Device Objects for Logical Devices - PLEASE HELP!

NTDEV
1

Hello,

I have 8 physical devices (PHYSDEV) on my system (and the corresponding
Function Driver creates the FDO for each device as it is enumerated).

Each of these PHYSDEV devices can belong to one or more logical devices
(LOGDEV). There are 1-12 LOGDEVs on the system. I want my test
application to be able to open and perform i/o on any of these 12 LOGDEV
devices.

How can I accomplish this ?

Please, please help! I’ve run out of ideas.

Thanks
Puja

It may help to do the following.

Create some symbolic links.
e.g. \.\LogicalDev0 => \Device\PhysicalDev0
\.\LogicalDev1 => \Device\PhysicalDev0
\.\LogicalDev2 => \Device\PhysicalDev1
and so on.
