Anybody from Microsoft: why WMI scsi miniport fails on XP

NTDEV
1

Hi

ANybody from Microsoft::

In the scsiMiniport
IoBuildDeviceIoControlRequest fails with return value

c00000c0 (STATUS_DEVICE_DOES_NOT_EXIST)

but I checked with WinObj tool(From Sysinternals) that our device exists
under //device//scsi//.
In win2K everything works fine, this problem comes only on XP when we enable
WMI.(If WMI disabled on XP it also works fine).

Any suggestion or hint to debug.

Regards
Pankaj

Have you reported any attached LUNs? I believe the WMI path still
requires a logical unit be attached in order to operate.

Let me get this straight … You are developing a SCSI miniport, using
SCSIPORT? If so, how did you get a call to IoBuildDeviceIoControlRequest to
work since it is not part of the SCSIPORT spec? Or did I miss something in
the spec?
