在单个 NIC 端口上收到 CRC 错误
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
- 事件日志报告物理和/或逻辑端口上的硬件错误。
[node-01: vifmgr: vifmgr.cluscheck.crcerrors]: Port a0b on node node-01 is reporting a high number of observed hardware errors, possibly CRC errors
[node-02: vifmgr: vifmgr.cluscheck.crcerrors]: Port e0d on node node-02 is reporting a high number of observed hardware errors, possibly CRC errors
[node-02: vifmgr: vifmgr.cluscheck.hwerrors:alert]: Port e0d on node node-02 is reporting a high number (at least 1 per 1000 packets) of observed hardware errors (CRC, length, alignment, dropped)
[node-02: vifmgr: callhome.clus.net.degraded:alert]: Call home for CLUSTER NETWORK DEGRADED: CRC Errors Detected - High CRC errors detected on port e0d node node-02
ifstat如果ONTAP 收到错误、则输出将显示CRC错误。- 重新安装缆线/SFP后、问题描述 仍然存在、
ifstat -z并且位于受影响的节点上。
