有关集群网络已降级的频繁链路轻拍、请向主发出呼叫
适用场景
- ONTAP 9
- FAS/AFA系统
问题描述
- 集群端口链路发生闪烁、导致集群网络降级、系统报告以下事件：
[Node-02: intr: netif.linkDown:info]: Ethernet e0a: Link down, check cable.
[Node-02: vifmgr: vifmgr.portdown:notice]: A link down event was received on node Node-02, port e0a.
[Node-02: vifmgr: vifmgr.clus.linkdown:EMERGENCY]: The cluster port e0a on node Node-02 has gone down unexpectedly.
[Node-02: intr: netif.linkUp:info]: Ethernet e0a: Link up.
[Node-02: vifmgr: vifmgr.portup:notice]: A link up event was received on node Node-02, port e0a.
[Node-02: vifmgr: vifmgr.port.monitor.failed:error]: The "link_flapping" health check for port e0a (node Node-02) has failed. The port is operating in a degraded state.
[Node-02: vifmgr: callhome.clus.net.degraded:alert]: Call home for CLUSTER NETWORK DEGRADED: Frequent Link Flapping - Cluster port e0a on node Node-02 has experienced multiple link down notifications.
- 由于链路翻盖、集群端口已降级：
Cluster::*> network port show -health-status degraded -fields health-degraded-reasons
node port health-degraded-reasons
---------- ---- -----------------------
Node-02 e0a link_flapping
- 当 集群端口和集群交换机之间的链路关闭时、事件日志会报告以下警报：
[Node-01: cshmd: hm.alert.raised:alert]: Alert Id = ClusterSwitchConnectivity_Alert , Alerting Resource = Node-02 raised by monitor ethernet-switch
[Node-01: mgwd: callhome.hm.alert.major:alert]: Call home for Health Monitor process cshm: ClusterSwitchConnectivity_Alert[Node-02].
