[cisco-voip] Connection Split Brain

[STEVEN CASPER]

Yeah calls are hitting the sub and working ok even though they both think they are in charge. I was thinking that there was some services I could turn off on the subscriber to force the system back to normal.

I say that on a whim, I have not administered a Unity Connection cluster. But I figure if the publisher is up first advertising it's up, and the sub comes up after, it _should_ know it's not active.

I understood an inactive node becomes active when a call gets to it. Have people been reaching those ports?

Have you tried restarting the publisher first, then the subscriber?

Had a problem over the weekend with a Unity Connections subscriber server running 7.1.3 and the TAC recommendation was to rebuild. I did that but now the Connection Cluster is stuck in a split brain condition. Both the Sub and Pub think they are the primary. They can communicate as I can see the services for each system on both servers and the database appears to have replicated to the subscriber. I rebooted the sub but it came back in the same condition. Waiting for TAC to get back to me but I was wondering if anyone had any ideas in the mean time how to get the cluster back to normal operating state.
 
Thanks,
Steve
