Proliant DL120 G7 and Windows 2016 red disk lights

Hi All, 

I have a proliant DL120 G7 with two arrays. Array 1 is 2 x 1TB drives and Array 2 is 2 x 4TB drives. The raid card is the B110i

All the drives and arrays are seen fine in the Array bios setup and all disk lights green during boot. 

As soon as windows starts to loads the Array 2 disk lights go red and cant be seen in windows 2016. 

Any ideas?

Thanks
