+Set the default StorageClass
+----------------------------
+
+In some ONAP components it is important to have a default storageClass defined (e.g. cassandra),
+if you don't want to explicitly set it during the deployment via helm overrides.
+
+Therefor you should set the default storageClass (if not done during the K8S cluster setup) via the command:
+
+    > kubectl patch storageclass <storageclass> -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
+
+see `DefaultStorageClass`_
