How can I implement MultipleRequestPerLu

NTDEV
1

Hi folks,

For a scsi miniport driver, I set MultipleRequestPerLu to TRUE in
DriverEntry and call ScsiPortNotification(NextLuRequest,
DeviceExtension, 0,0,0) when send READ/WRITE SRB to device. But my
driver still receivce SRB one by one. My driver cannot receive another
SRB before I call ScsiPortNotification(RequestComplete, DeviceExtension,
Srb). Does anything I forget to set?

Best regards – Wayne

Did you set TaggedQueuing in HW_INITIALIZATION_DATA?
Did the request SRB come in with PathId 0, TargetId 0, Lun 0?
