HP StorageWorks DAT USB Tape Drives - Installing the Drivers

Installing on Windows

Two drivers are required in order to use HP StorageWorks DAT USB tape drives.

  • hpdat :This is the tape driver that works with all HP DAT products. It is regularly updated and is available on the HP StorageWorks CD-ROM or on the HP Support web site.
  • hp_usbstor : This is a USB Storage device used by hpdat and it replaces the Microsoft usbstor driver for HP USB tape drives. The HP StorageWorks USB DAT drives will work with the Microsoft usbstor driver, however, HP strongly recommends the use of the hp_usbstor driver as it offers improved functionality.
NOTE: We strongly recommend that you use the installer package on the HP StorageWorks CD-ROM to install the two drivers BEFORE you connect the tape drive.

Updates to the drivers may be provided from time to time on the HP support web site ( www.hp.com/support ). We recommend that these are installed after using the installer on the CD-ROM.

Recommended install process, before connecting the tape drive

  1. Insert the StorageWorks CD
  2. Select the install drivers link.
  3. Run the automated installer and follow the process to load the two drivers onto the system.

When you attach or install the tape drive connecting to a USB 2.0 port, as described in this guide, and switch it on, the tape drive will be detected automatically and the correct drivers used.

Alternative install process, after connecting the tape drive

If drivers have not already been installed, the Windows Found New Hardware wizard may run when you power on the server and tape drive. Either follow the on-screen instructions to search for the required drivers on the CD-ROM or:

  1. Cancel the wizard and insert the HP StorageWorks CD-ROM.
  2. Select the install drivers link on the CD-ROM.
  3. Run the automated installer and follow the process to load the two drivers onto the system.
  4. On completion of the installation the tape drive will be ready to use.

Ensure the hp_usbstor driver is being used (Windows)

The HP StorageWorks USB DAT drive will work with the Microsoft usbstor driver, however, HP strongly recommends that you use the hp_usbstor driver for improved performance.

To check the driver being used:

  1. Go to Device Manager and select Devices by connection from the View menu.
  2. Expand Universal Serial Bus controllers and locate the tape drive.
  3. If the tape drive is connected to the HP USB Mass Storage Device, it is configured correctly.

Installing on Linux

The Linux operating system also requires two drivers. These drivers are included with the operating system and should be loaded automatically.

Check drivers (Linux)

Use the following procedure to check that both drivers are present:
  1. usb_storage driver
    • At the command prompt type:

      lsmod | grep usb_storage

    • The output of this command should contain a line similar to:

      usb_storage 61193 0

    • If this line is not present, type:

      modprobe usb_storage

      at the command line to load the usb-storage driver.

  2. st tape driver
    • At the command prompt type:

      lsmod | grep st

    • The output of this command should contain a line similar to:

      st 35933 0

    • If this line is not present, type:

      modprobe st

      at the command line to load the st driver.
