适用场景

  • ONTAP 9.x
  • SnapMirror
  • 集群对等

问题解答

  • cluster peer pingcluster peer health show 是显示当前状态的工具 
  • 此错误可能表示网络问题描述 为非持久网络、数据包跟踪可揭示有关网络运行状况的更多详细信息
    • 网络问题描述 的一个示例是、较旧的交换机硬件可能无法处理来自NetApp集群间的默认流量
    • 如果尚未更换旧设备或无法更换旧设备、设置SnapMirror全局复制限制可能有助于解决过度饱和链路问题
  • 备注:数据包跟踪应捕获cpeer.unavailable:alert 来自源集群和目标集群的消息实例,以便于进行故障排除
