适用场景

  • ONTAP 9
  • 创建集群对等关系

问题描述

如果远程集群的接口不可用 cluster peer health ,则会报告输出中的错误, EMS 和更改。

  • 例如,以下输出表示中的某些节点 cluster1 无法访问 cluster2


cluster2::> cluster peer health show
Node     Cluster-Name          Node-Name
       Ping-Status         RDB-Health Cluster-Health Availability
---------- --------------------------- --------- --------------- -----------
  
node1
      cluster1               node1
       Data: unreachable
       ICMP: unreachable      true    true       false
                    node2
       Data: interface_reachable
       ICMP: interface_reachable true    true       true
node2
      cluster1               node1
       Data: unreachable
       ICMP: unreachable      true    true       false
                    node2
       Data: unreachable
       ICMP: unreachable      true    true       false
4 entries were displayed.

  • cpeer.unavailable 每次远程集群不可用时,也会报告 EMS 消息


cluster2::> event log show -messagename cpeer.unavailable -instance
  
      Node: node1
    Sequence#: 71687
      Time: 5/15/2012 14:02:37 
 
    Severity: ALERT
     Source: mgwd
  Message Name: cpeer.unavailable
      Event: cpeer.unavailable: Peer cluster cluster1 is no longer available.

  • 当它重新可用时,不会报告 EMS 消息。
    • 每当远程集群从 " 可用 " 过渡到 " 不可用 " 时,都会收到一条消息。
    • cpeer.unavailable 条消息之间都会隐式过渡到 Available 。
