Windows Server 2016, drives missing

Hi, I got an NL410 with 36 drives installed.

When i ran with it with truenas all the drives showed and were up and runnning with ZFS. 

But i had some software limitations for my applications which made me go over to windows server 2016.

I have checked beforehand and the NL410 should work with WS2016. 

But i can only see 11 drives inside och windows now, tried reinstalling drivers and none seem to do the trick.

Am i missing something or is there anything that is required for this to work?
