RAC Add Node

I am working on a virtualization first company for one of the largest Data Warehouse projects in the world for the financial industry to rapidly clone RAC clusters and databases in matter of hours.  We can provision up to 3 or 4 node RAC clusters in less than couple of hours and then as needed add nodes to the cluster with ease.

1. On target, create /u01/app/oraInventory (empty) and owned by oracle:dba

2. On the target node, please make sure /u01/app/11.2.0 directory is created and also empty. Make sure that it is owned by oracle:dba 
3. Run the following addnode.ksh on an existing RAC node with parameters replaced as oracle
4. You will be instructed to run root.sh on target node as root

The following are the caveats: 
1. cluvfy is buggy for 11.2.0.3. It had bugs in 11.2.0.2 also. I remember we had to set IGNORE_PREADDNODE_CHECKS to Y back in 11.2.02, and it looks like we still have to. 
2. /u01/app/oraInventory has to be pre-created and owned by oracle:dba and be completely empty 
3. /u01/app/11.2.0 has to be owned by oracle:dba. The /u01/app/11.2.0/grid directory cannot exist … even as an empty directory. The addnode.sh script attempts to do a “mkdir grid” as oracle, and if it fails, it dies. 
4. It died on me twice at “crsctl start listener -n “target_node” … have to create default listener first
5. I did not use the -noCopy method … This working example will copy the Grid Home from source RAC node to the new RAC node. I don’t think it is a big deal … added about 5 minutes to the overall time (see below).
