4. Open a web browser, enter the IP address of the Calamari node and after logging in a prompt will request to execute: sudo ceph-deploy calamari connect --master master_host node1 node2 ...
5. Reload or refresh the web interface, login and verify everything is working after clicking the "ADD" button to add all the hosts listed under "Hosts Requesting to Be Managed By Calamari".
