***************************************************************************** WINXP.TXT ***************************************************************************** Installation Guide for the LSI Fusion-MPT (TM) Driver: SYMMPI.SYS V1.28.03 This file describes the features and use of the LSI Fusion-MPT SCSI/Fibre Channel/SAS (Serial Attached SCSI) device drivers for the Windows XP operating system environment. It is divided into the following sections: Introduction for Windows XP Features LSI Devices Supported Description Installing the Driver(s) New System Installation CD-ROM Installation Existing System Installation Performance Tuning for Windows XP Large Block Size Support Maximum Number of Concurrent I/Os Miniport Driver Configuration Options Hibernation Support Troubleshooting ......................................................................... 1.0 Introduction for Windows XP Windows XP is an operating system designed to run on Intel-architecture (x86, 32-bit) and Itanium Processor Family (IA64) processors using current technology. It provides a graphical user interface environment incorporating many high-level features. Refer to the Microsoft Windows XP documentation for details. An I/O manager handles I/O requests in Windows XP. To address a SCSI peripheral, the I/O manager goes through the appropriate drivers. Windows XP 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 Corporation provides the miniport driver, which is called SYMMPI.SYS. This driver completes the path to the LSI controller or processor with an optional SCSI, Fibre Channel, or SAS BIOS. LSI uses the same filenames for their drivers for different Windows operating systems. The driver files are packaged in separate folders or zip files based on the Windows operating system version/system platform combination, or on different disks. To determine the driver file for Windows XP, 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 XP, the filename appears as filename (XP 32-bit) for 32-bit (x86) systems and filename (XP IA64) for IA64 systems. The next sections describe these drivers and their installation. ......................................................................... 1.1 Features The SYMMPI.SYS miniport driver supports these features: o Supports 320 Mbytes/s parallel SCSI transfers (for LSI53C1020 and LSI53C1030) o Supports Integrated Mirroring (TM) technology (for LSI53C1020 and LSI53C1030) o Supports PCI, PCI-X, and PCI-Express bus protocols o Supports 1GB, 2GB and 4GB Fibre Channel transfers (for LSIFC949X, LSIFC949E, LSIFC929X, LSIFC919X, LSIFC929 and LSIFC919) o Supports End-to-End Data Protection (EEDP) for LSIFC949X, LSIFC949E o Supports 1.5GB and 3GB SAS expanders/devices and SATA devices (for LSISAS1064, LSISAS1068, LSISAS1064E, LSISAS1068E, LSISAS1078) o Supports LSI MPT common software interface o Supports multiple host adapters o Supports multiple Logical Unit Numbers (LUNs) o Supports Scatter-Gather o Supports SCSI pass-through functionality o Supports disk array configurations with no LUN 0 o Supports disk array configurations with non-contiguous LUNs o Auto request sense o Maximum block size support: 1 Mbyte (32-bit), 2 Mbyte (64-bit) o Supports Microsoft WMI HBA API for Fibre Channel devices ......................................................................... 1.2 LSI Devices Supported The SYMMPI.SYS driver is named "LSI PCI Fusion-MPT Miniport Driver." It supports the following devices and their associated host adapters: o LSI53C1020 / LSI53C1020A o LSI53C1030 o LSIFC919 o LSIFC919X o LSIFC929 o LSIFC929X o LSIFC949X o lsiFC949E o LSISAS1064 o LSISAS1068 o LSISAS1064E o LSISAS1068E o LSISAS1078 ......................................................................... 1.3 Description The SYMMPI.SYS driver meets the Microsoft specification for miniport drivers. This driver allows connection of parallel SCSI, Fibre Channel, and SAS devices including disk drives, CD-ROMs, and tape drives for PCI and PCI-X based machines. To support a different SCSI, Fibre Channel, or SAS device type, the Windows XP 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 XP and all subsequent Service Packs. A Windows application passes SCSI commands directly to the parallel SCSI, Fibre Channel, or SAS 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 XP documentation for more details. ............................................................................ 2.0 Installing the SYMMPI.SYS Driver This procedure installs the SYMMPI.SYS driver onto a new or existing Windows XP system. Depending upon the media used to distribute LSI drivers (web or CD-ROM), you will create a driver diskette. Copy the files listed in this section from the driver install package for the appropriate platform (x86 or IA64) to the root directory of a clean diskette as shown below. Label this diskette "Windows XP Driver Diskette". You will use this diskette during the installation process. \txtsetup.oem \symmpi.tag \lsipseud.inf \symmpi.inf \symmpi.sys \mpixp32.cat (for x86) or \mpixp64.cat (for IA64) For a driver upgrade the driver files can also be copied onto a hard drive, CD or DVD, or a USB flash drive. ............................................................................ 