• System has error about SP no network connect in system health alert show

 ::> system health alert show
               Node: node1
 Alert ID: SPLinkDownAlert
           Resource: SP Config
           Severity: Major
    Indication Time: Tue Aug 27 23:50:13 2019
           Suppress: false
        Acknowledge: false
     Probable Cause: Service Processor in node node1 has no network
                     connectivity.The cable between the Wrench port on the
                     controller and the ethernet switch is disconnected.
    Possible Effect: You might not be able to use the Service Processor to
                     remotely access, monitor, and troubleshoot your
                     storage system.
Corrective Actions: 1. Check the connection between the Wrench port and the ethernet switch.
                     2. If the cable is properly connected, ensure that the Service Processor's ethernet interface is configured properly by 
                     executing the command "system service-processor network show".
                     3. Check for network cable related issues.
                     4. Contact the technical support if the alert persists.
