4.5 Installing the Unbreakable Enterprise Kernel

If the installed system is configured to use the Red Hat Compatible Kernel and the Unbreakable Enterprise Kernel (UEK) is not installed, you can use yum to install the kernel-uek package:

# yum install kernel-uek

Installing kernel-uek also installs the kernel-uek-firmware package on which it depends, and configures the UEK as the default kernel in /etc/grub.conf. Reboot the system to use this kernel.
