During the regular maintenance of HANA DB , do we need to disable the hana replication

0 Kudos

we have 2 node based hana replication enabled for our HANA DB. I would like to know if we need to un-register the secondary node during the maintenance or we can simply shutdown both the systems and then turn them back on once maintenance is done. what would be best approach here ? could you even provide some supporting document for this.

Hi Ashu,

I think the information "Best Approch During Maintenance" you are looking for is described in section 10.9 Upgrade and Maintenance on the How To document below.

How To Perform System Replication for SAP HANA

My opinion : there is no need to unregister the secondary system unless it goes out of sync and all the attemps to get it in sync fails.
