I have a minimal installation on a HP Proliant Microserver Gen8. I have installed a RocketRaid 622 card in the PCI slot to which is attached by eSata cable a Sans Digital TR4M drive enclosure containing 4 x WD Red NASWare 3TB drives. During boot the RR622 BIOS is called and after scanning for disks displays the details of the four drives. Fedora 23 then boots. After booting I can not see the drives attached to the RR622.
