The version of grid infrastructure and oracle home used here is 11.2.0.2, which is the patch upgrade but could also be used for a fresh installation. The cluster here was a fresh installation created from this patch set. RAC database is of two instances and admin-managed. Here the two nodes are called rac4 (DB instance rac11g11) and rac5 (DB instance rac11g12), and rac5 will be removed.
1. Backup the ocr using ocrconfig -manualbackup
2. Run DBCA from a node that will remain in the cluster and select instance management and delete instance. In the subsequent steps select the instance on the node that will be removed from the cluster and proceed to finish step. This instance that's being removed must be up and running.
3. Check if the redo log thread for the deleted instance is removed by querying the v$log if not remove it with
alter database disable thread thread#4. Check if the instance is removed from the clustersrvctl config database -d rac11g2

Database is administrator managedAs seen from above only one instance is present. This conclude the first phase of the node removal. Next is to remove the Oracle Home.5. Check if any listeners are running on the oracle home to be deleted. In 11.2 the default listener runs from grid home. But if any listeners were explicitly created on oracle home then it must be disabled and stopped.
Check from which home listener is running
srvctl config listener -a Name: LISTENER Network: 1, Owner: oracle Home:Since it's running from grid home this step could be skipped if it was running from oracle home use the following commands to disable and stop it/opt/app/11.2.0/grid on node(s) rac5,rac4 End points: TCP:1521
$ srvctl disable listener -l listener_name -n name_of_node_to_delete $ srvctl stop listener -l listener_name -n name_of_node_to_delete6. Run the following on the node to be deleted to update the inventory.
cd $ORACLE_HOME/oui/bin

./runInstaller -detachHome ORACLE_HOME=Oracle_home_locationFor non shared home run deinstall from the oracle home on the node that's being removed with -local option.
If -local is not specified this will apply to the entire cluster.
