either Restart or Shut down from the pull-down menu.

    The Restart menu item shuts down and restarts the system. The Shut down menu item shuts down the system.

    You can use this method when using a graphical interface to the system.

  • Issue the shutdown command from the Windows command line.

    Refer to the procedure “Windows Shutdown from the Command Line” for details.

    You can issue this command from a command prompt through the Special Administration Console (SAC) or from any other command line.

    The Windows shutdown command includes the following options:

    /s

    Shut down the system. This is the equivalent of Start->Shut Down->Shut down.

    /r

    Shut down and restart the system. This is the equivalent of Start->Shut Down->Restart.

    /a

    Abort a system shutdown.

    /t xxx

    Set the timeout period before shutdown to xxx seconds. The timeout period can range from 0-600, with a default of 30.

    Refer to the help shutdown Windows command for details.

NOTE: On HP rx7620, rx7640, rx8620, and rx8640 servers, performing a shutdown using shutdown /s (or the equivalent Start->Shut Down->Shut down) powers off the server cabinet or powers off the cells and I/O chassis assigned to the nPartition. On these servers you can customize this behavior. For details refer to “ACPI Softpowerdown Configuration—OS Shutdown Behavior”.

On HP Integrity Superdome servers, the Windows shutdown /s command shuts down the system and keeps all cells at BIB (the boot-is-blocked, inactive state).

Procedure 5-21 Windows Shutdown from the Command Line

From the Windows command line, issue the shutdown command to shut down the OS.

  1. Log in to Windows running on the system that you want to shut down.

    For example, access the system console and use the Windows SAC interface to start a command prompt, from which you can issue Windows commands to shut down the the system.

  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 choose the Start->Shut Down-> action and choose Restart from the pull-down menu.

    • To shut down Windows and not reboot (either power down server hardware or put an nPartition into a shutdown for reconfig state):

      shutdown /s

      Alternatively, you can choose the Start->Shut Down-> action and choose Shut down from the pull-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.
