 327   @retval EFI_SUCCESS               The status of the unit is tested successfully.
 328   @retval EFI_BAD_BUFFER_SIZE       The SCSI Request Packet was executed,
 329                                     but the entire DataBuffer could not be transferred.
 330                                     The actual number of bytes transferred is returned
 331                                     in InTransferLength.
 332   @retval EFI_NOT_READY             The SCSI Request Packet could not be sent because
 333                                     there are too many SCSI Command Packets already
 334                                     queued.

 336                                     the SCSI Request Packet.
 337   @retval EFI_INVALID_PARAMETER     The contents of CommandPacket are invalid.
 338   @retval EFI_UNSUPPORTED           The command described by the SCSI Request Packet
 339                                     is not supported by the SCSI initiator(i.e., SCSI
 340                                     Host Controller).

 342                                     Request Packet to execute.
