_SCSI_ADDRESS structure

Description

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.

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.
