EFI_STATUS EFIAPI ScsiInquiryCommand ( IN EFI_SCSI_IO_PROTOCOL ScsiIo,
IN UINT64  Timeout,
IN OUT VOID *  SenseData,
IN OUT UINT8 SenseDataLength,
OUT UINT8 HostAdapterStatus,
OUT UINT8 TargetStatus,
IN OUT VOID *  InquiryDataBuffer,
IN OUT UINT32 InquiryDataLength,
IN BOOLEAN  EnableVitalProductData 
)

Execute Inquiry SCSI command on a specific SCSI target.

Executes the Inquiry command on the SCSI target specified by ScsiIo. If Timeout is zero, then this function waits indefinitely for the command to complete. If Timeout is greater than zero, then the command is executed and will timeout after Timeout 100 ns units. If ScsiIo is NULL, then ASSERT(). If SenseDataLength is NULL, then ASSERT(). If HostAdapterStatus is NULL, then ASSERT(). If TargetStatus is NULL, then ASSERT(). If InquiryDataLength is NULL, then ASSERT().

If SenseDataLength is non-zero and SenseData is not NULL, SenseData must meet buffer alignment requirement defined in EFI_SCSI_IO_PROTOCOL. Otherwise EFI_INVALID_PARAMETER gets returned.

If InquiryDataLength is non-zero and InquiryDataBuffer is not NULL, InquiryDataBuffer must meet buffer alignment requirement defined in EFI_SCSI_IO_PROTOCOL. Otherwise EFI_INVALID_PARAMETER gets returned.

Parameters:
[in] ScsiIo A pointer to the SCSI I/O Protocol instance for the specific SCSI target.
[in] Timeout The timeout in 100 ns units to use for the execution of this SCSI Request Packet. A Timeout value of zero means that this function will wait indefinitely for the SCSI Request Packet to execute. If Timeout is greater than zero, then this function will return EFI_TIMEOUT if the time required to execute the SCSI Request Packet is greater than Timeout.
[in,out] SenseData A pointer to sense data that was generated by the execution of the SCSI Request Packet. This buffer must be allocated by the caller. If SenseDataLength is 0, then this parameter is optional and may be NULL.
[in,out] SenseDataLength On input, the length in bytes of the SenseData buffer. On output, the number of bytes written to the SenseData buffer.
[out] HostAdapterStatus The status of the SCSI Host Controller that produces the SCSI bus containing the SCSI target specified by ScsiIo when the SCSI Request Packet was executed. See the EFI SCSI I/O Protocol in the UEFI Specification for details on the possible return values.
[out] TargetStatus The status returned by the SCSI target specified by ScsiIo when the SCSI Request Packet was executed on the SCSI Host Controller. See the EFI SCSI I/O Protocol in the UEFI Specification for details on the possible return values.
[in,out] InquiryDataBuffer A pointer to inquiry data that was generated by the execution of the SCSI Request Packet. This buffer must be allocated by the caller. If InquiryDataLength is 0, then this parameter is optional and may be NULL.
[in,out] InquiryDataLength On input, a pointer to the length in bytes of the InquiryDataBuffer buffer. On output, a pointer to the number of bytes written to the InquiryDataBuffer buffer.
[in] EnableVitalProductData If TRUE, then the supported vital product data is returned in InquiryDataBuffer. If FALSE, then the standard inquiry data is returned in InquiryDataBuffer.
Return values:
EFI_SUCCESS The command was executed successfully. See HostAdapterStatus, TargetStatus, SenseDataLength, and SenseData in that order for additional status information.
EFI_BAD_BUFFER_SIZE The SCSI Request Packet was executed, but the entire InquiryDataBuffer could not be transferred. The actual number of bytes transferred is returned in InquiryDataLength.
EFI_NOT_READY The SCSI Request Packet could not be sent because there are too many SCSI Command Packets already queued. The SCSI Request Packet was not sent, so no additional status information is available. The caller may retry again later.
EFI_DEVICE_ERROR A device error occurred while attempting to send SCSI Request Packet. See HostAdapterStatus, TargetStatus, SenseDataLength, and SenseData in that order for additional status information.
EFI_UNSUPPORTED The command described by the SCSI Request Packet is not supported by the SCSI initiator(i.e., SCSI Host Controller). The SCSI Request Packet was not sent, so no additional status information is available.
EFI_TIMEOUT A timeout occurred while waiting for the SCSI Request Packet to execute. See HostAdapterStatus, TargetStatus, SenseDataLength, and SenseData in that order for additional status information.
EFI_INVALID_PARAMETER The contents of the SCSI Request Packet are invalid.

