Best Regards, Strahil Nikolov In my case the DUD files didn't work (due to kernel version mismatch) on a couple of R710 (megaraid) and Generic-Intel-Xeon (isci SATA). As such, I use the manual path: - On a machine (or VM) running the latest CentOS 8 kernel: * Download the relevant DUD source RPMs (https://elrepo.org/linux/elrepo/el8/SRPMS/) and unpack them. (E.g. https://elrepo.org/linux/elrepo/el8/SRPMS/kmod-megaraid_sas-07.717.02.00-...) * From the module directory, manually build the missing kernel drivers by hand. (if you don't know what to do, follow the commands in the %build segment in the DUD spec file) and save the resulting .ko kernel modules (E.g. megaraid_sas.ko, isci.ko, etc). - Start the machine(s) using the CentOS8 stream installation USB. Wait for the first screen but *don't* do anything. - Switch to a console (Ctrl-Alt-F1). - Start the network and scp the newly built kernel modules into /lib/modules/$(uname -r)/extra - Load the newly copied kernel module using insmod. (E.g. insmod /lib/modules/$(uname -r)/extra/megaraid_sas.ko) - Check the kernel log (via dmesg) and make sure the storage controller has initialized correctly. - Switch back to the anaconda installer (Ctrl-Alt-F6 or F7). - Continue installation as usual. * (* I think I had to manually copy the kernel module to the newly installed machine, and dracut -f to get it included in the initramfs image, but I'm not certain). - Gilboa ________________________________ This message (and any associated files) is intended only for the use of the individual or entity to which it is addressed and may contain information that is confidential, subject to copyright or constitutes a trade secret.
