1.0 Introduction for Windows Server 2003  


Windows Server 2003 is an operating system designed to run on Intel 
architecture (32-bit) and Itanium Processor Family (64-bit) processors using
current technology. It provides a graphical user interface environment
incorporating many high-level features. Refer to the Microsoft Windows Server
2003 documentation for details.

An I/O manager handles I/O requests in Windows Server 2003. To address a SCSI
peripheral, the I/O manager goes through the appropriate drivers. Windows
Server 2003 provides class drivers for hard disk, optical, CD-ROM, printer,
and scanner peripherals. Other class drivers, provided by peripheral
manufacturers, may be added to support new devices. Tape device support is
built into the operating system itself and does not require a class driver. 

Microsoft provides the port driver and LSI Logic provides the miniport driver,
which is called SYMMPI.SYS.  This driver completes the path to the LSI Logic 
controller or processor with an optional SCSI or Fibre Channel BIOS.

LSI Logic uses the same filenames for their drivers for different Windows
operating systems.  The driver files are packaged either in separate
subdirectories based on the Windows operating system or on different disks.  
To determine the driver file for Windows Server 2003, note that the filename
ends with .SYS.  For example, this driver is SYMMPI.SYS.

To determine the operating system version, go into Windows Explorer, display
the driver file, right click on the filename, click on Properties, and click
on the Version tab.  Click on the Internal Filename in the lower section.
For Windows Server 2003, the filename appears as filename (Server 2003 32-bit)
for 32-bit systems and filename (Server 2003 64-bit) for 64-bit systems.
The next sections describe these drivers and their installation. 

.........................................................................
1.1 Features

It supports the following devices and their associated host adapters:

o  LSI53C1020 
o  LSI53C1030 
o  LSIFC929X 
o  LSIFC929 
o  LSIFC919X
o  LSIFC919
.........................................................................
1.3 Description

The SYMMPI.SYS driver meets the Microsoft specification for miniport drivers. 
This driver allows connection of parallel SCSI and Fibre Channel devices
including disk drives, CD-ROMs, and tape drives for PCI and PCI-X based
machines. To support a different SCSI or Fibre Channel device type, the
Windows Server 2003 architecture requires that a class driver for that type
of device be present (usually supplied by Microsoft, or possibly by the
peripheral manufacturer). No changes to SYMMPI.SYS are required. The driver
supports only Windows Server 2003 and all subsequent Service Packs. 

A Windows application passes SCSI commands directly to the parallel SCSI or
Fibre Channel Protocol devices by using the SCSI pass-through facility.
This facility allows applications to directly control and access devices by
filling in a data structure and calling into the port or class driver. Refer
to the Microsoft Windows Server 2003 documentation for more details.

............................................................................
2.0 Installing the SYMMPI.SYS Driver  


This procedure installs the SYMMPI.SYS driver onto a new or existing
Windows Server 2003 system. Depending upon the media used to distribute
LSI Logic drivers (web or CD-ROM), you will create a driver diskette.

Copy the files listed in this section to the root directory of a clean
diskette as shown below.  Label this diskette "Windows Server 2003 Driver
Diskette". You will use this diskette during the installation process.

        \txtsetup.oem
        \symmpi.tag
        \32_bit\mpi2k332.cat
        \32_bit\symmpi.inf
        \32_bit\symmpi.sys
        \64_bit\mpi2k364.cat
        \64_bit\symmpi.inf
        \64_bit\symmpi.sys

............................................................................
2.1 New System Installation 

This procedure installs the SYMMPI.SYS driver onto a Windows Server 2003
system. Use this procedure when installing Windows Server 2003 onto an
unused drive. Windows Server 2003 automatically adds the driver to the
registry and copies the driver to the appropriate directory.

The method for installing Windows Server 2003 on a new system involves using
a CD-ROM. Installation using boot floppy diskettes is not supported by
Windows Server 2003.

............................................................................
2.1.1 CD-ROM Installation

1. Start the Windows Server 2003 installation by booting from the Windows
   Server 2003 CD-ROM:

   The system BIOS must support booting from a CD-ROM. BIOS settings may need
   to be changed to allow CD-ROM booting.

2. Press the F6 key to install the SYMMPI.SYS driver when the screen displays
   "Windows Setup".

   This must be done or else the new driver will not be recognized.

