Managing a Backend Server Group

You can manage a backend server group as required.

Enabling Modification Protection

You can enable modification protection for a backend server group to prevent the backend servers in it from being modified or deleted by accident.

Enabling modification protection for a backend server group will prohibit any change to both the group and the backend servers in it.

  1. Go to the backend server group list page.
  2. On the displayed page, locate the backend server group and click its name.
  3. On the Summary tab, click Configure next to Modification Protection.
  4. In the Configure Modification Protection dialog box, enable Modification Protection.
  5. Click OK.

Disable Modification Protection if you want to delete a backend server group or modify its settings.

Enabling Removal Protection for a Backend Server Group

You can enable removal protection for a backend server group to prevent the backend servers in it from being removed by accident.

After removal protection is enabled for a backend server group, you cannot remove backend servers from it.

If your load balancer is managed by CCE, enabling removal protection for a backend server group may affect the normal running of the cluster.

  1. Go to the backend server group list page.
  2. On the displayed page, locate the backend server group and click its name.
  3. On the Summary tab, enable Removal Protection.

Disable Removal Protection if you want to remove servers from a backend server group.

Viewing a Backend Server Group

You can view the details of a backend server group.

  1. Go to the backend server group list page.
  2. On the backend server group list page, click the name of the backend server group.
  3. Click different tabs to view the required information.
    1. On the Summary tab, view the basic information (such as name, ID, backend protocol) and health check settings.
    2. On the Backend Servers tab, view the servers that have been added to the backend server group.
    3. On the Associated Resources tab, view the resources (load balancers, listeners, and forwarding policies) that are associated with the backend server group.

Deleting a Backend Server Group

Before deleting a backend server group, you need to:

  • Disassociate it from the listener. For details, see Changing a Backend Server Group.
  • Ensure the backend server group is not used by a forwarding policy of an HTTP or HTTPS listener.
  1. Go to the backend server group list page.
  2. On the backend server group list page, locate the backend server group and click Delete in the Operation column.
  3. In the displayed dialog box, click OK.
