Must be run on a host containing a running and connectable master aggregator.
This command connects to the master aggregator, sets
redundancy_level to 2, and then removes and re-adds half of the leaf nodes in the cluster into the second availability group.
This command will only work if all leaf nodes in the cluster share a user and password with the
This command is offline and will interrupt the currently running workload. It is best to run this command before adding any leaf nodes to the cluster.
This command is interactive unless you use either the
flags to override interactive behavior.
