addNode.sh failed with PRCF-2023 while transfering files between RAC nodes

ORACLE GRID 11.2.0.4, Database 11.2.0.3

addNode.sh failed with below error.
./addNode.sh "CLUSTER_NEW_NODES={d002}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={d002-vip}"

PRCF-2023 : The following contents are not transferred as they are non-readable.
Directories:

   1) /u01/app/11.2.0.4/grid/home_2/crs/utl

This directory is owned by root, permissions are 740 on this directory where as addNode.sh is being as 'grid' user. Hence I modified the permissions as chmod -R o+r utl.

utl directory will have four files which need 755 permissions. Make sure these permissions exist. 
-rwxr-xr-x 1 root root  4555 Apr 22 07:40 rootaddnode.sh
-rwxr-xr-x 1 root root  5190 Apr 22 07:40 rootdeinstall.sh
-rwxr-xr-x 1 root root  5992 Apr 22 07:40 rootdelete.sh
-rwxr-xr-x 1 root root  1954 Apr 22 07:40 rootdeletenode.sh

After this change addNode.sh was successfully completed.
