What authentication does dbadmin need to startup a cluster?
This question pertains to a DR situation. I have a three-node cluster. I'm restricting the authentication for dbadmin to localhost (and local subnet - do I even need this?). Suppose our local site is unavailable and I restore the cluster on a DR site where the IP addresses will have changed. I will need to re-ip the cluster before I can start it. If I defined the authentication for dbadmin to be only localhost, will the cluster be able to start up? I can't update the authentication until the db has started. We will have passwordless ssh of course.
