SCSI Pass Through protocol as defined in EFI 1.1. This protocol allows information about a SCSI channel to be collected, and allows SCSI Request Packets to be sent to any SCSI devices on a SCSI channel even if those devices are not boot devices. This protocol is attached to the device handle of each SCSI channel in a system that the protocol supports, and can be used for diagnostics. It may also be used to build a Block I/O driver for SCSI hard drives and SCSI CD-ROM or DVD drives to allow those devices to become boot devices.

| typedef EFI_STATUS(EFIAPI * EFI_SCSI_PASS_THRU_BUILD_DEVICE_PATH) (IN EFI_SCSI_PASS_THRU_PROTOCOL *This, IN UINT32 Target, IN UINT64 Lun, IN OUT EFI_DEVICE_PATH_PROTOCOL **DevicePath) |
Used to allocate and build a device path node for a SCSI device on a SCSI channel.
| This | Protocol instance pointer. |
| Target | The Target ID of the SCSI device for which a device path node is to be allocated and built. |
| Lun | The LUN of the SCSI device for which a device path node is to be allocated and built. |
| DevicePath | A pointer to a single device path node that describes the SCSI device specified by Target and Lun. This function is responsible for allocating the buffer DevicePath with the boot service AllocatePool(). It is the caller's responsibility to free DevicePath when the caller is finished with DevicePath. |
| EFI_SUCCESS | The device path node that describes the SCSI device specified by Target and Lun was allocated and returned in DevicePath. |
| EFI_NOT_FOUND | The SCSI devices specified by Target and Lun does not exist on the SCSI channel. |
| EFI_INVALID_PARAMETER | DevicePath is NULL. |
| EFI_OUT_OF_RESOURCES | There are not enough resources to allocate DevicePath. |

| typedef EFI_STATUS(EFIAPI * EFI_SCSI_PASS_THRU_GET_NEXT_DEVICE) (IN EFI_SCSI_PASS_THRU_PROTOCOL *This, IN OUT UINT32 *Target, IN OUT UINT64 *Lun) |
Used to retrieve the list of legal Target IDs for SCSI devices on a SCSI channel.
| This | Protocol instance pointer. |
| Target | On input, a pointer to the Target ID of a SCSI device present on the SCSI channel. On output, a pointer to the Target ID of the next SCSI device present on a SCSI channel. An input value of 0xFFFFFFFF retrieves the Target ID of the first SCSI device present on a SCSI channel. |
| Lun | On input, a pointer to the LUN of a SCSI device present on the SCSI channel. On output, a pointer to the LUN of the next SCSI device present on a SCSI channel. |
| EFI_SUCCESS | The Target ID of the next SCSI device on the SCSI channel was returned in Target and Lun. |
| EFI_NOT_FOUND | There are no more SCSI devices on this SCSI channel. |
| EFI_INVALID_PARAMETER | Target is not 0xFFFFFFFF, and Target and Lun were not returned on a previous call to GetNextDevice(). |

| typedef EFI_STATUS(EFIAPI * EFI_SCSI_PASS_THRU_GET_TARGET_LUN) (IN EFI_SCSI_PASS_THRU_PROTOCOL *This, IN EFI_DEVICE_PATH_PROTOCOL *DevicePath, OUT UINT32 *Target, OUT UINT64 *Lun) |
Used to translate a device path node to a Target ID and LUN.
| This | Protocol instance pointer. |
| DevicePath | A pointer to the device path node that describes a SCSI device on the SCSI channel. |
| Target | A pointer to the Target ID of a SCSI device on the SCSI channel. |
| Lun | A pointer to the LUN of a SCSI device on the SCSI channel. |
| EFI_SUCCESS | DevicePath was successfully translated to a Target ID and LUN, and they were returned in Target and Lun. |
| EFI_INVALID_PARAMETER | DevicePath is NULL. |
| EFI_INVALID_PARAMETER | Target is NULL. |
| EFI_INVALID_PARAMETER | Lun is NULL. |
| EFI_UNSUPPORTED | This driver does not support the device path node type in DevicePath. |
| EFI_NOT_FOUND | A valid translation from DevicePath to a Target ID and LUN does not exist. |

| typedef EFI_STATUS(EFIAPI * EFI_SCSI_PASS_THRU_PASSTHRU) (IN EFI_SCSI_PASS_THRU_PROTOCOL *This, IN UINT32 Target, IN UINT64 Lun, IN OUT EFI_SCSI_PASS_THRU_SCSI_REQUEST_PACKET *Packet, IN EFI_EVENT Event OPTIONAL) |
Sends a SCSI Request Packet to a SCSI device that is attached to the SCSI channel. This function supports both blocking I/O and non-blocking I/O. The blocking I/O functionality is required, and the non-blocking I/O functionality is optional.
| This | Protocol instance pointer. |
| Target | The Target ID of the SCSI device to send the SCSI Request Packet. |
| Lun | The LUN of the SCSI device to send the SCSI Request Packet. |
| Packet | A pointer to the SCSI Request Packet to send to the SCSI device specified by Target and Lun. |
| Event | If non-blocking I/O is not supported then Event is ignored, and blocking I/O is performed. If Event is NULL, then blocking I/O is performed. If Event is not NULL and non blocking I/O is supported, then non-blocking I/O is performed, and Event will be signaled when the SCSI Request Packet completes |
| EFI_SUCCESS | The SCSI Request Packet was sent by the host, and TransferLength bytes were transferred to/from DataBuffer. 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 DataBuffer could not be transferred. The actual number of bytes transferred is returned in TransferLength. 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 Request Packets already queued. The caller may retry again later. |
| EFI_DEVICE_ERROR | A device error occurred while attempting to send the SCSI Request Packet. See HostAdapterStatus, TargetStatus, SenseDataLength, and SenseData in that order for additional status information. |
| EFI_INVALID_PARAMETER | Target, Lun, or the contents of ScsiRequestPacket are invalid. The SCSI Request Packet was not sent, so no additional status information is available. |
| EFI_UNSUPPORTED | The command described by the SCSI Request Packet is not supported by the host adapter. 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. |
