raid - HP Smart Array P400 controller reports physical drives incorrectly

I've been researching on this the majority of the day, when I had time to blow.



But now it's just becoming a headache, when I ask the HP P400 for detailed Information on the drives connected to the backplane it gives them all the same drive number, and model.
I believe it is related to the problem in http://www.motherboardpoint.com/hp-p400-raid-controller-reporting-p-disks-incorrectly-t232845.html but as far as I know this is the official HP Backplane, It's a HP SE 1102 server, all original.

HE103SJ does not represent every drive in the server, there is seagate constellations, and a WD RE4. (Weird combination, huh, don't ask why :P).




Does anyone have any idea what's going on here, and what solutions do I have if a drive fails, I cannot just delete 0:0 since I assume it'll delete all drives with the id "0:0".



Thanks!
