***************************************************************************** LSI_SAS2_WIN7_2008R2.TXT ***************************************************************************** Installation Guide for the LSI Fusion-MPT (TM) Drivers: LSI_SAS2.SYS (StorPort) V2.00.76.00 NOTE: The LSI_SAS2 driver built for Windows 7 also supports Windows Server 2008-R2, which is the server version of Windows 7. All references within this document to Windows 7 should be interpreted as including Windows Server 2008-R2, unless specifically stated otherwise. This file describes the features and use of the LSI Fusion-MPT SAS (Serial Attached SCSI) Gen 2 device drivers for the Windows 7 and Server 2008-R2 operating system environment. It is divided into the following sections: Introduction for Windows 7 and Server 2008-R2 Features LSI Devices Supported Description Installing the Driver(s) New System Installation DVD-ROM Installation Existing System Installation Performance Tuning for Windows Server 2008 Miniport Driver Configuration Options and WDCFG Utility WinPE Installation Troubleshooting ......................................................................... 1.0 Introduction for Windows 7 and Server 2008-R2 Windows 7 is the client release of the operating system. Windows Server 2008 R2 is the server version of this release. In all of the information below, this release will be referred to as Windows 7, but that will also include the Server 2008-R2 releases as well. Windows 7 is an operating system designed to run on Intel architecture (x86, 32-bit), Itanium Processor Family (IA64), 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 7 is supported only on 32-bit and x64 processors, and Server 2008 R2 is supported only on x64 and IA64 processors. Refer to the Microsoft Windows 7 / Server 2008 R2 documentation for details. An I/O manager handles I/O requests in Windows 7. To address a peripheral, the I/O manager goes through the appropriate drivers. Windows 7 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. ......................................................................... 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) ......................................................................... 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 7 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 7 / Server 2008 R2 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 7 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 7 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 lsi_sas2.cat 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 7 / Server 2008 R2. 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 7 system. Use this procedure when installing Windows 7 onto an unused drive. Windows 7 automatically adds the driver to the registry and copies the driver to the driver storage area. Note: Windows 7 contains a bundled LSI_SAS2 driver. This drivers will support a fresh installation of Windows 7. 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 7 installation by booting from the Windows 7 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 7. 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
