Wanting to monitor SRB activity between SCSIport/miniport driver

NTDEV

I’m looking for a way to monitor SRB’s being sent from the SCSIport driver
to the miniport driver. Is this possible? I already have a lower level
filter on the disk class driver to verify I/O requests are making it that
far down the driver stack, and I suspect the problem is in the miniport
driver (which I don’t have source to). The only thing I can think of is
to somehow intercept the StartIo routine in the miniport driver.

Thanks!
Bob

Set the breakpoing to its HwStartIo.

I forgot to mention that the problem I’m troubleshooting occurs hours into
my test, so setting a breakpoint isn’t feasible. I need to log the I/O
requests so I can keep track of them.

Thanks,
Bob
