Currently we have only one node Data Repository server, and need to add two new servers to make a total of 3 nodes Data Repository servers cluster.
What is the correct process when adding two nodes to a single node Data Repository (DR) Vertica cluster?
When turning a single node DR cluster into a 3 node DR cluster do you add both nodes at the same time, or add both nodes one at a time?

The specific steps and instructions for adding a node to an existing DR cluster are found in the Add a Node to the Data Repository Cluster section.
When adding a single node to an existing DR cluster follow those steps from start to finish.
When adding two nodes to an existing DR cluster some steps can be done simultaneously. Some steps must be done individually, to each new host one at a time. The high level steps when adding two nodes at the same time are as follows. The specific steps/commands for each are found in the Add a Node to the Data Repository Cluster documentation.
