Issue

  • vifmgr.clus.linkdown is reported for a cluster network port in event logs:
Example:
[node-02: ixgbe/e0b: snmp.link.down:info]: Interface 2 is down.
[node-02: ixgbe/e0b: netif.linkDown:info]: Ethernet e0b: Link down, check cable.
[node-02: vifmgr: vifmgr.portdown:notice]: A link down event was received on node node-02, port e0b.
[node-02: vifmgr: vifmgr.clus.linkdown:EMERGENCY]: The cluster port e0b on node node-02 has gone down unexpectedly.
  • The network port is down even after SFPs on both the FAS side and the cluster network switch side are replaced.
  • The serial number of the new SFP on the FAS side is properly shown in the output of sysconfig -a.
  • The network cable is not faulty.
  • The network port link comes up when the cable is connected to another port of the switch.
