This error is due to the wrong lsnodoes in DB_HOME.
The solution is to create the following symbolic link from GI Home to DB home on Node1 before adding the 2nd node.
As the oracle db user (oradba):
$ export GRID_HOME=/u01/app/12.1.0.2/grid
$ export DB_HOME=/u01/app/oracle/product/12.1.0.2/db_1
$ cd $DB_HOME/oui/bin
$ mv lsnodes lsnodes.old
$ ln -s $GRID_HOME/bin/olsnodes $DB_HOME/oui/bin/lsnodes
$ ln -s $GRID_HOME/bin/olsnodes.bin
$DB_HOME/oui/bin/lsnodes.bin
Now retry to add the oracle home on 2nd node.
