When you are required to stop an instance in an AS group for configuration or upgrade, disable the AS group before performing the operation. This prevents the instance from being deleted in a health check. When the instance status restores, enable the AS group again.
If a scaling action, for example, creating an instance or EVS disk, consistently fails (the failure cause can be viewed on the Elastic Cloud Server page) and retries in an AS group, use either of the following methods to stop the retry:
After an AS group is disabled, its status changes to Disabled. AS does not automatically trigger any scaling actions for a Disabled AS group. When an AS group has an in-progress scaling action, the scaling action does not stop immediately after the AS group is disabled.
You can disable an AS group when its status is Enabled or Abnormal.
