You can rename database by creating control file as well , like we use to do in single instance database.
1) Shutdown node 2
2) Run following command on node 1
alter database backup control file to trace ;
3) shutdown database on node 1
4) copy trace file created in step 2 to file crctl.sql (say) . Edit crctl.sql and set database name what u want to set.
5) edit init<sid>.ora and change database name
6) startup nomount and run crctl.sql
7) Startup database in both node
8) Change tnsnames.ora and listener.ora ( if needed)
9) config srvctl
srvctl remove database -d <old_database_name>
srvctl add database -d <new_db_name> -o $ORACLE_HOME
srvctl add instance -d <new_db_name> -i <instance name on node 1> -n Node1
srvctl add instance -d <new_db_name> -i <instance name on node 2> -n Node2
