在光纤通道适配器上检测到链路断开

适用于

• MetroCluster
• ONTAP 9
• SAN
• FCP

问题

1. Fibre Channel 主机适配器离线或抖动。
2. 确定  正常范围 中的 SFP
3. 在交换机上隔离源的步骤包括以下内容：
   • 查看交换机日志，确认问题已隔离到单个连接
   • 收集"supportshow"交换机日志。
     • 检查"porterrshow"以确认交换机在关联端口上看到错误
     • 检查"sfpshow -all'"以获取端口硬件详细信息
     • 查看电源 RX 和 TX 读数是否有异常
4. 更换或重新拔插 SFP 交换机和存储端。
5. 如果在交换机/NetApp 上未发现明显故障，请检查是否有任何涉及潜在硬件问题的配线面板
