Hi @s_roy1982 , 

This is very well documented!!

See the following link: https://documentation.commvault.com/2023e/expert/server_installations_in_cluster_environment.html

Good luck!

Hi Onno van den Berg 

I have followed your document link and start the installation process but i have stuck one stage for CommVault fail over cluster installation that ERROR messages and log i have attached.

Please help me to come out this problem.

Regards 

Sudipta Roy

I can either be a name resolution issue or usage of an incorrect instance name for Commvault DB installation.
