How to disable Hana system replication

  1. Stop the secondary system:

    sapcontrol -nr <instance_number> -function StopSystem HDB

  2. On secondary system unregister the secondary system:

    hdbnsutil -sr_unregister

  3. If you want to use this secondary as a normal SAP HANA installation from now on, you have to start it to complete the unregistration. On the secondary execute:

    sapcontrol -nr <instance_number> -function StartSystem HDB

  4. On primary system disable system replication:

    hdbnsutil -sr_disable
on
