DeviceIoControl keep failing for scsi hard drive?

NTDEV

Hi Folks,
I call the below code to extract information about the scsi hard drive, it
consistently return me an error code of 1 (invalid function). Any hint on
how to debug or fix this error?
Thanks,
Huy

typedef struct IO_CONTROL
{
ULONG HeaderLength;
UCHAR Signature[8];
ULONG Timeout;
ULONG ControlCode;
ULONG ReturnCode;
ULONG Length;
} IO_CONTROL, *IO_CONTROL;

#define IOCTL_SCSI_MINIPORT 0x0004D008

if (DeviceIoControl ( ScsiDrive,
IOCTL_SCSI_MINIPORT,
buffer,
sizeof(IO_CONTROL)+ sizeof(SENDCMDINPARAMS)- 1,
buffer,
sizeof (IO_CONTROL) + SENDIDLENGTH,
&dummy, NULL))

Hi,

are you sure that miniport (?) you’re sending this IOCTL to does really
support IOCTL_SCSI_MINIPORT? This IOCTL is optional.

I think Anton has the answer. Your SCSI miniport may not support that
function. Besides are you sure that that is th e correct value?

How would I find out which option does the miniport supports?
Thanks,
Huy

Read the docs that came with the application development system. Call tech
support and ask. Where did you get the driver?

Oh … something else … your code fragment does not show the Signature
field being set. You must know what the signuature is for THAT version of
the miniport or it will be summarily rejected.

I initialized the signature with the above argument. I forgot to mention
that we used the standard Windows 2K driver.

Hmmmm “Standard Windows 2K driver”? Would that by any chance be controlling
the “standard Windows 2K HBA?”

Huy,

You’ll probably get more help if you tell us what you hope to achieve by
doing this. From what you’ve said it sounds like you don’t know what
driver your’re running against or which miniport IOCTLs (if any) it
supports.

It’s also not clear whether you’ve opened a handle to one of the devices
or to the adapter itself. I suspect miniport IOCTLs need to be directed
at the adapter (but I no longer remember) so you could also have the
same handle.

In any case - if you tell us what you want to accomplish we’ll be able
to tell you if this if miniport IOCTLs are the right mechanism or not
and go from there.

Peter is right. IOCTL_SCSI_MINIPORT must be sent to the adapter and not
to the device itself. We used to be lax on this but for the sake of
tighter security, IOCTLs not recognized by the PDO are no longer forwarded
to the FDO. They are failed w/ STATUS_INVALID_DEVICE_REQUEST.

Hi Peter,
You are right! I have to implement the sysInfo Mib for the agent which we
are implementing. Two of the scsi system that I have, have the default
installation without the manufacturers driver (just plain Windows 2K
installed). This is my first time writing device driver code to access
system information. Below is the code I used to create a handler to the
scsi device.

sprintf (driveName, “\\.\Scsi%d:”, controller);

hScsiDriveIOCTL = CreateFile (driveName,
GENERIC_READ | GENERIC_WRITE,
FILE_SHARE_READ | FILE_SHARE_WRITE, NULL,
OPEN_EXISTING,
0,
NULL);
thank so much,
Huy
