Ok , let's discuss the original issue which is the clustering issue , as you can see in the logs , you have a flapping between your SA devices , as they is many messages kind of node unreachable , node reachable in your system logs , did you try to failover the VIP to the second device which you said is working , did you check the internal link (connected to internal NICs) for both nodes to make sure the fallaping is not due to cabling. could you please post screenshot of cluster status (Menu clustering --> Cluster status) Regards
