On some of our machines (not Dell R730 series, so caveat emptor), I had to use the kmod-isci RPM from ELRepo.org to get EL8 hosts (both CentOS and RHEL) to recognize Intel SATA controllers. The same controller is recognized just fine by EL7 kernels, but the isci driver was removed in RHEL 8: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html-single/considerations_in_adopting_rhel_8/index#removed-device-drivers_hardware-enablement My suggestion is that you try finding a driver at http://elrepo.org/. -- Paul Heinlein heinlein at madboa.com 45°38' N, 122°6' W
