Using a Lin_tape Device Driver

To use a lin_tape device driver in the Commvault software, you need to install the driver, verify that the Commvault software detects it, and then set the reservation type according to the SCSI type that you are using.

The IBM lin_taped device driver is not currently supported on any Commvault Linux MediaAgent, including HyperScale.


  1. Download the lin_tape device driver on the computer on which the MediaAgent is installed. See Select Fixes Tape drivers and software, Tape device drivers (Linux).
  2. Install the IBM lin_tape device driver. See Installing the lin_tape device driver.

    Note: For HyperScale, contact Commvault Customer Support for lin_tape for IBM drivers. The package for lin_tape will be specifically built for the nodes and provided to you. For additional information, see Tape Library Support for HyperScale.

  3. To verify that the lin_tape device driver is installed and that the st driver is not running, enter the following command:

    lsmod | grep -i -E ‘st|lin_tape’

  4. In the dmesg log file, you can verify if the lin_tape device driver is attached at the operating system level. After the lin_tape device driver is attached, it is renamed as follows:
    • For IBM tape devices, the lin_tape is renamed to IBMtape(n).
    • For the arm, the lin_tape is renamed to IBMchanger(n)

    where (n) is the number of the device.

    For example, if you have three tape device drivers, the lin_tape attachments are IBMtape0, IBMtape1, and IBMtape2.

    The following excerpt of the dmesg log file displays the lin_tape device driver binding to one arm and one drive in a library.

  5. To verify that all devices are present at the operating system level, use the following command:

    cat /proc/scsi/IBM*

  6. To confirm that the Commvault detects the same devices that appeared in the dmesg log file and as a result of the cat command, do the following:
    • On the Linux MediaAgent, from the Base install directory of Commvault, run the ScanScsitTool tool.
  7. Do one of the following:
