We had a 3 node existing cluster , here i am going to add a 4th node to it , to increase its capacity....
Here are the steps followed for the activity
[oracle@subdb01 bin]$export IGNORE_PREADDNODE_CHECKS=Y
[oracle@subdb01 bin]$ ./addNode.sh -silent "CLUSTER_NEW_NODES={subdb04}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={subdb04v}"

WARNING:
The following configuration scripts need to be executed as the "root" user in each new cluster node. Each script in the list below is followed by a list of nodes.
/oracle/grid/11.2.0.3/root.sh #On nodes subdb04
To execute the configuration scripts:
1. Open a terminal window
2. Log in as "root"
3. Run the scripts in each cluster node
The Cluster Node Addition of /oracle/grid/11.2.0.3 was successful.
Please check '/tmp/silentInstall.log' for more details.
====================================================================
Incase there was something wrong went and you want to clear up the things then please follow the steps below
====================================================================
http://docs.oracle.com/cd/E14072_01/rac.112/e10717/adddelclusterware.htm#BEIFDCAF
1) ensure grid home is set in both node1 and node 4
on node1
==========
[oracle@subdb01 bin]$ . oraenv
ORACLE_SID = [STGEXT_1] ? +ASM1
The Oracle base for ORACLE_HOME=/oracle/grid/11.2.0.3 is /oracle/app
[oracle@subdb01 bin]$ echo $ORACLE_HOME
/oracle/grid/11.2.0.3
on node4
===========
export ORACLE_HOME=/oracle/grid/11.2.0.3
2)
3)from 4th node
/oracle/grid/11.2.0.3/crs/install/rootcrs.pl -deconfig -force
4) from 1st node
crsctl delete node -n subdb04
5) from 4th node
./runInstaller -updateNodeList ORACLE_HOME=/oracle/grid/11.2.0.3 "CLUSTER_NODES={subdb04}" CRS=TRUE -local
6) on 4th node <manually clear up grid_home>
cd /oracle/grid/11.2.0.3
rm -rf $GRID_HOME instead of deinstall util and retry addnode.sh again
7) on first node
./runInstaller -updateNodeList ORACLE_HOME=/oracle/grid/11.2.0.3 "CLUSTER_NODES={subdb01,subdb02,subdb03}" CRS=TRUE
==============================
Root.sh script execution on node 4
==============================
We had some issues in root.sh script execution reason was because ACL was enabled.(Note: for ACL you can find a + sign in the file system and we asked our UNIX admin to disable it). We had some other issues also for ASM was not coming up , by the mean time we in process of fixing it.
