During recent testing that I was completing within my home lab, I was repeatedly creating and decommissioning VMware vSAN configurations within a single cluster. The first time I completed this process, I was decommissioning a VMware vSAN OSA configuration prior to creating a new VMware vSAN ESA configuration on the cluster.
