Goal

This articles describes how to clone an Oracle Grid Infrastructure home and use the cloned home to create a cluster. You perform the cloning procedures by running scripts in silent mode. The cloning procedures are applicable to 11.2.0.3 (and later) Clusterware installations on IBM: Linux on System z on both SuSE and Redhat.

This document does not cover using Cloning to Add Nodes to a Cluster.

This article assumes that you are cloning an Oracle Clusterware 11g release 2 (11.2) installation configured as follows:

No Grid Naming Service (GNS)

No Intelligent Platform Management Interface specification (IPMI)

Voting disk and Oracle Cluster Registry (OCR) are stored in Oracle Automatic Storage Management (ASM)

Single Client Access Name (SCAN) resolves through DNS

You should also refer to the following documentation:

 Oracle® Clusterware Administration and Deployment Guide
11g Release 2 (11.2)
Part Number E16794-16
http://docs.oracle.com/cd/E11882_01/rac.112/e16794/clonecluster.htm

This article can also be used in RDBMS clone for RAC. 

Please note that a fresh install of the Grid Install is recommended and is always less problematic  than cloning, with  GUI Grid Infrastructure Oracle Universal Installer guiding you through the configuration.  However, silent installs can save dbas time and effort when a large number of nodes need to be configured.
