***************************************************************************** LSI_SAS2_WIN8.TXT ***************************************************************************** Installation Guide for the LSI Fusion-MPT (TM) Drivers: LSI_SAS2.SYS (StorPort) V2.00.60.02 This file describes the features and use of the LSI Fusion-MPT SAS (Serial Attached SCSI) Gen 2 device drivers for the Windows 8 operating system environment. It is divided into the following sections: Introduction for Windows 8 Features LSI Devices Supported Description Installing the Driver(s) New System Installation DVD-ROM Installation Existing System Installation Performance Tuning for Windows 8 Miniport Driver Configuration Options and WDCFG Utility WinPE Installation Troubleshooting ......................................................................... 1.0 Introduction for Windows 8 Windows 8 is an operating system designed to run on Intel architecture (x86, 32-bit) and Extended-64 (x64, AMD64/EM64T) processors using current technology. It provides a graphical user interface environment incorporating many high-level features. Note that Windows Server 8 is only supported on x64 processors. Refer to the Microsoft Windows 8 documentation for details. An I/O manager handles I/O requests in Windows 8. To address a peripheral, the I/O manager goes through the appropriate drivers. Windows 8 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 drivers, which is called LSI_SAS2.SYS. This driver completes the path to the LSI controller or processor with an optional SAS BIOS. This miniport driver uses the Microsoft StorPort port driver (rather than the Microsoft ScsiPort driver in earlier versions of Windows). The StorPort driver has architectural enhancements that provide performance improvements on large server systems with many storage adapters. This miniport driver is designed to take advantage of these enhancements for improved performance. A new Storport driver feature for Windows 8 is Extended SRB (Storage Request Block). This new type of request is very extensible and allows for better performance and additional new features in future versions of Windows. The LSI_SAS2 miniport driver supports Extended SRB. ......................................................................... 1.1 Features The LSI_SAS2.SYS miniport driver supports these features: o Supports End-to-End Data Protection (EEDP) o Supports 1.5Gb, 3Gb, and 6Gb SAS expanders/devices and SATA devices o Supports PCI-Express bus protocols o Supports MSI/MSI-X 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 Supports Storport Interrupt Redirection performance enhancements o Auto request sense o Maximum block size support: 1 Mbyte (32-bit), 2 Mbyte (64-bit) o Supports Storport Extended SRB (Storage Request Block) ......................................................................... 1.2 LSI Devices Supported The miniport driver names are listed below, along with their supported devices and associated host adapters: LSI_SAS2.SYS - "LSI Fusion-MPT SAS2 Miniport Driver" o LSISAS2004 o LSISAS2008 o LSISAS2108 o LSISAS2116 o LSISAS2208 o LSISAS2308 ......................................................................... 1.3 Description The LSI_SAS2.SYS driver meets the Microsoft specification for miniport drivers. These drivers allow connection of SAS devices including disk drives, CD/DVD-ROMs, and tape drives for PCI-Express based machines. To support a different SAS device type, the Windows 8 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 the LSI drivers are required. The driver supports only Windows 8 and all subsequent Service Packs. A Windows application passes SCSI commands directly to the 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 8 documentation for more details. ............................................................................ 2.0 Installing the LSI_SAS2.SYS Driver This procedure installs the LSI_SAS2.SYS driver onto a new or existing Windows 8 system. Depending upon the media used to distribute LSI drivers (web or CD-ROM) and the type of adapter, you will create a driver install package on some type of accessible media. This can be a diskette, CD or DVD, or USB flash drive. The driver install package can also be placed on a hard disk for driver upgrades only. Copy the files listed in this section to a folder on the desired media as shown below. You will use this driver package during the installation process. lsi_sas2.inf lsi_sas2.sys lsinodrv.inf wdcfg.exe DriverConfigParam.def svlhx86.cat (for x86) or svlhia64.cat (for IA64) or svlhx64.cat (for x64) Note: Windows drivers must be either Release signed (by LSI) or WHQL logo signed (by Microsoft Windows Hardware Quality Labs) to be installed on Windows 8. Any modifications to any of the above files will invalidate the digital signature of the package and the OS will not install the driver. ............................................................................ 2.1 New System Installation This procedure installs the LSI_SAS2.SYS driver onto a Windows 8 system. Use this procedure when installing Windows 8 onto an unused drive. Windows 8 automatically adds the driver to the registry and copies the driver to the driver storage area. Note: Windows 8 contains a bundled LSI_SAS2 driver. This drivers will support a fresh installation of Windows 8. If a newer driver is to be installed, the fresh installation can be done with the bundled driver and the driver can be upgraded after installation has completed as described in Section 2.2. Or, the newer driver can be used for fresh installation as described in the following section. ............................................................................ 