适用场景

  • 无交换机集群
  • FAS8040

问题描述

  • 接收有关的警报 CLUSTER NETWORK DEGRADED
  • EMS日志显示以下消息
 
callhome.clus.net.degraded: Call home for CLUSTER NETWORK DEGRADED: Total Packet Loss - Ping failures detected between Node-02_clus1 ( 169.254.85.22 ) on Node-02 and Node-01_clus1 ( 169.254.135.15 ) on Node-01
  • cluster show会将集群中两个节点的运行状况显示为false
Cluster::> cluster show
Node                  Health  Eligibility
--------------------- ------- ------------
Node-01         false  true
Node-02         false  true
2 entries were displayed.
  • 数据聚合可能已脱机

Cluster::> storage aggregate show

Info: Node Node-01 that hosts aggregate aggr_sas_01 is offline
      Node Node-01 that hosts aggregate aggr_sas_03 is offline
      Node Node-01 that hosts aggregate aggr_sata_01 is offline
      Node Node-01 that hosts aggregate aggr_Node_01_root is offline

  • 将Ping失败的主端口中的集群LUN迁移到故障转移目标、聚合将恢复联机并恢复集群运行状况
  • 已更换Ping失败的集群主端口与问题描述之间的缆线、但此缆线仍存在
