      7. To review the new CWS hostname from the VPLEX side, in another PuTTY session login to the     
           VPLEX management server (either cluster is fine) with the service account credentials.     
     
      8. From the VPLEX management server prompt, SSH to the Cluster Witness Server IP address shown     
          here 128.221.254.3. You can also login using the public IP address   

   

           Example:   

   
      service@managementServer:~> ssh service@128.221.254.3     
      Last login: Tue Jul 23 18:35:10 2019 from 128.221.252.33       
        service@new-cws-name-here:~>
<<< new hostname showing on the CWS      
          
   
           You could also run the command  "hostname" at the CWS prompt to list the hostname.   
   

            Example:   

   

      service@cws-hostname:~> hostname       
        new-cws-name
