How to get SCSI inquiry data from SFD ?

Hi,
Does anyone know how to get SCSI inquiry data from a SCSI filter
driver(SFD) layered on top of the disk SCSI class driver ? Is there a
way to send the IOCTL codes to the SCSI port driver and get that
information from the SFD ?

Thanks,
Unni

IOCTL_SCSI_GET_INQUIRY_DATA gets some inquiry data cached by SCSIPORT
for all the LUNs it discovered on that HBA (ScsiPortN device object).

If you want newer or different information than that, you’ll need to
build and issue the appropriate CDB/SRB via an IRP_MJ_SCSI IRP. Keep in
mind SCSIPORT will fail any request to a LUN it doesn’t know about.