2.1 New System Installation This procedure installs the SYMMPI.SYS driver onto a Windows XP system. Use this procedure when installing Windows XP onto an unused drive. Windows XP automatically adds the driver to the registry and copies the driver to the appropriate directory. The method for installing Windows XP on a new system involves using a CD-ROM. Installation using boot floppy diskettes is not supported by Windows XP. ............................................................................ 2.1.1 CD-ROM Installation 1. Start the Windows XP installation by booting from the Windows XP 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: Be sure to press the F6 key as any driver loaded later in the installation process is not recognized by Windows XP Setup. If F6 is not pressed, all devices controlled by the drivers are not available during Windows XP setup. 3. Choose S to specify an additional device when the screen displays "Setup was unable to load support for the mass storage device you specified...". 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 XP driver required to support your LSI adapter(s) and press Enter. Note: Current Windows XP drivers can be downloaded from the LSI web site at: http://www.lsi.com/cm/DownloadSearch.do After you are connected to this web site, select the product category, family, and the appropriate product. Select the desired Windows XP driver to begin the download. 5. The screen will display one entry to select, depending on the system platform (x86 or IA64): "LSI PCI Fusion-MPT Driver (XP 32-bit)" or "LSI PCI Fusion-MPT Driver (XP IA64)" Verify the driver displayed matches the processor architecture of the system (32-bit or IA64). Press Enter to proceed. Return to the Windows XP Setup screen. 6. Press Enter to proceed. The message about setup loading files appears. 7. Follow the Microsoft Windows XP installation procedure at this point. ............................................................................ 2.2 Existing System Installation This procedure installs or upgrades the SYMMPI.SYS drivers onto an existing Windows XP system. NOTE: When a LSI SCSI, Fibre Channel, or SAS 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 XP 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. Select the location for the driver package which matches the processor architecture of the system (x86 or IA64). 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.lsi.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 XP 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 XP Windows XP 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 in Windows XP; however, the default Windows XP transfer size is 64 Kbytes. To enable better performance, the driver installation process adds a registry entry to enable the maximum 1 Mbyte transfer size. Also, the mpi_256K.reg file can be used to set or 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. Editing the mpi_256K.reg can set any maximum block size between 64 Kbytes and 1 Mbyte. The formula to calculate the proper value for MaximumSGList is: MaximumSGList = ((Maximum Block Size)/4 Kbytes) +1 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. 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 operating system default of 64 Kbytes, follow the instructions above, except use mpidfblk.reg as the data file. NOTE: For IA64 systems, the OS page size is 8 Kbytes instead of 4 Kbytes. Therefore, the maximum transfer size is 2 Mbytes, the default driver installation enables support for 512 Kbytes transfer size, and the formula becomes: MaximumSGList = ((Maximum Block Size)/8 Kbytes) +1 ............................................................................ 2.3.2 Maximum Number of Concurrent I/Os (Guaranteed) Windows XP 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 255 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 NT 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 operating system 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. ............................................................................ 3.0 Hibernation Support The LSI Fusion-MPT storage adapters and the SYMMPI.SYS driver are high performance storage solutions. This performance level requires a level of resources above that of typical storage adapters. This resource level is supported adequately by Windows XP during normal operations. However, due to limitations imposed by Windows XP, when attempting to Hibernate the system may fail to Hibernate and display the following error message: Windows - System Error Insufficient system resources exist to complete the API. To allow Windows XP to Hibernate successfully, all critical Windows Update patches should be applied to the system. These patches can be downloaded at: http://windowsupdate.microsoft.com ............................................................................ 4.0 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.Download Driver Pack
