574Routine Description:\r
575 Function to submit SCSI write 10 command.\r
576\r
577Arguments:\r
578 ScsiIo - A pointer to SCSI IO protocol.\r
579 Timeout - The length of timeout period.\r
580 SenseData - A pointer to output sense data.\r
581 SenseDataLength - The length of output sense data.\r
582 HostAdapterStatus - The status of Host Adapter.\r
583 TargetStatus - The status of the target.\r
584 DataBuffer - A pointer to a data buffer.\r
585 DataLength - The length of data buffer.\r
586 StartLba - The start address of LBA.\r
587 SectorSize - The sector size.\r
588\r
589Returns:\r
590\r
591 Returns:\r
592 EFI_SUCCESS - The status of the unit is tested successfully.\r
593 EFI_WARN_BUFFER_TOO_SMALL - The SCSI Request Packet was executed, \r
594 but the entire DataBuffer could not be transferred.\r
595 The actual number of bytes transferred is returned\r
596 in InTransferLength.\r
597 EFI_NOT_READY - The SCSI Request Packet could not be sent because \r
598 there are too many SCSI Command Packets already \r
599 queued.\r
600 EFI_DEVICE_ERROR - A device error occurred while attempting to send \r
601 the SCSI Request Packet.\r
602 EFI_INVALID_PARAMETER - The contents of CommandPacket are invalid. \r
603 EFI_UNSUPPORTED - The command described by the SCSI Request Packet\r
604 is not supported by the SCSI initiator(i.e., SCSI \r
605 Host Controller).\r
606 EFI_TIMEOUT - A timeout occurred while waiting for the SCSI \r
607 Request Packet to execute.\r
