How to get PCI Bus# user mode

NTDEV
1

Hi all,

Is there a way to map a PCI-based SCSI Port to its associating PCI Bus location from user mode?
For example, in HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\Scsi\Scsi Port 5 (Emulex LP8000 card, driver: elxstor.sys) , I want to know the PCI Bus location of the adapter/controller, like “PCI Bus 3, Device 7, Function 0”

I am familiar with SetupDixxx and the SCSI setup class GUID.

Thanks in advance

use SPDRP_LOCATION_INFORMATION like this:
TCHAR fname[256];
SetupDiGetDeviceRegistryProperty(info, &did, SPDRP_LOCATION_INFORMATION,
NULL, (PBYTE) fname, sizeof(fname), NULL))

where did is SP_DEVINFO_DATA (from SetupDiGetDeviceInterfaceDetail(…)
and info is HDEVINFO info (from SetupDiGetClassDevs(…)

Robin,
Thanks for the suggestion.
But how do I tell SetupDixxx that this is Scsi Port 5, for example, that I am looking for? Could you elaborate?

Thanks

Why do you care that it’s port 5 vs. port 4? Obviously you want to
uniquely identify which controller it is, but the port number isn’t the
way to do that as the port number can change across boots.

You can find all the storage port devices using SetupDi to find all
instances of the device interface GUID_DEVINTERFACE_STORAGEPORT (this
will show all port drivers, scsi or not) and query each for the
information. You can reuse the name that SetupDi gives you for the
device interface across reboots to uniquely identify that device (as
long as it isn’t moved - PCI devices don’t have unique IDs that would
allow the system to track devices moving slots).

So what are you actually trying to do?

Hi Peter,

Our server has so many PCI slots, and our application wants to keep track of what adapter/controller is in what slot so that it can tell the user, in case of hardware failure or hardware removal/insertion between boots, that it detects the change, and smart enough hopefully, it can tell the corresponding slot.

Ultimately, we want to get the PCI Slot#, given PCI Bus#, Device#, Function#.

We can use SetupDi to query all “SCSI and RAID Controllers” devices, and find out the PCI Bus#, Device#, and Function#. I want to know the PCI Slot# as well, but I dont know how.

Thanks

If by slot number you mean a physical PCI bus slot, good luck on that. I
think that has been discussed here in this group and I think the consensus
was that given the variation in platforms out there it was not really
feasible to come up with a scheme that would reliably identify a physical
slot.
