Yum update kernel does not boot into new kernel and /boot/grub2/grub.config is not existing

Latest response

Hello,
We are running RHEL 7.3.
We updated using yum update to latest kernel (kernel-3.10.0-862.14.4.el7.x86_64)

yum update kernel

And rebooted the system

pm -q kernel
kernel-3.10.0-327.el7.x86_64
kernel-3.10.0-514.10.2.el7.x86_64
kernel-3.10.0-862.14.4.el7.x86_64

But the system did not boot to latest kernel

uname -a
3.10.0-514.10.2.el7.x86_64

In fact the /boot/grub2/grub.conf does not exist

ls /boot | grep grub*

Why did the yum update fail to add to /etc/grub? and what is the solution

KH