Note:  Current Windows Server 2003 drivers can be downloaded from the
       LSI Logic web site at http://www.lsilogic.com/support.  After you
       are connected to this web site, click on "Downloads". Next, click on
       "Download Center". Select the product category, then the appropriate
       product. A bullet in the Drivers section will display all driver
       packages associated with the product selection.

3. Choose S to specify an additional device when the screen displays "Setup
   could not determine the type of one or more mass storage devices...". 

   NOTE: If this screen is not displayed as the first user input, then 
         pressing the F6 key was not seen by the setup program. Reboot the 
         system and try again.

   The system prompts for the manufacturer-supplied hardware support disk.

4. Insert the appropriate driver diskette containing the Windows Server 2003
   driver required to support your LSI Logic adapter(s) and press Enter.
    
Note:  Current Windows Server 2003 drivers can be downloaded from the
       LSI Logic web site at http://www.lsilogic.com/support.  After you
       are connected to this web site, click on "Downloads". Next, click on
       "Download Center". Select the product category, then the appropriate
       product. A bullet in the Drivers section will display all driver
       packages associated with the product selection.

5. The screen will display a list of two drivers to select from:

       "LSI Logic PCI SCSI/FC MPI Driver (Server 2003 32-bit)"
       "LSI Logic PCI SCSI/FC MPI Driver (Server 2003 64-bit)"
   
   Select the driver which matches the processor architecture of the system
   (32-bit or 64-bit). Press Enter to proceed.

   Return to the Windows Server 2003 Setup screen.

6. Press Enter to proceed.

   The message about setup loading files appears.

7. Follow the Microsoft Windows Server 2003 installation procedure
   at this point.

............................................................................
2.2 Existing System Installation

This procedure installs or upgrades the SYMMPI.SYS drivers onto an existing
Windows Server 2003 system.

NOTE: When a LSI Logic SCSI or Fibre Channel adapter is added to an existing
      system installation, the new adapter is automatically detected at the
      next reboot. When the Device Driver Wizard appears at boot, click on the
      Next button and continue at step 8 below.

1. Boot Windows Server 2003 and logon as a user that has Administrator
   privileges.

2. Click on the Start button, then right-click on the My Computer entry in
   the menu.

3. Click on the Properties selection.

4. Click on the Hardware tab, and then the Device Manager button.

5. Click the "+" to the left of the SCSI and RAID controllers line.  Find the
   adapter desired for the driver upgrade and double-click the entry.  Click
   on the Driver tab.

6. Information on the currently installed driver is displayed, and additional
   driver details can be viewed by clicking the "Driver Details" button.

7. Click on the "Update Driver" button to update the existing driver.  The
   Hardware Update Wizard begins.
   
8. Click on the "Install from a list or specific location..." button to select
   it, then click on the Next button.

9. Click on the "Don't search, I will choose the driver to install." button
   to select it, then click on the Next button.

10. Click on the "Have Disk" button and type the path to the driver, or click
    on the Browse button.  Drivers for 32-bit systems will be in the "32_bit"
    directory and drivers for 64-bit systems will be in the 64-bit directory.
    After the path to the driver has been established, click the OK button.

11. Select the driver from the list and click on the Next button.

12. Click on the Next button again to start the driver update.

    In some cases, a message will display saying that this driver has not
    passed logo testing. This message informs you that a nonsigned driver is
    being installed.

    Note: Drivers are digitally signed by the Microsoft Windows Hardware
          Quality Lab (WHQL) on completion of logo testing.  Due to the time
          lag between the general customer release by LSI of Windows drivers
          and the completion of WHQL logo testing, some drivers distributed
          with adapters or downloaded from the www.lsilogic.com web site may
          not be digitally signed.

13. Click STOP Installation to cancel the installation if a nonsigned driver
    is not desired.

      or

    Click Continue Anyway to continue the installation.

    The system will load the driver from the Windows Server 2003 driver
    diskette. A message box may display indicating that the target (existing)
    driver is newer than the source (upgrade) driver.

14. Click No to cancel the driver upgrade at this point.

      or

    Click Yes to continue the installation.

    The system copies the driver to the system disk. For any adapter other
    than the boot adapter, the updated driver will become active immediately.
    For the boot adapter, a message box displays indicating that you must
    reboot your system for the new driver to take effect.

15. Click on the Finish button to complete the driver upgrade.

............................................................................
2.3 Performance Tuning for Windows Server 2003

Windows Server 2003 has registry entries that can be used to tune the
performance of SCSI I/O for certain configurations. The tunable parameters
are large transfer block size support and a guaranteed number of concurrent
I/Os for a particular SCSI bus.

