Prepare to Use Detect

Ensure the following conditions before using Detect:

  • Ensure that SCSI support and tape drive support are enabled on the operating system. Physically connect each tape library to its controller node and device servers. You can do this directly or through a SAN.

  • Ensure the tape device drivers, which are supplied by tape drive manufacturers, are properly installed. Drivers are often available from the manufacturer’s website. Also ensure the following:

    • Drivers are compatible with the operating system of the device server. Consult the documentation provided by your hardware vendor.

    • Tape drivers are capable of writing in variable block size mode.

  • On Windows platforms, ensure you can see the tape drives in Device Manager and the drives are enabled.

  • Ensure DPX client software is installed on controller nodes and device servers. Client software is installed on the master server by default.

  • For controller nodes, ensure the medium changer is not claimed by the operating system or any other software. The medium changer must be available for DPX to claim.

  • Ensure the medium changer device is disabled in the Device Manager. On Windows Server, the medium changer is usually displayed in Device Manager as an Unknown Medium Changer.

To disable the medium changer:

  1. Use either of the following methods to navigate to Device Manager:

    • Click Start > Settings > Control Panel > Administrative Tools > Computer Management > Device Manager.

    • Right-click My Computer, then select Properties > Hardware > Device Manager.

  2. Right-click on the medium changer (usually Unknown Medium Changer). Select Disable.

If you see the message Disabling this device will cause it to stop functioning. Do you want to disable? Select Yes.

Note that disabling the device does not cause the tape library to stop functioning; rather, it removes control of the device by Windows. This enables DPX to claim, detect, and control the device.
