One node in my cluster is using ondemand governor which is specified in the directory /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor .. Scaling_governor allows us to choose the governor of our choice . But this sub-directory is absent in the other node of the cluster . How do I change the governor for Pstates in such case ?

Verify in your BIOS that you have something akin to "OS level power management" enabled.
