What Can I Do If SMN Is Not Working Properly?

  • SMN was not available during the creation of a migration task.
    • After you clicked Add to select an SMN message topic, the topic list displayed in the Select SMN Topic dialog box was empty.

      In this case, log in to the SMN console to check whether there are any topics. If there are no topics, create one.

    • After you clicked Add to select an SMN message topic, the topic list displayed in the Select SMN Topic dialog box contained topics, but you could not use a selected topic to create a migration task.

      In this case, log in to the SMN console to check whether the selected topic exists. If the topic does not exist, select another topic or create a topic.

  • You selected an SMN topic during the creation of a migration task and the migration task was successfully created, but the subscribers of the topic could not receive the migration result notifications.
    In this case, check that the selected topic contains the required subscription and that the topic has been confirmed. Otherwise, notification messages will not be sent to designated subscribers. A subscriber is a role that is subscribed to a topic. When you add a subscription, you need to specify the message sending destination. The following subscriptions are supported:
    • If it is an email subscription, the subscriber is an email address.
    • If it is an SMS subscription, the subscriber is a phone number.
    • If it is an HTTP or HTTPS subscription, the subscriber is a URL.

    For details about SMN, see Simple Message Notification.
