I am getting connection refused error when I try to register secondary system in system replication

Hello,

The error is due to the fact that hostname is not properly maintained. You will need to Maintain the primary site hostname in HANA Studio exactly in the way it is returned by the select statement against m_topology_tree. The steps to resolve the issue is documented in SAP note 2050830 - Registering a secondary system via HANA Studio fails with error 'remoteHost does not match with any host of the source site'

Cheers,

At first please do not use Rev. 121.00 anymore. There are a lot of bugs regarding system replication in this revision. Check that both host can use reverse-/DNS resolution. On the other hand you can also use the HANA internal hostname resolution. Check the official documentation on 10.6.1 which depends on your NICs and host setup.

Jens
