***************************************************************************** LSI_SAS3_WIN8.1_2012R2.TXT ***************************************************************************** Installation Guide for the LSI Fusion-MPT (TM) Drivers: LSI_SAS3.SYS (StorPort) V2.50.96 NOTE: The LSI_SAS3 driver built for Windows 8.1 also supports Windows Server 2012R2, which is the server version of Windows 8.1. All references within this document to Windows 8.1 should be interpreted as including Windows Server 2012R2, unless specifically stated otherwise. This file describes the features and use of the LSI Fusion-MPT SAS (Serial Attached SCSI) Gen3 device drivers for the Windows 8.1 and Windows Server 2012R2 operating system environments. It is divided into the following sections: Introduction for Windows 8.1 and Windows Server 2012R2 Features LSI Devices Supported Description Installing the Driver(s) New System Installation DVD-ROM Installation Existing System Installation Performance Tuning for Windows 8.1 Miniport Driver Configuration Options and WDCFG Utility WinPE Installation Troubleshooting ......................................................................... 1.0 Introduction for Windows 8.1 and Windows Server 2012R2 Windows 8.1/2012R2 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 2012R2 is only supported on x64 processors. Refer to the Microsoft Windows 8.1 documentation for details. An I/O manager handles I/O requests in Windows 8.1/2012R2. To address a peripheral, the I/O manager goes through the appropriate drivers. Windows 8.1/2012R2 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_SAS3.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 8.1/2012R2 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_SAS3 miniport driver supports Extended SRB. ......................................................................... 1.1 Features The LSI_SAS3.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_SAS3.SYS - "LSI Fusion-MPT SAS3 Miniport Driver" o LSISAS3004 o LSISAS3008 o LSISAS3108 o LSISAS3116 o LSISAS3208 o LSISAS3308 ......................................................................... 1.3 Description The LSI_SAS3.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 8.1/2012R2 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_SAS3.SYS Driver This procedure installs the LSI_SAS3.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_sas3.inf lsi_sas3.sys lsinodrv.inf wdcfg.exe DriverConfigParam.def lsi_sas3.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 8.1/2012R2. 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_SAS3.SYS driver onto a Windows 8.1/2012R2 system. Use this procedure when installing Windows 8.1/2012R2 onto an unused drive. Windows 8.1/2012R2 automatically adds the driver to the registry and copies the driver to the driver storage area. ............................................................................ 2.1.1 DVD-ROM Installation 1. Start the Windows 8.1/2012R2 installation by booting from the Windows 8.1/2012R2 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 8.1/2012R2. 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_SAS3 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.
