590Routine Description:\r
591 Function to submit SCSI write 10 command.\r
592\r
593Arguments:\r
594 ScsiIo - A pointer to SCSI IO protocol.\r
595 Timeout - The length of timeout period.\r
596 SenseData - A pointer to output sense data.\r
597 SenseDataLength - The length of output sense data.\r
598 HostAdapterStatus - The status of Host Adapter.\r
599 TargetStatus - The status of the target.\r
600 DataBuffer - A pointer to a data buffer.\r
601 DataLength - The length of data buffer.\r
602 StartLba - The start address of LBA.\r
603 SectorSize - The sector size.\r
604\r
605Returns:\r
606\r
607 Returns:\r
608 EFI_SUCCESS - The status of the unit is tested successfully.\r
609 EFI_WARN_BUFFER_TOO_SMALL - The SCSI Request Packet was executed, \r
610 but the entire DataBuffer could not be transferred.\r
611 The actual number of bytes transferred is returned\r
612 in InTransferLength.\r
613 EFI_NOT_READY - The SCSI Request Packet could not be sent because \r
614 there are too many SCSI Command Packets already \r
615 queued.\r
616 EFI_DEVICE_ERROR - A device error occurred while attempting to send \r
617 the SCSI Request Packet.\r
618 EFI_INVALID_PARAMETER - The contents of CommandPacket are invalid. \r
619 EFI_UNSUPPORTED - The command described by the SCSI Request Packet\r
620 is not supported by the SCSI initiator(i.e., SCSI \r
621 Host Controller).\r
622 EFI_TIMEOUT - A timeout occurred while waiting for the SCSI \r
623 Request Packet to execute.\r
