Unity Connection 7.1 Hostname to IP

7.1.5ES18.31900-18 pair with cluster config referencing hostnames - which I need to change to the IP addresses to get around DNS dependency.

What is needed after this change?  Reboot?  Restart a service?  Cluster replication subscription reissue?

Reboot each server after the change and then verify replication via RTMT and/or CU Reporting.

Hi,

As long as DNS is not enabled or if you are going to disable DNS ( requires reboot of servers ), it does not affect whether  you use hostname or IP under

         CUC Admin web page > System settings > cluster

In such scenarios, the  DB / OS resolves server names in cluster with the help of local file  (  /etc/hosts - updated during installation / reboot )

You can verify it by

show tech network hosts

show network eth0 detail

In addition, you verify the cluster status by executing

show cuc cluster status

on both servers
