Hello
We are setting up Hana System Replication.
Our landscape is composed by 2 Appliances HANA SUSE 11.3:
Hana Revision: 93.
All tests relative to HSR (Hana System Replication) are working except one: deactivating Replication.
In detail:
- Activating Replication is working ok
- Registering secondary node and data replication (from node1 to node2) is well working
- Performing takeover from node1 to node2 is ok
- Registering node1 to node 2 and data replication (from node2 to node1 ) is ok
- Performing failback from node2 to node1 is ok
But the issue appears if I want deactivate replication:
- Unregistering secondary node (using hdbnsutil -sr_unregister or hana Studio) it semms ok and database node2 starts ok.
- But if I deactivate replication definitively ( using command hdbnsutil -sr_disable or using Hana Studio) , it seems is ok, but database node 2 can be restarted anymore.
Always we see an error on trace file of Hana node2 saying :
“[104819]{-1}[-1/-1] 2015-07-16 12:09:25.203190 f NameServer TREXNameServer.cpp(03338) : landscape ID mismatch between nameserver.ini/[landscape]/id (5570cb6a-22c4-8035-e100-00000a010154) and topology.ini (556eb908-bc3c-9cbf-e100-00000a010152)
-> stopping instance ...
It seems deactivation replication is not well working…
.. In this situation we only can do Activation replication from node 1, and register node 2 to 1, and then we establish again replication 1 –> 2. But we can’t deactivate it definitively.
Any suggestion?
Thanks and regards
