+== Meaning
+
+This alert fires when more than one storage class has the annotation
+`storageclass.kubevirt.io/is-default-virt-class: "true"`.
+
+[discrete]
+[id="impact-cdimultipledefaultvirtstorageclasses"]
+== Impact
+
+The `storageclass.kubevirt.io/is-default-virt-class: "true"` annotation
+defines a default {VirtProductName} storage class.
+
+If more than one default {VirtProductName} storage class
+is defined, a data volume with no storage class specified
+receives the most recently created default storage class.

+== Diagnosis
+
+Obtain a list of default {VirtProductName} storage classes 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-cdimultipledefaultvirtstorageclasses"]
+== Mitigation
+
+Ensure that only one default {VirtProductName} storage class
+is defined by removing the annotation from the other storage classes.
+
+If you cannot resolve the issue, log in to the
+link:https://access.redhat.com[Customer Portal] and open a support case, attaching
+the artifacts gathered during the diagnosis procedure.
