+### Data Outage Detected
+
+**Impact**: Availability
+
+**EMS Event**: `callhome.data.outage.detected`
+
+This message occurs when the system detects that it has encountered an outage prior to this boot.
+If your system is configured to do so, it generates and transmits an AutoSupport (or 'call home') message to NetApp technical support and to the configured destinations.
+Successful delivery of an AutoSupport message significantly improves problem determination and resolution.
+
+**Remediation**
+
+Contact NetApp technical support.
