适用于

  • ONTAP 9
  • Cluster Switches
  • VMware NFS Datastores

问题

  • 升级 ONTAP 和集群交换机后,当卷不是 NFS LIF 的本地卷时,NFS 数据存储变得无法访问。
  • 症状包括:
    • 受影响卷上的高延迟和零吞吐量
    • VMware 虚拟机断开连接或无法访问数据存储
    • 将 NFS LIF 迁移到其他节点暂时恢复了连接
    • 诊断分析显示,尽管 RCF 文件中存在,但集群交换机端口 49 和 50 未应用任何配置
    • 巨型帧(9000 MTU)在交换机间链路上不起作用
