Issue

  • Cluster reports ClusterIfIslDownWarn after applying a new RCF.

               Node: NetappNode1
               Alert ID: ClusterIfIslDownWarn_Alert
               Resource: Ethernet1/32
     Severity: Major
        Indication Time: Thu Mar 07 08:48:42 2024
               Suppress: false
            Acknowledge: false
         Probable Cause: The cable used to connect switch
                         "Cluster-sw02(FDXXXXXXY)/Ethernet1/32" to the
       ISL port might be faulty. For the port-channel, please
                         check each individual link.
        Possible Effect: Cluster redundancy might be lost.
     Corrective Actions: 1) Check whether the cable is fully inserted into the interface port on both ends.
                         2) Reconnect the ISL port using another cable. After
                         reconnecting it, verify whether the link of the ISL
                         port is up by executing the commands per the switch
     configuration guide or by checking whether the Link
                         status LED is on.

  • Discrepancies observed in the actual RCF file and the output of show running-confg command from the switch.
