1. Connect the Tape Library

  1. Physically connect the tape library to the SAN.

  2. On the tape library, ensure the device drivers, which are supplied by tape drive manufacturers, are properly installed, enabling SCSI support and tape drive support.

    • On Windows platforms, ensure you see the tape drives from the operating system in Device Manager, and that these drives are enabled.

    • On Linux platforms, verify that the operating system can see the devices by issuing the command cat /proc/scsi/scsi which displays a list of visible devices. Note that most media changers and tape device drivers are available through the default install, though IBM devices may require installation of an additional driver.

  3. If the controller node runs on a Windows platform, it is usually necessary to disable the media changer, leaving it available for Catalogic DPX to claim. Go to Device Manager and ensure media changer is disabled. However, some manufacturers have modified their device drivers with the necessary pass-through interfaces, thereby requiring that the media changer be enabled in Device Manager. The recommended procedure for a new installation is:

    • Disable the driver in Device Manager. Then test the media changer by running detect -i. If detect -i returns a 0 or 3, the media changer drive works successfully.

    Note. On the controller node, run detect -i from a Command Prompt window or terminal window. The detect utility is found in the bin\JB subfolder under the main Catalogic DPX installation folder.

    • If detect -i returns a return code other than 0 or 3, attempt to enable the generic media changer in Device Manager. Test the media changer in the same way, by running detect -i. If detect -i returns a 0 or 3, the media changer drive works successfully.

    • If detect -i still does not return 0 or 3, load the vendor supplied driver and enable it in Device Manager. Test the media changer in the same way, by running detect -i. If detect -i returns a 0 or 3, the media changer drive works successfully.

  4. If none of the above methods succeeds:

    • Check that the HBA adapter accessing the media changer has the latest manufacturer firmware updates.

    • Check that the host operating system has the vendor's most current HBA adapter drivers installed.

    • On Windows 2003 nodes with HBA connections, check for and install Storport patches.

  5. If none of these methods resolve media changer access, consult with Catalogic Software Data Protection Technical Support to troubleshoot. Before calling, have the following information ready:

    • Vendor make/model of the HBA adapter

    • Firmware version of HBA adapter

    • Version of HBA adapter OS drivers

    • Make and model of the tape library and tape drives

    • output.txt and error.txt files. These are generated from running: detect -q -d 3 1> output.txt 2>error txt
