In environments integrating Spectrum with DX Operational Observability (DX O2), certain alarms, specifically 'Chassis Down' or 'Blade Status Unknown', may fail to clear in the DX O2 console even after they are cleared or resolved in Spectrum. This occurs when multiple rapid alarm events cause the connector to misidentify the alarm update target.
This issue is caused by a product defect (DE670730) where the connector becomes desynchronized when multiple alarms (such as a Chassis Down followed by a FRU Removal) occur in rapid succession. The connector incorrectly updates an existing alarm record instead of processing the clear for the original Alarm ID.
Fixed in release DX O2 OnPrem 26.1 HF#2 and higher.
