Hello I just moved a on prem always on sql availability group cluster to azure using azure migrate. There are 2 cluster IP resources...the cluster ip and the high availability group IP (lets say its 10.10.10.10/HAG.client.com). If i log into node 1 and node 1 owns the HAG IP resource in cluster manager then I can ping 10.10.10.10 from node 1 but I can't ping it from node 2. If i move the HAG role to node 2 then I can being 10.10.10.10 but then i can't ping from node 1. Do I need to add a load balancer rule to allow HA ports? I thought I remembered that working in the past. I don't want to make changes until i've tested if someone knows for sure I'd appreciate it. thanks a bunch!

    Hi anonymous user

    This is expected behavior when Failover Cluster networking interacts with the Azure networking. Clustered IP address resources and their associated Network Name resource differ from a regular IP address. Clustered IP address resources have limited functions and do not respond to ping requests over ICMP.

    The workaround is to try creating file share from active cluster nodes. Here is a link for a detailed description of this behavior.

    Error when you try to ping a Clustered Name that runs on Azure IaaS VMs: Request timed out

    Hope this resolves your Query!!
