| typedef EFI_STATUS(EFIAPI * EFI_EXT_SCSI_PASS_THRU_BUILD_DEVICE_PATH) (IN EFI_EXT_SCSI_PASS_THRU_PROTOCOL *This, IN UINT8 *Target, IN UINT64 Lun, OUT EFI_DEVICE_PATH_PROTOCOL **DevicePath) |
Used to allocate and build a device path node for a SCSI device on a SCSI channel.
| This | A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance. |
| Target | The Target is an array of size TARGET_MAX_BYTES and it specifies the Target ID of the SCSI device for which a device path node is to be allocated and built. Transport drivers may chose to utilize a subset of this size to suit the representation of targets. For example, a Fibre Channel driver may use only 8 bytes (WWN) in the array to represent a FC target. |
| 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_INVALID_PARAMETER | DevicePath is NULL. |
| EFI_NOT_FOUND | The SCSI devices specified by Target and Lun does not exist on the SCSI channel. |
| EFI_OUT_OF_RESOURCES | There are not enough resources to allocate DevicePath. |

| typedef EFI_STATUS(EFIAPI * EFI_EXT_SCSI_PASS_THRU_GET_NEXT_TARGET) (IN EFI_EXT_SCSI_PASS_THRU_PROTOCOL *This, IN OUT UINT8 **Target) |
Used to retrieve the list of legal Target IDs for SCSI devices on a SCSI channel. These can either be the list SCSI devices that are actually present on the SCSI channel, or the list of legal Target IDs for the SCSI channel. Regardless, the caller of this function must probe the Target ID returned to see if a SCSI device is actually present at that location on the SCSI channel.
| This | A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance. |
| Target | (TARGET_MAX_BYTES) of a SCSI device present on the SCSI channel. On output, a pointer to the Target ID (an array of TARGET_MAX_BYTES) of the next SCSI device present on a SCSI channel. An input value of 0xF(all bytes in the array are 0xF) in the Target array retrieves the Target ID of the first 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. |
| EFI_INVALID_PARAMETER | Target or Lun is NULL. |
| EFI_TIMEOUT | Target array is not all 0xF, and Target was not returned on a previous call to GetNextTarget(). |
| EFI_NOT_FOUND | There are no more SCSI devices on this SCSI channel. |

| typedef EFI_STATUS(EFIAPI * EFI_EXT_SCSI_PASS_THRU_GET_NEXT_TARGET_LUN) (IN EFI_EXT_SCSI_PASS_THRU_PROTOCOL *This, IN OUT UINT8 **Target, IN OUT UINT64 *Lun) |
Used to retrieve the list of legal Target IDs and LUNs for SCSI devices on a SCSI channel. These can either be the list SCSI devices that are actually present on the SCSI channel, or the list of legal Target Ids and LUNs for the SCSI channel. Regardless, the caller of this function must probe the Target ID and LUN returned to see if a SCSI device is actually present at that location on the SCSI channel.
| This | A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance. |
| Target | On input, a pointer to the Target ID (an array of size TARGET_MAX_BYTES) of a SCSI device present on the SCSI channel. On output, a pointer to the Target ID (an array of TARGET_MAX_BYTES) of the next SCSI device present on a SCSI channel. An input value of 0xF(all bytes in the array are 0xF) in the Target array 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 and LUN of the next SCSI device on the SCSI channel was returned in Target and Lun. |
| EFI_INVALID_PARAMETER | Target array is not all 0xF, and Target and Lun were not returned on a previous call to GetNextTargetLun(). |
| EFI_NOT_FOUND | There are no more SCSI devices on this SCSI channel. |

Used to translate a device path node to a Target ID and LUN.
| This | A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance. |
| DevicePath | A pointer to a single device path node that describes the SCSI device on the SCSI channel. |
| Target | A pointer to the Target Array which represents the 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 or Target or Lun is NULL. |
| EFI_NOT_FOUND | A valid translation from DevicePath to a Target ID and LUN does not exist. |
| EFI_UNSUPPORTED | This driver does not support the device path node type in DevicePath. |

| typedef EFI_STATUS(EFIAPI * EFI_EXT_SCSI_PASS_THRU_PASSTHRU) (IN EFI_EXT_SCSI_PASS_THRU_PROTOCOL *This, IN UINT8 *Target, IN UINT64 Lun, IN OUT EFI_EXT_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 nonblocking I/O. The blocking I/O functionality is required, and the nonblocking I/O functionality is optional.
| This | A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance. |
| Target | The Target is an array of size TARGET_MAX_BYTES and it represents the id of the SCSI device to send the SCSI Request Packet. Each transport driver may choose to utilize a subset of this size to suit the needs of transport target representation. For example, a Fibre Channel driver may use only 8 bytes (WWN) to represent an FC target. |
| 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 nonblocking 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 nonblocking 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. For bi-directional commands, InTransferLength bytes were transferred from InDataBuffer. For write and bi-directional commands, OutTransferLength bytes were transferred by OutDataBuffer. |
| EFI_BAD_BUFFER_SIZE | The SCSI Request Packet was not executed. The number of bytes that could be transferred is returned in InTransferLength. For write and bi-directional commands, OutTransferLength bytes were transferred by OutDataBuffer. |
| 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. |
| EFI_INVALID_PARAMETER | Target, Lun, or the contents of ScsiRequestPacket are invalid. |
| EFI_UNSUPPORTED | The command described by the SCSI Request Packet is not supported by the host adapter. This includes the case of Bi-directional SCSI commands not supported by the implementation. 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. |

| typedef EFI_STATUS(EFIAPI * EFI_EXT_SCSI_PASS_THRU_RESET_CHANNEL) (IN EFI_EXT_SCSI_PASS_THRU_PROTOCOL *This) |
Resets a SCSI channel. This operation resets all the SCSI devices connected to the SCSI channel.
| This | A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance. |
| EFI_SUCCESS | The SCSI channel was reset. |
| EFI_DEVICE_ERROR | A device error occurred while attempting to reset the SCSI channel. |

Resets a SCSI logical unit that is connected to a SCSI channel.
| This | A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance. |
| Target | The Target is an array of size TARGET_MAX_BYTE and it represents the target port ID of the SCSI device containing the SCSI logical unit to reset. Transport drivers may chose to utilize a subset of this array to suit the representation of their targets. |
| Lun | The LUN of the SCSI device to reset. |
| EFI_SUCCESS | The SCSI device specified by Target and Lun was reset. |
| EFI_INVALID_PARAMETER | Target or Lun is NULL. |
| EFI_TIMEOUT | A timeout occurred while attempting to reset the SCSI device specified by Target and Lun. |
| EFI_UNSUPPORTED | The SCSI channel does not support a target reset operation. |
