Routine Description:
|
|
Function tests the ready status of SCSI unit.
|
|
|
|
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.

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.

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.
