适用场景

  • ONTAP 9.11.1RC1
  • ONTAP 9.11.1
  • 与ONTAP 9.11.1集群建立对等关系的ONTAP 集群(任何兼容版本)
  • 集群间SnapMirror关系

问题描述

  • 升级到ONTAP 9.11.1RC1或9.11.1后、集群对等关系将失败、主要影响集群间SnapMirror
  • 受影响的SnapMirror关系可能会与错误或症状相关联、包括:

Failed to create Snapshot copy

CSM: Connection aborted

无法传输数据(Transferring   0B)

  • 受影响的集群对等关系会持续报告 Partial、或者会间歇性地从 Partial 状态变为 Available 状态
    • 用于 cluster peer show 查看集群对等关系的状态
    • 比较 cluster peer show 多次输出迭代、以检测从 部分可用的摆动情况

示例:

CLUSTER-02::> cluster peer show -instance

            Peer Cluster Name: CLUSTER-01
      Remote Intercluster Addresses: 10.37.22.200, 10.37.22.205
    Availability of the Remote Cluster: Partial
           Remote Cluster Name: CLUSTER-01

CLUSTER-02::> cluster peer show -instance

            Peer Cluster Name: CLUSTER-01
      Remote Intercluster Addresses: 10.37.22.200, 10.37.22.205
    Availability of the Remote Cluster: Available
           Remote Cluster Name: CLUSTER-01

  • 受影响的集群对等关系可能仍处于 部分 状态、而不是处于"可用"状态

示例:

CLUSTER-02::> cluster peer show -instance

            Peer Cluster Name: CLUSTER-01
      Remote Intercluster Addresses: 10.37.22.200, 10.37.22.205
    Availability of the Remote Cluster: Partial
           Remote Cluster Name: CLUSTER-01

CLUSTER-02::> cluster peer show -instance

            Peer Cluster Name: CLUSTER-01
      Remote Intercluster Addresses: 10.37.22.200, 10.37.22.205
    Availability of the Remote Cluster: Partial
           Remote Cluster Name: CLUSTER-01

  • 集群对等不稳定可能会影响使用集群对等连接交换API调用或数据的任何操作

注意: 本文中介绍的问题描述 仅适用于 适用场景 ONTAP 9.11.1RC1、9.11.1或与ONTAP 9.11.1/9.11.1RC1建立对等关系的其他ONTAP 版本。