IN UINT64  Timeout,
IN OUT VOID *  SenseData,
IN OUT UINT8 SenseDataLength,
OUT UINT8 HostAdapterStatus,
OUT UINT8 TargetStatus 
)

Execute Request Sense SCSI command on a specific SCSI target.

Executes the Request Sense command on the SCSI target specified by ScsiIo. If Timeout is zero, then this function waits indefinitely for the command to complete. If Timeout is greater than zero, then the command is executed and will timeout after Timeout 100 ns units. If ScsiIo is NULL, then ASSERT(). If SenseDataLength is NULL, then ASSERT(). If HostAdapterStatus is NULL, then ASSERT(). If TargetStatus is NULL, then ASSERT().

If SenseDataLength is non-zero and SenseData is not NULL, SenseData must meet buffer alignment requirement defined in EFI_SCSI_IO_PROTOCOL. Otherwise EFI_INVALID_PARAMETER gets returned.

Parameters:
[in] ScsiIo A pointer to SCSI IO protocol.
[in] Timeout The length of timeout period.
[in,out] SenseData A pointer to output sense data.
[in,out] SenseDataLength The length of output sense data.
[out] HostAdapterStatus The status of Host Adapter.
[out] TargetStatus The status of the target.
Return values:
EFI_SUCCESS Command is executed successfully.
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 SCSI Request Packet.
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.
EFI_INVALID_PARAMETER The contents of the SCSI Request Packet are invalid.

IN UINT64  Timeout,
IN OUT VOID *  SenseData,
IN OUT UINT8 SenseDataLength,
OUT UINT8 HostAdapterStatus,
OUT UINT8 TargetStatus 
)

Execute Test Unit Ready SCSI command on a specific SCSI target.

Executes the Test Unit Ready command on the SCSI target specified by ScsiIo. If Timeout is zero, then this function waits indefinitely for the command to complete. If Timeout is greater than zero, then the command is executed and will timeout after Timeout 100 ns units. If ScsiIo is NULL, then ASSERT(). If SenseDataLength is NULL, then ASSERT(). If HostAdapterStatus is NULL, then ASSERT(). If TargetStatus is NULL, then ASSERT().

If SenseDataLength is non-zero and SenseData is not NULL, SenseData must meet buffer alignment requirement defined in EFI_SCSI_IO_PROTOCOL. Otherwise EFI_INVALID_PARAMETER gets returned.

Parameters:
[in] ScsiIo A pointer to the SCSI I/O Protocol instance for the specific SCSI target.
[in] Timeout The timeout in 100 ns units to use for the execution of this SCSI Request Packet. A Timeout value of zero means that this function will wait indefinitely for the SCSI Request Packet to execute. If Timeout is greater than zero, then this function will return EFI_TIMEOUT if the time required to execute the SCSI Request Packet is greater than Timeout.
[in,out] SenseData A pointer to sense data that was generated by the execution of the SCSI Request Packet. This buffer must be allocated by the caller. If SenseDataLength is 0, then this parameter is optional and may be NULL.
[in,out] SenseDataLength On input, a pointer to the length in bytes of the SenseData buffer. On output, a pointer to the number of bytes written to the SenseData buffer.
[out] HostAdapterStatus The status of the SCSI Host Controller that produces the SCSI bus containing the SCSI target specified by ScsiIo when the SCSI Request Packet was executed. See the EFI SCSI I/O Protocol in the UEFI Specification for details on the possible return values.
[out] TargetStatus The status returned by the SCSI target specified by ScsiIo when the SCSI Request Packet was executed on the SCSI Host Controller. See the EFI SCSI I/O Protocol in the UEFI Specification for details on the possible return values.
Return values:
EFI_SUCCESS The command was executed successfully. See HostAdapterStatus, TargetStatus, SenseDataLength, and SenseData in that order for additional status information.
EFI_NOT_READY The SCSI Request Packet could not be sent because there are too many SCSI Command Packets already queued. The SCSI Request Packet was not sent, so no additional status information is available. The caller may retry again later.
EFI_DEVICE_ERROR A device error occurred while attempting to send SCSI Request Packet. See HostAdapterStatus, TargetStatus, SenseDataLength, and SenseData in that order for additional status information.
EFI_UNSUPPORTED The command described by the SCSI Request Packet is not supported by the SCSI initiator(i.e., SCSI Host Controller). The SCSI Request Packet was not sent, so no additional status information is available.
EFI_TIMEOUT A timeout occurred while waiting for the SCSI Request Packet to execute. See HostAdapterStatus, TargetStatus, SenseDataLength, and SenseData in that order for additional status information.
EFI_INVALID_PARAMETER The contents of the SCSI Request Packet are invalid.
