Symptoms

Even after setting up ssh, error results indicating 'passwordless ssh connectivity not setup between the nodes' while configuring Cluster using gridSetup.sh.

More details of the procedure as follows:

Invoke $GRID_HOME/gridSetup.sh and navigate to "Cluster Node Information" page. Give details of all the nodes and clicked "Next".

Output indicates passwordless ssh connectivity not setup between the nodes. Further, Click "SSH Connectivity", provide install user password and click "Setup", which setup ssh between the nodes.
SSH setup was successful with the message "Successfully established passwordless SSH connectivity between the selected nodes".

Still, next screen after click OK results passwordless ssh connectivity not setup between the nodes.
