_SCSI_BUS_DATA structure

Description

The SCSI_BUS_DATA structure is used in conjunction with the IOCTL_SCSI_GET_INQUIRY_DATA request and the SCSI_ADAPTER_BUS_INFO structure to retrieve the SCSI inquiry data for all devices on a given SCSI bus.

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

`NumberOfLogicalUnits`

Contains the number of logical units on the bus for which inquiry data is being retrieved.

`InitiatorBusId`

Contains the SCSI bus ID for the adapter.

`InquiryDataOffset`

Contains an offset from the beginning of the SCSI_ADAPTER_BUS_INFO structure to the inquiry data.
