适用于

  • ONTAP 9
  • EMS
  • maxCID

问题描述

此时将显示以下 EMS 消息:
maxCID.threshold.exceeded or maxCID.limit.exceeded

  • 当集群中指示的节点接近其可以支持的活动/开放网络连接的最大数量时,就会发生事件 maxCID.threshold.exceeded
    • 在此情况下,客户端和/或应用程序即将遇到服务中断。
  • 事件 maxCID.limit.exceeded 在集群中指示的节点超过其可以支持的最大活动/开放网络连接数时发生。 
    • 在此情况下,客户端和/或应用程序很可能会遇到服务中断。

注: 

  • 在物理内存 <= 15 GB 的系统中,限制实际上是 10,000(加上内部连接的 10%),因此此限制是真正的通知。
    • 只有 Cloud Volumes ONTAP、 Amazon FSx for NetApp ONTAP 和 ONTAP Select 系统 具有如此小的内存。
  • 在物理内存 > 15 GB 的系统中,限制实际上是 100,000(加上内部连接的 10%),因此该限制实际上是错误的通知。 
  • 请查看追加信息有关如何计算可用和使用中 CID 数量的信息。
