Problem description:
I need to make a cluster to take advantage of HA and other features. For the time being, I have only two ESXi 7 nodes to work with; a third one will be installed in several months. I've installed VCSA 7 on one of the ESXi nodes and discovered that I'm in a circular impossible situation: the cluster cannot be created because a VM (which is VCSA's VM) is running on one of the nodes, but of course if I terminate that VM, I cannot use VCSA, which runs on it, to create a cluster. I've spent several days looking at documentation without finding an answer to this problem. Directions for setting up clusters seem to assume that you have a third, uninvolved ESXi host on which to run VCSA. I do not want to devote an entire non-cluster node to running VCSA.
Questions:
1) What is the process to set up a two-node VSphere 7 cluster that supports the VCSA VM on that same cluster?
2) If I had started with 3 nodes, I could install VCSA on one of them and use it to generate the cluster for the other two. At that point, can I migrate the VCSA machine to the cluster and afterwards include the third node in the cluster?
