+== Meaning
+
+This alert fires when no default {product-title} or
+{VirtProductName} storage class is defined.
+
+[discrete]
+[id="impact-cdinodefaultstorageclass"]
+== Impact
+
+If no default {product-title} or {VirtProductName} storage
+class is defined, a data volume requesting a default storage class (the storage
+class is not specified), remains in a "pending" state.
+
+[discrete]
+[id="diagnosis-cdinodefaultstorageclass"]
+== Diagnosis
+
+. Check for a default {product-title} storage class by running
+the following command:
++
+[source,terminal]
+----
+$ oc get sc -o jsonpath='{.items[?(@.metadata.annotations.storageclass\.kubevirt\.io/is-default-class=="true")].metadata.name}'
+----
+
+. Check for a default {VirtProductName} storage class by running
+the following command:
++
+[source,terminal]
+----
+$ oc get sc -o jsonpath='{.items[?(@.metadata.annotations.storageclass\.kubevirt\.io/is-default-virt-class=="true")].metadata.name}'
+----
+
+[discrete]
+[id="mitigation-cdinodefaultstorageclass"]
+== Mitigation
+
+Create a default storage class for either {product-title} or
+{VirtProductName} or for both.
+
+A default {VirtProductName} storage class has precedence over a default
+{product-title} storage class for creating a virtual machine disk image.
+
+* Create a default {product-title} storage class by running
+the following command:
++
+[source,terminal]
+----
+$ oc patch storageclass <storage-class-name> -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
+----
+
+* Create a default {VirtProductName} storage class by running
+the following command:
++
+[source,terminal]
+----
+$ oc patch storageclass <storage-class-name> -p '{"metadata": {"annotations":{"storageclass.kubevirt.io/is-default-virt-class":"true"}}}'
+----
