Updating Backend Server IP Addresses in OCI Load Balancer Backend Sets after DR operation
Issue: After performing switchover, failover, or start drill DR operations, there is a slight possibility that the load balancer may not pass traffic to newly launched resources, such as compute instances that were added as backend servers in the load balancer backend set on the new primary region.
Solution: To verify whether the load balancers added to the DR protection group are functioning correctly, check each load balancer and ensure that their health checks are successful. If you find that the health checks are failing, you must update the IP addresses of the respective load balancer's backend servers in the backend set.
