Resolution

1. Ensure that all nodes have forward and reverse DNS entries on the configured DNS server.
2. Ensure that the vApp options for the Aria Operations for Logs node has the "hostname" key configured in vCenter
3. Take a snapshot without memory for the affected node(s)
4. SSH the node using root credentials the run this command
   
   /opt/vmware/bin/init/set_hostname.py
   
   
5. Logout of the SSH/console session and login again, the hostname should now be configured correctly (Lifecycle should now also be able to sync the environment)
