Updating PowerFlex Manager and components Update the PowerFlex Manager virtual appliance before you update a component. After you update the virtual appliance, a notification banner might display at the top of the Services page. The banner alerts you that a service is in a critical state. To get the service into a healthy state, you must update the components if PowerFlex Manager added new required fields to any of the components. Use the PowerFlex Manager version applicable to the RCM. If you must upgrade the PowerFlex Manager virtual appliance to the supported latest version, PowerFlex Manager has an integrated mechanism for upgrading the PowerFlex Manager virtual appliance from an older version to the latest version. See the Dell EMC PowerFlex Rack Upgrade Guide for information about updating the PowerFlex Manager virtual appliance and incrementally upgrading PowerFlex rack software from one RCM to the next.
