    Few nodes appears to be down after HA failover to Standby server




      I recently deployed HA in our customers environment which went well and successfully created pool.

      We changed the IP address of our standalone Main poller to a new IP and assigned the old IP as a VIP to avoid configuring network devices with a new SNMP hosts.


      When we failover to Standby server, it was observed that few nodes appears as down(while they are actually UP) and comes UP when we failback to Primary server.

      Has anyone faced similar issue?


      Talking about the choice of source IP address between VIP and polling engine IP for SNMP polling, the matching bits to default gateway are same(25 bits). So, int this case, what will be the source IP? Either VIP or polling engine IP?
