Hi Anil,
I recently installed the Production system in the same environment. please go through the installation guide Section 8 : High Availability with Microsoft Cluster Service. Please refer this section completely, let me know if you have any doubts.
1. Estimate and prepare the file system.
2. OS ADMIN will Configure the cluster and shows the report. the report should not contain any errors and warnings.
3. List out the IP addresses and Hostnames (refer the section 8.2.4 IP Addresses in an MSCS Configuration). Map the IP addresses to Hostnames.
Thanks
