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