The procedures and syntax for activating the host drivers in each kernel type are the same except for the kernel file names. So, for example, when you are required to enter a value for the kernel-filename option, you can enter either one of the following values depending on the host OS running on the server:
kernel-uek-2.6.39-400.204.0.el5uek.x86_64.rpm (for a UEK2 kernel type)
kernel-uek-3.8.13-19.el6uek.x86_64.rpm (for a UEK3 kernel type)
