Tape drivefirmware is checked whenever a tape drive is reset, such as when thelibrary is power cycled or restarted, or whenever a tape drive is added orreplaced. If the firmware does not match, the tape drive firmware isautoleveled.FC tape drives must be connected to an FC I/O blade or an EthernetExpansion blade to participate in autoleveling operations.
