If the node group to be deleted originates from the logical cluster node group specified by src_group_name, set src_group_name to specify the logical cluster node group to which node information will be synchronized after redistribution. (The current feature is a lab feature. Contact Huawei technical support before using it.) This statement is used only for redistribution during scale-out. You are not advised to use it, because it may lead to data distribution errors and logical cluster unavailability.
