Symptoms

This alert pertains to upgrading Storage Center controllers. It contains specific information related to system features and/or functionality. Alert: A Storage Center upgrade can involve upgrades to multiple components such as the Storage Center OS and/or firmware for the chassis, disks, and enclosures. Chassis firmware updates are a required upgrade which occur during the boot process of a Storage Center controller and cannot be deferred. Application of chassis updates require the controllers to reset sequentially. If chassis firmware updates are available, the Storage Center GUI Update Wizard may incorrectly indicate that a controller reset is not required. The Dell Storage Manager Update Wizard only reports if upgrade is "Service Affecting" or not and does not have a ‘controller reset yes/no’ field to indicate if a controller reset is required. Workaround: When choosing the option to "Apply updates that will not disrupt service" and click "Continue", The following screen will be displayed: Note the listed components being upgraded. Chassis firmware is noted with "DCIM:firmware" in the component name, similar to what is shown above. If such a component is listed, sequential controller resets will be required to complete the upgrade process and an appropriate maintenance window should be planned. Affected versions: All current SCOS versions and platforms
