ATTO Fibre Bridge causing Link Failures on FC switch

Last Updated:

Applies to

  • Fabric MetroCluster
  • ATTO FB7500


  • Many link failure errors are observed on the switch ports connected to this ATTO bridge:
    • 2021/04/13-15:17:49, [PORT-1003], 111567, FID 128, WARNING, FabSW1, Port 11 Faulted because of many Link Failures.
  • The ATTO bridge itself cannot obtain FC port error counts:
    • get FCPortErrors all

      ; Fibre Channel Error Counts
      ; Port | Link Failures | Sync Loss | Signal Loss | Invalid Tx | Invalid CRC
         1        Error Obtaining FC Error Counts for port 1
         2        Error Obtaining FC Error Counts for port 2

  • Health Monitor reports the ATTO bridge in an 'error' state:
    • ClusterA::> storage bridge show
                                                                  Is        Monitor
