Hi, the CloudStack management server is "stateless" in that there is no important configuration on the mgmt server, and everything is in the database. When your mgmt server fails, you can recover quickly by installing CS on a new server and pointing it to the db (and probably a few other steps).
For clients accessing the web UI, there is session data and clients cannot switch between mgmt servers without logging in again. The docs hint to this in the load balancer configuration where it says connections to mgmt servers should be sticky and not random. If you are using the API with API/secret keys, there is no session info and you can switch between mgmt servers without a problem.
