571Routine Description:\r
572 Function to submit SCSI write 10 command.\r
573\r
574Arguments:\r
575 ScsiIo - A pointer to SCSI IO protocol.\r
576 Timeout - The length of timeout period.\r
577 SenseData - A pointer to output sense data.\r
578 SenseDataLength - The length of output sense data.\r
579 HostAdapterStatus - The status of Host Adapter.\r
580 TargetStatus - The status of the target.\r
581 DataBuffer - A pointer to a data buffer.\r
582 DataLength - The length of data buffer.\r
583 StartLba - The start address of LBA.\r
584 SectorSize - The sector size.\r
585\r
586Returns:\r
587\r
588 Returns:\r
589 EFI_SUCCESS - The status of the unit is tested successfully.\r
590 EFI_WARN_BUFFER_TOO_SMALL - The SCSI Request Packet was executed, \r
591 but the entire DataBuffer could not be transferred.\r
592 The actual number of bytes transferred is returned\r
593 in InTransferLength.\r
594 EFI_NOT_READY - The SCSI Request Packet could not be sent because \r
595 there are too many SCSI Command Packets already \r
596 queued.\r
597 EFI_DEVICE_ERROR - A device error occurred while attempting to send \r
598 the SCSI Request Packet.\r
599 EFI_INVALID_PARAMETER - The contents of CommandPacket are invalid. \r
600 EFI_UNSUPPORTED - The command described by the SCSI Request Packet\r
601 is not supported by the SCSI initiator(i.e., SCSI \r
602 Host Controller).\r
603 EFI_TIMEOUT - A timeout occurred while waiting for the SCSI \r
604 Request Packet to execute.\r
