An undesired DNS record that resolved to the VCF Operations IP address was present during the upgrade to 9.1.
When multiple DNS records resolve to the same VCF Operations IP address during the VCF 9.1 upgrade, an undesirable hostname may be saved to the SDDC Lifecycle database. Intermittent "Powered On" vs "Powered Off" statuses may be seen when both DNS records existed. If the incorrect DNS record is removed, the component will stay in a "Powered Off" state as the SDDC Lifecycle service could not resolve the recorded hostname.
