FC链路已关闭

• ONTAP 9
• Cisco MDS 9148S

• Cisco MDS交换机上连接的FC端口已关闭、启用后大约会在一分钟后关闭
• 已验证交换机端SFP和存储控制器目标适配器端口SFP中的缆线是否正确连接
• LIF的网络接口状态为admin up、operdown和status-Extended Waiting for link

注意：也可以使用 network interface show -data-protocol fcp -fields status-admin,status-oper,status-extended,curr-port

• 确认物理端口状态
