[cisco-voip] Unity Connection 10.5.2 Split Brain Recovery

[Jason Aarons (AM)]

Only time I’ve seen split brain in UC was when the customer built the VM with thin provisioning.  Seems their vm team did all sorts of things wrong….

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.
