Thanks for looking into it.
I may want it to do more (or other) than that, as I am at the moment
concerned primarily with fibre channel. For me it would be ideal if I
could ignore the details and just invoke the portion of the “SCSI”
miniport driver that handles “target reset” in a way that is appropriate
for the actual underlying transport.
But I am still interested in hearing whatever you may turn up on the
use of pass-through.

What you want is to get the SCSI message BUS_DEVICE_RST sent to the
Target. Control over functionality at this low a level is desirable but
I don’t know if it is possible with SPTI. I’ll look into it.

Subject: [ntdev] SCSI target reset
Is it possible to reset a SCSI target on Windows 2000
(without resetting
the whole bus)? I’m trying to do this from a SCSI Adapter
upper filter.
I have pointers to the adapter FDO and LUN PDOs, and I’ve tried
targeting both.
I’ve tried IRP_MJ_SCSI w/ SRB_FUNCTION_RESET_DEVICE, and
IRP_MJ_DEVICE_CONTROL w/ IOCTL_STORAGE_RESET_DEVICE. Both fail with
STATUS_INVALID_DEVICE_REQUEST. The DDK documentation implies
that this
is the expected result.
But miniports have the option of supporting SRB_FUNCTION_RESET_DEVICE,
so why can’t I invoke it? When sending an SRB with function
other than
SRB_FUNCTION_EXECUTE_SCSI, does the stack location’s IoControlCode
matter?
While researching this I came across Aspi32 (Win95) docs that say that
API supports target reset. Does Aspi32 on NT/2000 support it as well
(and how)? Or does it just fail – or pretend to succeed – or reset
the bus?
What about Cluster Server – is it still resetting the whole bus when
a node wants to break the other’s reservation of the quorum disk?
Thanks,
