I recently, upgraded the SUSE OS from SLES for SAP 12SP5 to SLES for SAP 15 SP3 on Power. Post upgrade, OS unable to detect the grub menus. I try to rebuild the bootloader it is failing with "ERROR: failed to lookup root id: Inappropriate ioctl for device". Anyone can address Grub2 issue on SLES on Power
