Analytical Ecosystem
Create a unique alias for every server with DNS or in the host files to make sure all servers in the failover cluster can connect to each other. The unique alias allows automatic failover reconfiguration without the need of a new IP address when the IP address of another server changes.
  1. Define all servers in the cluster by creating a unique alias in the DNS or the host files.
    Define the IP addresses in the /etc/hosts file if using the host file method.
  2. From the primary and secondary servers, add an entry to the /etc/hosts to make sure that the local server resolves to a publicly accessible IP address instead of 127.0.0.1.
    This allows DSA to run on a remote Data Mover agent and connect to the DSA REST running on the active Data Mover host.
