Hello Guy's,
After I executed "yum update" and installed new kernels (redhat and UEK) the grub configuration is wrong it selected the redhat new installed kernel. we already review "/etc/sysconfig/kernel" and it is set by default UEK kernel.
yum update output said that we are updating those kernels versions:
/etc/sysconfig/kernel
after update:
To solve this issue I rebuilded grub.cfg with the following command: "grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg" rebooted and works..
I just wonder if this is related to this bug (https://docs.oracle.com/en/operating-systems/oracle-linux/7/relnotes7.7a/ol7-bug-22750169.html ), yum configuration looks correct, Please find below:
Any Idea?
Thank you Guys.
Regards.
