适用场景

  • ONTAP 9
  • 集群对等方

问题描述

  • 如果远程集群的接口不可用、 cluster peer health 则会报告错误、EMS以及输出中的更改。
  • 例如、以下输出指示中的某些节点 cluster1 无法从访问 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.

  • 如果您尝试 通过System Manager (GUI)创建保护关系、则 在选择目标集群时会显示以下警告:

Cluster peering status is unhealthy.

  • cpeer.unavailable 每当远程集群不可用时、系统也会报告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.

  • 当它再次可用时、不会报告任何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。
    • 每 cpeer.unavailable 条消息之间都会隐式过渡到可用状态。
