This command allows a user to replace one tape drive behind a
    Network Storage Router (NSR) with another tape drive at the same
    Fibre Channel (FC) Logical Unit Number (LUN) location.

    This command updates all the necessary file and memory data
    structures with the WWID of the new tape drive. The name of the
    replacement drive will be the same as the name of the original
    drive.

    This command is primarily intended to be used when a hardware
    problem occurs on a tape drive, and a replacement drive must
    installed in its place.

    The command requires CMKRNL privilege. It applies only to FC
    tapes behind a Fibre Channel tape bridge such as an NSR or MDR
    (Modular Data Router).

    For more information about Fibre Channel, see the Guidelines for
    OpenVMS Cluster Configurations.
