I wanted to chime in and add a data point. I'm having the exact same issue with FreeNAS 11.1 U5 on a Dell PowerEdge R715 with an H200 controller. The installer doesn't even see all of the disks. It sees 5 of the 6 bays, it just doesn't see bay 5. However, I just ran the 11.0 U3 installer on it and it sees all 6 disks so it would seem to be something to do with 11.1.
