      The first SHOW DEVICE command displays information from the
      generic list about the unconfigured AG device. The ADD DEVICE
      command adds the device to the permanent list, and the MODIFY
      DEVICE command changes the unit number of the device. The
      second SHOW DEVICE command displays this change.
