After upgrading ONTAP to 9.5P4, you are seeing the following health monitor alert:
natestdal0505-ff::*> system health alert show
               Node: netapp_node_01
           Resource:  Link Aggregate 10
           Severity: Major
    Indication Time: Thu May 16 15:44:16 2019
           Suppress: false
        Acknowledge: false
     Probable Cause: The cable used to connect switch "netapp_switch_01/ Link
                     Aggregate 10" to the ISL port might be faulty.
    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 as per switch
                     configuration guide or by checking whether the Link
                     status LED is on.
