Can you see if /dev/infiniband exists? If it does, the OpenFabrics
kernel drivers are running. If not, they aren't.

The OpenFabrics kernel drivers are implemented as kernel modules, so
it's mainly just a question of loading them it to start them running.
For example, in the official OFED distribution, it comes with /etc/
init.d/openibd -- "start" loads the kernel modules and does all the
necessary initialization, "stop" unloads everything, etc.

So if you have this init.d file, perhaps it's a question of checking
the chkconfig levels upon installation...?
