I am new to clustering.
1. If I create a cluster with 2 nodes and shared storage, and keep my application running on node1, client applications will be connecting to my application on node1. In the event of a failover, when the application starts on node2, will the client applications need to change the IP address to which they were connecting? Or will VCS show a single IP address to the external world so that client applications do not need to be reconfigured?
2. Can I configure VCS to start my application on node2 automatically in the event of failover, without any manual intervention?
Solved! Go to Solution.
Please remember that that a failover service group does not give you 'always on'.
It gives you failover.
This means that all resources are brought offline on node1 and brought online on node2.
This will result in application being unavailable until all resources are online on node2.
As per above excellent post, if you can configured a virtual IP address in the service group, the users will connect to the same IP address.
Because of the interruption during failover, users will probably have to reconnect.