............................................................................
2.3.1 Large Block Size Support 

The SYMMPI.SYS drivers can support up to a 1 Mbyte transfer size (for 32-bit
systems) and 2 Mbyte transfer size (for 64-bit systems) in Windows Server 2003;
however, the default Windows Server 2003 transfer size is 64 Kbytes. To 
enable better performance, the driver installation process adds a registry 
entry to enable a maximum 256 Kbytes transfer size (512 KBytes for 64-bit).
Also, the mpi_256K.reg file can be used to set or re-enable a 256 Kbytes
maximum, but it can be edited to set other desired maximum transfer sizes.
There are two methods to add this registry setting.

1. Locate the mpi_256K.reg data file (supplied with the driver files) using
   Windows Explorer and double-click on the file.
 
   -OR-

2. Type at the command prompt:

   regedit mpi_256K.reg

This inserts an entry in the registry to enable 256 Kbytes block size support
(512 Kbytes for 64-bit). 

Editing the mpi_256K.reg can set any maximum block size between 64 Kbytes and
1 Mbyte (2Mbytes for 64-bit). The formula to calculate the proper value for
MaximumSGList is:

     MaximumSGList = ((Maximum Block Size)/4 Kbytes) +1 (for 32-bit)
     MaximumSGList = ((Maximum Block Size)/8 Kbytes) +1 (for 64-bit)

For 256 Kbytes: 256 Kbytes/4 Kbytes = 64. Add 1 for 65 (decimal) or 
0x41 (hexadecimal). The maximum value allowed for MaximumSGLIst is 255 or 
0xFF. For the particular value of 0xFF, the internal value passed to Windows 
is increased to 0x101, allowing support for a full 1 Mbyte transfer (2 Mbytes
for 64-bit). Be sure to read the information in the mpi_256K.reg data file
before editing it.

The system must be rebooted for the new registry setting to be effective.

To reset the maximum block size to the default of 64 Kbytes, follow the 
instructions above, except use mpidfblk.reg as the data file.

............................................................................
2.3.2 Maximum Number of Concurrent I/Os (Guaranteed)   
  
Windows Server 2003 guarantees a maximum of 32 concurrent I/Os active on a 
particular SCSI bus. However, due to the method of memory allocation, the 
actual limit of concurrent I/Os can vary greatly between various drivers or 
versions of drivers. This can have a huge impact on performance benchmarking 
between different driver versions or adapter vendors. In effect, one adapter 
may actually be able to have 70 or 80 I/Os outstanding, while another adapter 
could only have 32. This can also affect systems with high performance storage 
subsystems, such as disk arrays.

In order to enable better performance, the driver installation process adds a
registry entry to support 128 concurrent I/Os. If a different maximum value is
desired, the file mpi100io.reg can be used to add a registry entry to guarantee
the desired number of concurrent I/Os.

There are two methods to add this registry setting. One is to locate the
mpi100io.reg data file (supplied with the driver files) using Windows Explorer
and double click on the file. The other method is to type at the command
prompt:

     regedit mpi100io.reg

This inserts an entry in the registry to guarantee a maximum of 100 
concurrent I/Os per adapter.

If a maximum other than 100 is desired, the mpi100io.reg can be edited;
however, setting this value to a high number uses increasing amounts of
non-paged pool memory, a critical Windows resource. High values for this
setting can degrade system performance. Be sure to read the information
in the mpi100io.reg data file before editing it.

The system must be rebooted for the new registry setting to be effective.

To reset the guaranteed number of concurrent I/Os to the default of 32, 
follow the instructions above, except use mpidefio.reg as the data file.  

............................................................................
2.3.3 Miniport Driver Configuration Options

The SYMMPI driver is configured by default to provide optimum performance 
in most standard systems. Some non-standard systems may require fine 
tuning to obtain peak system memory utilization and performance. After 
installation, if less than advertised functionality and performance is 
observed on any platform, please contact LSI Logic support. Go to the LSI Logic
Technical Support Home Page, which is located at:

http://www.lsilogic.com/support/index.html

and call the listed number for assistance.

LSI Logic can provide additional registry settings if required, to customize 
the driver for specific systems and applications.  

............................................................................
3.0 Troubleshooting 

The SYMMPI.SYS driver will log error messages to the system error log. For
these errors, the system errorlog EventID will be 11, and the specific error
code values will be displayed at offset 0x10. Data should be displayed in
words.
