If you have executed root.sh on the installation of an Oracle 11g clusterware or RDBMS install and it failed. Remove the changes made by root.sh before re-execution with the following procedure.
1. Logon as the root user.
2. Navigate to the Oracle GRID_HOME
3. Execute the following command.
/opt/app/11.2.0/grid/crs/install/rootcrs.pl -deconfig –force -verbose
This completes the undoing the execution of root.sh from an Oracle Grid Installation.
