问题描述

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

::> network interface show -data-protocol fcp Logical Status Network Current Current Is Vserver Interface Admin/Oper Address/Mask Node Port Home ----------- ---------- ---------- ------------------ ------------- ------- ---- vs1 lif up/down 20:xx:xx:xx:xx:xx:xx:xx nodename 10c true ::> network interface show -data-protocol fcp -fields status-admin,status-oper,status-extended vserver lif status-oper status-extended status-admin ----------- ------------------ ----------- ----------------- ------------ vs1 lif down Waiting for Link. up

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

::> network fcp adapter show Connection Port Admin Operational Node Adapter Established Address Status Status ------------ ------- ----------- --------- ------- ----------------------- node 10c true 0 up link disconnected

报告目标适配器中的SFP无信号电源且超出范围

::> fcp adapter show -instance -node node -adapter 10c [...] Received Optical Power: 0 (uWatts) Is Received Power In Range: false SFP Transmitted Optical Power: 0 (uWatts) Is Xmit Power In Range: false [...]
