Hi, I'm trying to reactivate the failover for 2 Agents which were already members of a failover pair previously, but the failover connection was removed.
When trying to add the backup Agent again, Cube throws the following error:
At the same time, SLNet logs the following on the main Agent:
2023-08-22 13:13:29.650|210|Facade.HandleMessage|Incoming (Cube (Administrator @ DMA-PRD-01-MAIN)): Get IP Adapters for '192.168.0.43'
2023-08-22 13:13:29.650|210|Remoting.HandleMessages|Exception while handling Encrypted Messages (624 bytes): System.InvalidOperationException: Connection was already established before
at Skyline.DataMiner.Net.MessageBuilder.GetIPAdapters(IConnectionInfo connInfo, GetIpAdaptersMessage req)
Could you please suggest a possible solution?
Thank you.
Hi Laszlo,
To be able to configure failover again, you'll first have to clean the backup agent.
Could you share a screenshot of the c:Skyline DataMienrDMS.xml file from both servers?
Thanks for the hint. For some reason the DMS.xml on the main Agent referenced the main Agent with the virtual hostname of the failover pair. After modifying it to the IP of the Agent, the failover setup was restored fine.
Great to hear! Thanks for letting us know.
Hi Ive, I’ve run the reset tool, but it didn’t help, I still have the same error message. I think it’s something rather stuck on the main Agent, however there are no references of the backup IP address I’m trying to use in any of the configuration XMLs.
