You can try install using DUD method: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/... providing the megaraid_sas dd-megaraid_sas-07.707.51.00-1.el8_1.elrepo.iso from elrepo: https://elrepo.org/linux/dud/el8/x86_64/ When you complete your install before rebooting you can switch to Ctrl+Alt+F2 and go to a shell to verify some things chroot /mnt/sysimage lsinitrd /boot/initramfs-4.18.0-147.8.1.el8_1.x86_64.img | grep megaraid --> you should see the megaraid_sas module listed and also, as oVirt actually starts the initrd image under the layer, you should have an identical copy of the initrd here: lsinitrd /boot/ovirt-node-ng-4.4.0-0.20200506.0+1/initramfs-4.18.0-147.8.1.el8_1.x86_64.img | grep megaraid ---> you should see the megaraid_sas module listed if all is ok, you can exit the chroot environment, then Ctrl+Alt+F6 to come back to the graphical installer and click the reboot button and see if it is correctly seen by the os at restart. It works with plain CentOS 8, not tried with oVirt, but one guy reported he had problem at reboot: the system went into a dracut emergency shell not seeing the disk and so the LVM structures needed for proper start. You could try and report. Keep in mind that in case of deployment of the 4.4. GA you would have the same problem and also during upgrades. HIH, Gianluca

Just to avoid spending too much time with this, please note that Anaconda installer has a bug and DUD is not working on oVirt Node. If you need DUD you need to use CentOS and not oVirt Node. We are working with Anaconda Installer team to get this fixed but it will take time. I would also suggest to start planning an hardware refresh when budget will allow it. Dealing with obsoleted hardware won't help having a stable datacenter.
