Hi Arun,
You need to run the setup script where it will ask the following
Where to install to? [/]: <ur path>
Would you like to install as a cluster? [no]:
Say yes for the above setup option and continue with the installation
Now you will find node1 & node2 simulators installed in the above given path. Install cluster license.
Run the setup script for each node and configure the interface which needs to take over a partner IP address during failover.
After reboot (mandatory since cluster is licensed) just enable cluster from the CLI.
Thanks
Daniel
