Little setup-information to make the question a little more clear:
we have a windows server 2008r2 cluster which hosts some services (java based). All these services are cluster unaware atm and are clustered using a generic service container.
Now, we have noticed that some services can't seem to function properly after a failover and have determined that the problem is located with the use of the ip-adresses. As the services are cluster unaware, they will use the node ip-adress. So in fact, the ip that these services use depends on which node it is running.
Now, these services communicate communicate with cliënt which will only accept 1 ip. as it is configured to work with the ip of one node, a failover will mean that the service will not be able to communicate with the cliënt anymore.
Now, we have considered using preferred owners but that won't solve anything. Now, we have found the option " use network name for computer name". (generic service options - general).
If I put the network name resource as dependency, and i choose this option, will my service be able to resolve the ip and use the ip of the resource group instead of using the individual node ip? This would give us the option to change the Ip that the client accepts to the ip of the resource group
Can someone confirm this theory? Thanks a lot
