交换机重新启动后， ASUP 中会显示集群网络降级警报
适用场景
- CN1610集群交换机
- ONTAP 9
- FAS/AFF
问题描述
- CN1610交换机在断电或维护后重新启动。
- NetApp系统
CLUSTER NETWORK DEGRADED会在事件日志中报告以下警报：
[Node-01: vifmgr: callhome.clus.net.degraded:alert]: Call home for CLUSTER NETWORK DEGRADED: Total Packet Loss - Ping failures detected between Node-01_clus2 ( 169.XXX.XX.XXX ) on Node-01 and Node-04_clus1 ( 169.XXX.XX.XXX ) on Node-04
- 如果使用ISL LAG (链路聚合)、您可能会看到此ASUP警报：
(Health Monitor process cshm: SwitchIfIslDownWarn_Alert[<switch_name>/<LAG_name>]) ALERT - 在事件日志中：
[Node-04: cshmd: hm.alert.raised:alert]: Alert Id = SwitchIfIslDownWarn_Alert , Alerting Resource = cluster-sw1/ Link Aggregate 1 raised by monitor cluster-switch
- 交换机运行状况已降级：
