Re: Sending custom IOCTL to a STORPORT miniport driver

Max,

The SRB_IO_CONTROL structure uses an 8 byte Signature field and a 32 bit
ControlCode field. Those two fields are defined by and are unique for each
vendor. I know what they are for LSI because I have the LSI docs that define
them, have used them and know the IOCTL_SCSI_MINIPORT works, but what works
for LSI will not work for Adaptec. The SCSIPORT miniport will verify the
contents of those two fields and bounce the request if it does not like what
it sees.

For IOCTL_SCSI_MINIPORT, the SRB_IO_CONTROL structure contains OEM
private
fields that require you to get that information from the driver
manufacturor. Do you have that information, and is it correct for the
firmware in the HBA?

I would much rather send IOCTL_SCSI_MINIPORT to \\.\physicaldriveX as
well.
However, it doesn't work - fails with error code 1 (incorrect
function).
Only works with \\.\scsiX:.

I think I found a thread from a few years back where people including
yourself talk about a similar problem as well:

http://www.tech-archive.net/Archive/Development/microsoft.public.development.device.drivers/2005-01/0995.html
My impression from that discussion is that I should be able to send
IOCTL_SCSI_MINIPORT to \\.\physicaldriveX, but thats not the case.
