It is not caching however. I will restart gpfs to see if that
makes it start working.<br>

I will try that. I was attempting to not need to write a custom
udev rule for those. Also to keep the names persistent. Rhel 7
has a default rule that makes a sym link in /dev/disk/by-id.<br>

Thanks Matt. I admit I'm somewhat grasping at straws here.<br

That's a *really* long device path (and nested too), I
