Cause
The installation has been done with -ignorePrereq option

Solution
1> Clean deinstall this oracle home
Do ensure to run the cluster verification utility and fix all Warning and Failures reported by cluvfy utility and re-run the installation
you can run cluvfy for single instance as shown below
$GRID_HOME//runcluvfy.sh stage -pre hacfg

and for RAC

$GRID_HOME//runcluvfy.sh stage -pre crsinst -n node1,node......noden

Note:(node1,node2...noden are the list of RAC nodes)
