I have installed Rocky 8.6 on an old PowerEdge R710 with a PERC 6/i raid controller using the elrepo megaraid drivers. Installation went fine, but after the reboot it ends up on the grub command line and it cannot see the drives anymore.
So how do I load these raid drivers again and make sure that they will be loaded every time this machine boots?
Should I have done something during the installation process to add these drivers to the system? I was expecting that they would be installed automatically since I supplied them to the installer.
Is secure boot enabled? Perhaps it’s stopping the module from loading and causing the grub screen? If you disable secure boot and the system boots fine, you may need to follow this if you want secure boot enabled: ELRepo | SecureBootKey
Yes, but there is a tiny issue … the “success” of installer.
The Secure Boot requires that bootloader, kernel, and kernel modules are all signed with certificates that the UEFI can verify. One has to upload the certificate oo ELRepo into UEFI, before it can verify ELRepo driver modules.
If the UEFI cannot verify ELRepo driver, then the installer could not load the DUD and show the volumes attached to the RAID controller
If the installer can show the volumes, then Secure Boot is either disabled or can verify the same ELRepo module when loaded by the installed kernel
