We have a two node cluster in a failover configuration. The respective active node binds the cluster-IP to its NIC.
What's the right way to test availability of a service for the cluster? Setting up an RMA connection to the cluster IP somehow remembers, which was the active node and does not connect, if the other node is active. Is that because the host name is different now?
To measure the quality of service, it is of no concern which node is active. So there should be a way to test on the cluster-IP.
Thanks for suggestions.

How to test services on Cluster-IP
HostMonitor and RMA does not use any cache that can lead to such problem.Setting up an RMA connection to the cluster IP somehow remembers, which was the active node and does not connect, if the other node is active
I think Windows DNS cache should not be a problem as well. Cluster nodes utilize the same IP, right?
Unless you are using Active RMA installed on nodes of the cluster
Are you using Passive or Active RMA? Where RMA is installed? On clastered system? Some other regular system that is used to check clustered system?

I just found out about the problem:
After switching the active node, the arp cache of the system HostMonitor is running on, keeps the cluster-IP associated to the wrong MAC for quite a while. After I manually delete the cluster IP from the arp cache, everything works fine.
Thanks for help anyway
