Hi,
Is there a way I can send my own custom Ioctl to Scsi miniport driver
(scsiport object ) from a User mode App.
I am able to send system defined Ioctls but somehow when i send my own I
get *Incorrect Function* error. Also, all system defined Ioctls when
send translates to Srb with Function EXECUTE_SCSI while I thought they
shud have been with SRB_FUNCTION_IO_CONTROL.
If this is a normal behaviour when does FUNCITON_IO_CONTROL gets a hit…
Clues Plz.
TIA
Rahul
Hi Rahul, Look at DDK’s SPTI sample. It explains well.

you need to send IOCTL_SCSI_MINIPORT and include an SRB_IO_CONTROL structure as the input & output buffers.

You can send a vendor custom CDB in and SRB (EXECUTE SRB).

which works great until someone wants to use his controller with a
device that uses that vendors specific CDB code. And it would require
that his miniport set MappedBuffers which slows down all IO operations
just to handle this special case (assuming he doesn’t already do that).
IOCTL_SCSI_MINIPORT