2.1.1 DVD-ROM Installation 1. Start the Windows 8 installation by booting from the Windows 8 DVD-ROM: The system BIOS must support booting from a DVD-ROM. BIOS settings may need to be changed to allow DVD-ROM booting. 2. Proceed with the installation of Windows 8. When the screen displays "Where do you want to install Windows?", click on the Load Driver icon. 3. Be sure the media with the LSI_SAS2 driver install package for the system processor architecture is inserted in the system. Click the Browse button, browse to the location of the driver package, then click OK. Note: Current Windows 8 drivers can be downloaded from the LSI Corporation 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 8 driver to begin the download. 4. The LSI adapter driver name will be displayed, click Next. Note: When using a Release Signed driver, a Windows Secutiry dialog box may appear, indicating that the publisher of this software is LSI Corporation. Click the Install button to continue installation of the driver. A second Windows Security dialog box may appear, indicating that a LSI system device is being installed. This is to install drivers for LSI storage enclosure processors. Click the Install button to continue installation of the driver. 5. Follow the Microsoft Windows 8 installation procedure at this point. ............................................................................ 2.2 Existing System Installation This procedure installs or upgrades the LSI_SAS2.SYS driver onto an existing Windows 8 system. NOTE: When a LSI SAS Gen2 adapter is added to an existing system installation, the new adapter is automatically detected at the next reboot. When the Update Driver Software Wizard appears at boot, continue at step 8 below. 1. Boot Windows 8 and logon as a user that has Administrator privileges. 2. Right-click on a blank area of the Task Bar, then click Task Manager. 3. Click File, then Run New Task. 4. In the Open: box, type devmgmt.msc, then click OK. The Device Manager window will open. 5. Click the arrow to the left of the Storage 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 Update Driver Software wizard begins. 8. Click on the "Browse my computer for driver software" selection. 9. Click on the "Let me pick..." selection at the bottom of the window. 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 x64). 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. Note: When using a Release Signed driver, a Windows Secutiry dialog box may appear, indicating that the publisher of this software is LSI Corporation. Click the Install button to continue installation of the driver. A second Windows Security dialog box may appear, indicating that a LSI system device is being installed. This is to install drivers for LSI storage enclosure processors. Click the Install button to continue installation of the driver. 12. The system will load the driver from the Windows 8 driver package media. 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 bdisplays indicating that you must reboot your system for the new driver to take effect. 15. Click on the Close button to complete the driver upgrade. ............................................................................ 2.3 Performance Tuning for Windows 8 Windows 8 has registry entries that can be used to tune the performance of SCSI I/O for certain configurations. The registry settings of NumberOfRequests and MaximumSGList are not used by StorPort and will have no effect on the LSI_SAS2.SYS driver. ............................................................................ 2.3.1 Miniport Driver Configuration Options The LSI_SAS2.SYS driver is configured by default to provide optimum performance in most standard systems. However, it is possible to fine-tune certain driver parameters using a utility provided on the OS installation disk, the Windows Driver Configuration Utility (WDCFG). The WDCFG utility is fully installed automatically as part of the driver installation. To use the utility, first launch a Command Prompt window. In the Command Prompt window, enter the "wdcfg -?" command to display full usage information. The usage information explains how to query and set parameters, and how to use the utility to display a list of driver configuration parameters which can be controlled using the utility (including full explanations of each). Note that parameter changes are only activated within the driver following a driver initialization. This may be done by restarting the machine, or by using Device Manager to disable and re-enable the driver (Take care not to do this to a driver servicing the boot volume). ............................................................................ 2.4 WinPE Installation WinPE is provided to system OEM's to create a Pre-install Environment image. To use the LSI_SAS2.SYS driver with the Windows 8 based WinPE, perform the steps listed below. 1. Create an lsi_sas2 folder in the winpe_image directory under i386\system32. For example: mkdir winpe_image\i386\system32\lsi_sas2 2. Copy the lsi_sas2 driver package to the winpe_image\i386\system32\lsi_sas2 folder. 3. Edit the winpe_image\i386\System32\Winpeoem.sif to remove the semicolons from the [OemDriverParams] section and add the name of the lsi_sas2 directory to the OemDriverDirs entry. For example: [OemDriverParams] OemDriverRoot = "" OemDriverDirs = lsi_sas2 4. You can then use oscdimg to create a bootable .iso image, or follow the WinPE User's Guide to create a bootable USB flash device. ............................................................................ 3.0 Troubleshooting The LSI_SAS2.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
