SwitchInfoUpdateFailure_Alert after Motherboard Replacement in MetroCluster IP Fabric

Applies to

Issue

• After replacing the motherboard (MB) and DIMM in slot 2 on Node1 of a MetroCluster IP configuration, the following persistent alert appears in ONTAP:

cluster::*> system health subsystem alert show
               Node: cluster-02
           Alert ID: SwitchInfoUpdateFailure_Alert
           Resource: IP_switch_A_1
     Probable Cause: Information from the Ethernet switch 'IP_switch_A_1'
                     is no longer being updated. Other switch alerts might
                     indicate possible causes for the issue.
    Possible Effect: When switch information is not being updated,
                     monitoring of the switch's performance and health has
                     stopped, potentially leading to unnoticed issues,
                     service disruptions, and loss of communication.
                     Furthermore, the log collection configuration will be
                     deleted after 7 days.
 Corrective Actions: 1) Review current switch alerts for the affected switch.
                     2) Examine the monitoring status of the switch using the 'system switch ethernet show' command. If the switch is listed in the output, resolve the issue listed in the reason field, then attempt to restart the monitoring process using the 'system switch ethernet modify -device "IP_switch_A_1" -is-monitoring-enabled-admin true' command.
                     3) If the switch is not listed under the 'system switch ethernet show' command, investigate the cause of its absence. This could be due to the switch being disconnected, or because link discovery information via CDP or LLDP is not being received by ONTAP.
                     If the switch was not disconnected, start by confirming it is listed in the output of 'network device-discovery show'.
                     If the Ethernet switch is not listed, check that the
                     appropriate link discovery protocol is enabled.
