状态信息

适用场景

  • ONTAP 9
  • FAS/AFF 系统
  • 在单个端口上报告 CRC 错误

问题描述

  • 报告端口所属的一个物理端口和 / 或 ifgroup 上的 CRC 错误的 EMS 消息:

4/16/2021 13:07:49  node_name ALERT vifmgr.cluscheck.crcerrors: Port a0b on node node_name is reporting a high number of observed hardware errors, possibly CRC errors.
4/16/2021 13:07:49  node_name ALERT vifmgr.cluscheck.crcerrors: Port e0d on node node_name is reporting a high number of observed hardware errors, possibly CRC errors.

  • ifstat 输出。示例:
