ONTAP重新启动后、XL710 40GbE端口上出现CRC错误
适用场景
- ONTAP 9
- 10/40千兆以太网控制器XL710网络端口
- X91440A 以太网模块
- X1144A 以太网网卡 (PCIe)
- AFF A700s板载以太网端口
- 前端 40G 交换机，例如 Cisco Nexus 或类似产品
问题描述
- 存储系统具有连接到 40G 交换机（例如 Cisco Nexus 9336C-FX2）的 10/40 千兆以太网控制器 XL710 网络端口。
- 在 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: callhome.clus.net.degraded:alert]: Call home for CLUSTER NETWORK DEGRADED: CRC Errors Detected - High CRC errors detected on port e8a node node1
[node1: vifmgr: vifmgr.cluscheck.hwerrors:alert]: Port e8a on node node1 is reporting a high number (at least 1 per 1000 packets) of observed hardware errors (CRC, length, alignment, dropped).- 40GbE 端口（用于集群或前端数据）在接收部分报告 CRC 错误
ifstat命令。示例：
::>system node run -node <node_name> -command ifstat e8a
-- interface e8a (0 hours, 5 minutes, 31 seconds) --
