[ofw] SRP debugging level

[John Carbone]

Hi all,

The Mellanox SRP drivers for VMWare 5.1 enumerate the targets properly. So, I tried the Mellanox 2.1.3 driver and installed the HPC drivers, however even after manually installing SRP, the minport driver would not even start on in the driver manager.

So, I switched back to the OFED drivers. I dug around a little more in the registry, and found that the "DEVICEMAP" key also shows that the improper target enumeration, Scsi Port 5 & 6 are on two different targets:

[HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi\Scsi Port 5]
"Dma64BitAddresses"=dword:00000001
"Driver"="ibsrp"

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.
