[cisco-voip] Unity Connection 10.5.2 Split Brain Recovery

[Aaron Banks]

Thank you for all of that.  You know what it was - NTP.  I shut down the HA.  NTP was doing weird things on the primary node and I asked the customer if the NTP server address he gave me was a windows server.  Bingo.  I changed the NTP source, rebooted the primary, called voicemail and then powered on the HA.

Lesson learned.

1.) Shut down the HA node.



2.) Reboot the primary node



3.) Once the primary node is up, place a call into voicemail 



4.) Power the HA node back on



5.) Once HA is up, verify HA status.

Has anyone seen/resolved a split brain recovery in Unity Connection 10.5.2?  The primary and secondary keep swapping back and forth every few minutes.  I can ping and trace to each server.  I restarted the primary but that did not resolve the issue.  In the
 RTMT system logs, the secondary sends an NTP query to the primary the response is the primary is inaccessible or down.  I'm stumped.
