SCSI_ADDRESS structure (ntddscsi.h)
The SCSI_ADDRESS structure is used in conjunction with the IOCTL_SCSI_GET_ADDRESS request to retrieve the address information, such as the target ID (TID) and the logical unit number (LUN) of a particular SCSI target.
Note The SCSI port driver and SCSI miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.
Syntax
typedef struct _SCSI_ADDRESS {
ULONG Length;
UCHAR PortNumber;
UCHAR PathId;
UCHAR TargetId;
UCHAR Lun;
} SCSI_ADDRESS, *PSCSI_ADDRESS;
Members
Length
Contains the length of this structure in bytes.
PortNumber
Contains the number of the SCSI adapter.
PathId
Contains the number of the bus.
TargetId
Contains the number of the target device.
Lun
Contains the logical unit number.
Remarks
Legacy class drivers issue the IOCTL_SCSI_GET_ADDRESS request to the port driver to obtain the address of their devices.
