This A pointer to the EFI_SCSI_PASS_THRU_PROTOCOL
instance. Type EFI_SCSI_PASS_THRU_PROTOCOL is
defined in Section 13.1.
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 .
