For a volume containing installed products, records a change in
    volume label in the product database.

    For device independence, the product database identifies the
    destination device of an installed product by its logical volume
    name, not by its physical device name. The logical volume name
    (usually in the form DISK$labelname) is defined by the MOUNT
    command and associated with the device.
