Data Domain systems automatically protect stability and recover from rare Fibre Channel (FC) anomalies. When unexpected conditions occur, the system may generate an automatic firmware dump on an FC target port. This alert (FCSSM‑00003) confirms the event occurred and was safely handled by the system. In most cases, this is a temporary condition and not a hardware failure.

If a Fibre Channel (FC) target port experiences repeated firmware dump events, the system may proactively disable the port to prevent ongoing disruption. Alert FCSSM‑00004 indicates this protective action has occurred. This behavior is intentional and protects overall system health.
