4.0 SU4ES here...
Trying to figure out any way to backup the primary headquarters CIC server without causing a switchover event. Would like to have automatic switchover but feel as if it needs to be configured as manual switchover (issue did not occur when in manual mode).
Situation:
2 x CIC servers, 1 at HQ 1 at DR site.
Both fully virtualized (VMWare).
HQ uses Veeam backup and it seems the notifier service dies during this backup window. Changed the backup time and the event logs indicating notifier service crash and switchover initiated follow the backup window, so it must be the backup. Currently set at 2 AM for backup (was 11 PM).
DR site uses Acronis vmProtect which runs earlier (think 10 PM).
Backups are successful, but switchover causes problems, especially polycom vvx500 phones. Random ones do not register, or when their SIP registration timer runs out, they do not re-register. Call Center Interaction Client preferences are all reset as well. Other than that people really do know that a switchover has taken place.
Is there a place in a config file or registry to make the auto switchover more relaxed? I understand when VEEAM consolidates snapshot disks, there are ping latencies increased to 300-900ms for a few seconds, with maybe 1 or 2 dropped packets in there. If we could relax the auto switchover to make it less "trigger happy" I would appreciate the advice!
