Thank you so much for the documentation. I just ran into this same issue with a DS4246 and the NetApp HBA and have already bought the Dell controllers and an LSI 9201-16e yesterday out of desperation. This now confirms I’m not crazy nor the one person that’s had this issue. I just wish I would have found this post a week ago before spending all the time researching the problem that nobody else seemed to have. I have even went so far as to RMA the HBA, DS4246, and the QSFP cable. The new ones of those will be here Saturday but the Dell and LSI stuff won’t be here until Monday.
Also I did get my drives formatted but during boot/starting of the array drives would drop out randomly and I’d have to pull them out and reinsert them hoping they’d show up correctly.
