What to do if the Dell SC4020 Center Startup Wizard cannot be completed and updates cannot be checked?
- M
  Michele BrayJul 28, 2025
  If you cannot complete the Storage Center Startup Wizard and are unable to check for updates, the management network might be using a proxy server that is blocking communication with the SupportAssist server. To resolve this: Use the Command Line Interface (CLI) to configure a proxy server for SupportAssist operations: 1. Establish a serial connection to the top storage controller. 2. Run the following commands: * `mc values set UsePhHomeProxy true` * `mc values set PhHomeProxyString [proxy server IP address]` * `mc values set PhHomeProxyUserName [proxy server username]` * `mc values set PhPomeProxyPassword [proxy server password]` 3. Complete the Storage Center Startup Wizard. 4. Check for Storage Center updates.

Why does the Dell SC4020 Storage license file show as invalid?
- S
  sericksonAug 1, 2025
  The license file may be invalid if you try to apply it before the storage controllers are joined, and the license file is applied to the storage controller with the higher serial number. Ensure that all Storage Center setup steps are followed in order and try again. Connect to the IP address of the storage controller with the lower serial number, and ensure the serial number in the license file name matches the storage controller.
