Storport & Wmi

NTDEV
1

Hello,

I am trying to implement wmi in a storport driver and am seeing
Srb->DataPath==0 on a SRB_FUNCTION_WMI dispatch in startio.
According to the ddk this is should be a pointer to a guid.
Passing DataPath==0 to ScsiPortWmiDispatchFunction causes a fault in
scsiwmi.lib.
The ddk says that scsiwmi.lib handles registering classes, and storport
driver should not
have to do that. So why is Datapath ever coming in as zero and what i am i
supposed to
do with it ?
Any ideas ?

Thanks Rob.
