[ofw] SRP debugging level

[John Carbone]

Hi Leonid,

I have to ask for your patience, as I'm not at all a windows developer and have no familiarity with WinDbg, so I may not be doing this correctly. 

When I attach to the kernel in WinDbg, this is output:
Microsoft (R) Windows Debugger Version 6.12.0002.633 AMD64

Don't you see the debug output in windbg ?

Hi all,

I downloaded and installed WinDbg, set the debug level to 4, set "bcdedit /debug on" and rebooted  but I do not know where to locate the debug output. I cannot determine if the targets are being enumerated and just not being reported to windows.

However, I tried setting one of the LUNs on the SAN filer to 1, and Windows maps the drive correctly every time now. So, I suspect that because the diskpart  is reporting that all the targets are zero Window is indeed getting confused as to which drive is which as I had suspected. 

Leonid, is this something you could please help with?

Did you try to install checked drivers and look into debug prints ? (DbgView or Windbg)

Re to  debug level: 
Many years ago you could have done it by setting DebugLevel/DebugFlags DWORD-32bit parameters in Registry (under Services\srp\parameters).
By default, DebugLevel was then 2 and DebugFlags 0xffff.
You can try to set DebugLevel to 3 or 4 and see what happen.
(All this is relevant only for checked drivers).

Hi all,

I'm trying to determine why SRP is not assigning target numbers with WinOF. Is there a way to change the debug level without compiling? Where can the output of SRP_PRINT be found?

Any help would be greatly appreciated. Thank you.

Kind regards,
John.
