What Should I Do If the SMN Function Works Improperly?

Updated at: Jul 25, 2019 GMT+08:00
  • During the creation of a migration task, the SMN function is unavailable.
    • After you click Add to select an SMN message topic, if the topic list displayed in the Select SMN Topic dialog box is empty, perform the following operations:

      Log in to the SMN console to check whether the topic exists. If the topic does not exist, create a new one.

    • After you click Add to select an SMN message topic, if the topic list displayed in the Select SMN Topic dialog box contains topics, but you cannot use a selected topic to create a migration task, perform the following operations:

      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 new one.

  • You have selected an SMN topic during the creation of a migration task and the migration task is successfully created, but the subscribers of the topic cannot receive the migration result notification.
    Ensure that the selected topic contains the required subscription that has been confirmed. Otherwise, notification messages sent using the SMN service 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.
