[cisco-voip] CUC Cluster replication issues

[Mike Lydick]

Are the NTP server windows based NTP? I have had many issues using windows
NTP because the clocks slip. So the effect will be that NTP will slip in/out
of sync.

Check your NTP, high stratum or unsynchronized or insane NTP clocks can
cause Unity Connection Database replication to fail. Fix the ntp status and
resolves the issue

 

Utils ntp status

Looking for ntp to have a peer and the state is synch'd

Hey Guys,

 

  Noticed we were having Unity Connection cluster issues when I logged.  I
went ahead and restarted the Pub first and then the Sub as this was the fix
that TAC gave me last time we had a similar issue.  However, it still having
issues.  Please see output below from each server.
