+
+Routine Description:
+ Function to submit SCSI write 10 command.
+
+Arguments:
+ ScsiIo - A pointer to SCSI IO protocol.
+ Timeout - The length of timeout period.
+ SenseData - A pointer to output sense data.
+ SenseDataLength - The length of output sense data.
+ HostAdapterStatus - The status of Host Adapter.
+ TargetStatus - The status of the target.
+ DataBuffer - A pointer to a data buffer.
+ DataLength - The length of data buffer.
+ StartLba - The start address of LBA.
+ SectorSize - The sector size.
+
+Returns:
+
+ Returns:
+ EFI_SUCCESS - The status of the unit is tested successfully.
+ EFI_WARN_BUFFER_TOO_SMALL - The SCSI Request Packet was executed,
+ but the entire DataBuffer could not be transferred.
+ The actual number of bytes transferred is returned
+ in InTransferLength.
+ EFI_NOT_READY - The SCSI Request Packet could not be sent because
+ there are too many SCSI Command Packets already
+ queued.
+ EFI_DEVICE_ERROR - A device error occurred while attempting to send
+ the SCSI Request Packet.
+ EFI_INVALID_PARAMETER - The contents of CommandPacket are invalid.
+ EFI_UNSUPPORTED - The command described by the SCSI Request Packet
+ is not supported by the SCSI initiator(i.e., SCSI
+ Host Controller).
+ EFI_TIMEOUT - A timeout occurred while waiting for the SCSI
+ Request Packet to execute.
