Verify the update and Azure Stack Hub functionality

Once the update has been applied successfully, it can take some time (two hours or more) for Azure Stack Hub to “settle down” and return to normal behavior. During the update process and this settling period, alerts may appear based on infrastructure component availability.

You can verify that the update has been applied by checking the version of the current environment in the Azure Stack Hub Administrator Portal. Return to the dashboard and click Update to open the Update blade. Check that the “Current OEM version” is as expected.

The Azure Stack Hub validation tool (Test-AzureStack) is a PowerShell cmdlet that lets you run a series of tests on your system to identify failures if present. It is a recommended practice to run the Test-AzureStack cmdlet after applying each update. See here for Microsoft’s current instructions for performing this test: https://docs.microsoft.com/en-us/azure/azure-stack/azure-stack-diagnostic-test.
