Description of problem:
Hi,

In the Documentation for "DEPLOYING RED HAT HYPERCONVERGED INFRASTRUCTURE FOR VIRTUALIZATION ON A SINGLE NODE":
"Single node deployments cannot be scaled, and are not highly available."
https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure_for_virtualization/1.5/html-single/deploying_red_hat_hyperconverged_infrastructure_for_virtualization_on_a_single_node/index

But instead in the general Deploying guide, this statement seems to leave door open for 1 node deployment and its scale up to 3:

"Red Hat Hyperconverged Infrastructure for Virtualization is supported for one node, and for clusters of 3, 6, 9, and 12 nodes.

The initial deployment is either 1 or 3 nodes."
https://access.redhat.com/documentation/en-us/red_hat_hyperconverged_infrastructure_for_virtualization/1.5/html-single/deploying_red_hat_hyperconverged_infrastructure_for_virtualization/#rhhi-req-scaling


Is the scaling up from 1 to 3 supported or not?

Version-Release number of selected component (if applicable):
RHHI-V 1.5
