    Windows 7, Server 2008 R2 & later Installation

    1. Upgrading your ExpressSAS Windows driver
    2. Adding an ExpressSAS adapter to an existing Windows installation
    3. Installing a fresh copy of Windows onto a disk attached to the ExpressSAS adapter

    1. Upgrading your ExpressSAS Windows driver

      To install from the ExpressSAS Installation CD:

      1. Log on to Windows as the system administrator.
      2. Insert the ExpressSAS Installation CD into a CD or DVD drive and the CD will automatically start. If the CD does not start, navigate to the root of the CD and run 'autorun.bat'.
      3. Select "Windows Drivers" from the items on the left side of the screen.
      4. Select the appropriate CPU based operating system from operating system choices.
      5. Select "Install Windows Driver" to launch the driver installer. If you have User Account Control enabled, you will be prompted to grant the installer permission to continue. If you do not have administrator privileges, you will also be prompted for an administrator username and password. Click the 'Continue' button.
      6. Click 'Install' and follow the on-screen instructions to complete the driver installation.

      To install from the ATTO Technology website:

      1. Log on to Windows as the system administrator.
      2. Go to the Downloads section of www.attotech.com and locate the driver download for your product and operating system.
      3. Click on the link to download the file. Internet Explorer users may select 'Run' to automatically run the downloaded self-extracting executable. Otherwise, select a download destination and run the self-extracting executable when the download is complete. If you have User Account Control enabled, you will be prompted to grant the installer permission to continue. If you do not have administrator privileges, you will also be prompted for an administrator username and password. Click the 'Continue' button.
      4. Click 'Unzip' to extract the driver files and launch the driver installer.
      5. Click 'Install' and follow the on-screen instructions to complete the driver installation.

      To install from a directory containing the ExpressSAS driver:

      1. Log on to Windows as the system administrator.
      2. Navigate to the directory containing the ExpressSAS driver and run Setup.exe. If you have User Account Control enabled, you will be prompted to grant the installer permission to continue. If you do not have administrator privileges, you will also be prompted for an administrator username and password. Click the 'Continue' button.
      3. Click 'Install' and follow the on-screen instructions to complete the driver installation.

    2. Adding an ExpressSAS adapter to an existing Windows installation

      Note:
      • It is recommended that you complete this installation procedure before attaching any devices to the adapter.

      1. Perform the installation procedure in (A) to pre-install the ExpressSAS driver. Shutdown Windows when Setup prompts you to do so.
      2. Install your ExpressSAS adapter into an available PCI expansion slot.
      3. Restart Windows. Windows should detect your ExpressSAS adapter and install the driver automatically.
      4. Shutdown the system and setup the final hardware configuration.

        1. If the ExpressSAS adapter is replacing another one in the system, disconnect the cables from the old adapter and remove it from the system. Optionally, you can move the ExpressSAS adapter to the PCI slot that the previous adapter occupied if this slot is more suitable.
        2. Attach the appropriate cables to the ExpressSAS adapter.
        3. Close the computer chassis, turn on the power and restart Windows.

    3. Installing a fresh copy of Windows onto a disk attached to the ExpressSAS adapter

      Note:

      1. Start Windows setup per the instructions provided with Windows. Select a custom installation and proceed to the 'Where do you want to install Windows?' window.
      2. Click 'Load Driver'. Insert media containing the ExpressSAS driver package and click 'OK'.
      3. Windows Setup will search for drivers matching devices in your system. If the ExpressSAS adapter is not listed in the 'Select the driver to be installed.' list, click 'Browse' and locate the driver. Select the ExpressSAS adapter from the list and click 'Next' to install the driver.
      4. You will now be back at the 'Where do you want to install Windows?' window and your devices should be listed. You may remove the ExpressSAS installation media. Configure and select a partition for installing Windows. Click 'Next'.
      5. Finish Windows installation per the instructions provided with Windows.


    Creating ExpressSAS Installation Media

    Use these procedures to transfer the ExpressSAS driver files to alternate media such as a hard drive, floppy disk, or USB flash drive for the installation procedures above.

    To create installation media from the ExpressSAS Installation CD:

    1. Insert the ExpressSAS Installation CD into a CD or DVD drive and the CD will automatically start. If the CD does not start, navigate to the root of the CD and run 'autorun.bat'.
    2. Select "Windows Drivers" from the items on the left side of the screen.
    3. Select the appropriate CPU based operating system from operating system choices.
    4. Select "Create Driver Installation Media" for the desired operating system.
    5. Follow the instructions for creating the installation media.

    To create installation media from an ExpressSAS driver download from the ATTO Technology website:

    1. Go to the Downloads section of www.attotech.com and locate the driver download for your product and operating system.
    2. Click on the link to download the file. Internet Explorer users may select 'Run' to automatically run the downloaded self-extracting executable. Otherwise, select a download destination and run the self-extracting executable when the download is complete.
    3. Uncheck 'When done unzipping open .\Setup.exe'.
    4. Select a different destination folder if desired and click 'Unzip' to extract the driver files.
    5. Navigate to the folder with the ExpressSAS driver.
    6. Run 'makedisk.exe' and follow the instructions for creating the installation media.


  5. Registry Settings

    Note:
    • Modifying your registry incorrectly may result in making your machine unbootable. Please use care in editing the registry.
    • All registry settings are DWORD values.
    • The following settings can be found in the registry under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\esas4hba\Parameters\Device.

    Settings:



  6. Driver Events

    The reporting of driver events is controlled by the EventLogMask registry setting. EventLogMask is the sum of the event type values for the events you would like to see.

    Event Type Value (hexadecimal) Description
    Fatal 0x00000001 Fatal errors, always reported
    SCSI 0x00000004 SCSI command errors
    Protocol 0x00000008 SAS protocol errors
    Login 0x00000010 Device login/logout events
    Resource 0x00000040 Resource usage failures
    Info 0x00000080 Informational messages
    Underflow 0x00000800 Data underflow errors
















    In general, only errors that are output for event type 'Fatal' are significant; all others are mostly for informational or diagnostic purposes. When turning on event logging, be aware that certain events reported as errors are expected. For example, a SCSI Check Condition error will be reported for the first command sent to a device after power on or a reset condition. Also, certain data underrun errors are expected by the software and are normal.

    All events report the adapter number on which the event occurred. The adapter number is simply the order in which Windows initialized the adapter channels and has no relevance to what slot the adapter is in or which channel of the adapter is being reported.
