ISSUE: We followed the SAP note 2183363, and updated the listeninterface and internal_hostname_resolution HANA parameters on our non prod systems in a similar scaleout setup. These steps helped resolve the issue and the System Replication monitor was now reflecting all 3 TIERS Because site1 and site2 usually resides in the same data center but site3 is located very far in another data center. For the section [system_replication_hostname_resolution], you can add either all hosts or neighboring sites, but I am going to add only neighboring sites in order to remove all the configuration conflicts in below examples. Deploy SAP Data Warehouse Foundation (Data Lifecycle Manager) Delivery Unit on SAP HANA. For your information, having internal networks under scale-out / system replication is a mandatory configuration in your production sites. Have you already secured all communication in your HANA environment? Be careful with setting these parameters! Since quite a while SAP recommends using virtual hostnames. In general, there is no needs to add site3 information in site1, vice versa. secondary. Therefore, I would highly recommend to stick with the default value .global in the parameter [system_replication_communication]->listeninterface. Network and Communication Security.

After a validation on the non prod systems the change was made on our Production landscape that is using the HANA System Replication (HSR) Create virtual host names and map them to the IP addresses associated with client, communication, and, if applicable, SAP HSR network traffic. I haven't seen it yet, but I will link it in this post.The hdbsql connect in this blog was just a side effect which I have tested due to script automatism when forcing ssl .
