Codes_Translated

   The following MRD_ELEMENT codes are those currently supported by
   mrd_strelement(3mrd), with their corresponding default strings.

   The first items listed are self-explanatory.

   o  MRD_ELEMENT_TRANSPORT - Transport

   o  MRD_ELEMENT_SLOT - Slot

   o  MRD_ELEMENT_PORT - Port

   o  MRD_ELEMENT_DRIVE - Drive

   o  MRD_ELEMENT_EMPTY - Empty

   o  MRD_ELEMENT_FULL - Full

   o  MRD_ELEMENT_EXCEPT - Exception

   o  MRD_ELEMENT_ACCESS - Access

   o  MRD_ELEMENT_INPORT - Inport is suitable for use when the
      ELEMENT_IMPENB bit is set in the state and data.state field
      of the element_info_t data.

   o  MRD_ELEMENT_OUTPORT - OUTPORT is suitable for use when the
      ELEMENT_EXPENB bit is set in the state and data.state field of
      the element_info_t data.

   o  MRD_ELEMENT_IOPORT - IOPORT suitable for use when the ELEMENT_
      IMPENB and ELEMENT_EXPENB bits are set in the state and
      data.state field of the element_info_t data.

   o  MRD_ELEMENT_PASS - PassThru suitable in those cases where
      the Pass-through mechanism of the TL820 can be identified.
      Currently, the only way to do this is to know the absolute
      address of the PTM depending on whether the library is in
      Multi-unit Single-LUN (Transport 1) mode or Single-unit
      Single-LUN (Port 2) mode.

   o  MRD_ELEMENT_MYSTERY - This code is suitable when neither
      the ELEMENT_IMPENB nor ELEMENT_EXPENB bits are set in the
      state and data.state field of the element_info_t data. Most
      medium-changers identify their ports, when they have one
      or the other, or both. The MRD engineering team has never
      encountered a (correctly functioning) medium-changer with a
      Mystery Port.
