问题描述

  • ONTAP 重新启动或升级后,具有基于 XL710 的 40 千兆以太网集群端口的节点会报告集群网络降级事件。

  • 示例:
  • [node1:vifmgr:vifmgr.cluscheck.hwerrors:alert]:节点 node1 上的端口 e8a 报告了大量(每 1000 个数据包至少 1 个)观察到的硬件错误(CRC、长度、对齐、丢弃)。

  • 40GbE 端口(用于集群或前端数据)在 ifstat 命令的 RECEIVE 部分报告 CRC 错误。

  • 接口 e8a(0 小时 5 分钟 31 秒)--
    收到
    总帧数:23634 | 帧/秒:71 | 总字节数:2019k
    字节/秒:6100 | 总错误数:18292 | 每分钟错误数:3316
    总丢弃次数:0 | 每分钟丢弃次数:0 | 多路/广播:92
    非主 u/c: 0 | CRC 错误: 16978 | 残帧: 0

  • 40GbE 端口链路可能会出现抖动或随后发生故障。
