## 3.2.1.3 Configure SAP HANA System Replication from the Primary and the Secondary Systems
To set up SAP HANA system replication, first enable system replication on the primary system and then register the secondary system. Use the SAP HANA cockpit to execute these configuration steps on the primary system and separately on the secondary system.
## Prerequisites
You have considered all the general prerequisites needed to set up system replication. For more information, see General Prerequisites for Setting Up SAP HANA System Replication .
## Context
This topic describes how to enable system replication on the primary system and then register the secondary system using the SAP HANA cockpit. You can use this method to configure any system replication setups you want.
##  Note
If you plan to add SAP HANA dynamic tiering to your landscape in the future, see SAP Note 2447994 before you enable HANA system replication. SAP HANA dynamic tiering requires certain communication ports, operation modes, and replication modes.
## Procedure
1. On the Overview page of the future primary system, choose the System Replication tile.
If you never configured system replication before, this tile displays the message System replication is not yet enabled for this system .
The System Replication page opens. If you performed a data backup before enabling system replication, this page displays overview information on the primary system on the top left and the Enable This System as Primary link on the top right.
2. Enter the logical name used to represent the primary system and choose Configure on the bottom right.
3. On the Overview of the future secondary system, choose the Overall Database Status tile.
4. Choose Stop System on the bottom right, because the system has to be offline in order to be registered as a secondary system.
Back on the Overview of the future secondary system, the Overall Database Status tile displays the status Stopped .
5. On the Overview page of the secondary system, choose the System Replication tile.
The System Replication page opens, displaying overview information about the secondary system on the top left and the Register Secondary System button on the top right.
6. Choose Register Secondary System .
The System Replication Configuration page opens.
7. On the System Replication Configuration page enter the logical name used to represent the secondary system.
8. On the System Replication Configuration page select a replication mode. For more information on the available replication modes, see Replication Modes for SAP HANA System Replication .
9. Select an operation mode. For more information on the available operation modes, see Operation Modes for SAP HANA System Replication .
10. Enter the host of the source system.
##  Note
If you are operating a distributed system on multiple hosts, enter the name of the host on which the master name server is running.
11. Check Start Secondary after Registration .
12. Review the configured information and choose Configure on the bottom right.
The System Replication Configuration dialog opens. After the configuration is complete, the System Replication Overview page displays information on the configured systems.
