// Abstract:
//
//    These are the structures and defines used in the Reduced Block Command set//

// Author:

//
//  Implementation Notes:
//      1. LUN
//          In SCSI-2, 3 bits LUN locates the highest 3 bits of the byte next to
//          OperationCode of the command Request.
//          In SCSI-3, 4 Bits LUN is controlled by Transport Protocol,
//              RBC and SPC-2 are parts of SCSI-3
