The Installer shows no disk at all in system it has 6 seen by 4.3.9.
oVirt 4.4. is based on CentOS 8, where megaraid_sas driver (the one driving
PERC5) has been removed, being a rebuild of Red Hat 8:
You can try install using DUD method:
providing the megaraid_sas dd-megaraid_sas-07.707.51.00-1.el8_1.elrepo.iso
When you complete your install before rebooting you can switch to
Ctrl+Alt+F2 and go to a shell to verify some things
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:
| 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.
