FC目标适配器链路未连接
适用场景
- ONTAP 9
- FC SAN
- Brocade 交换机上的端口
- Brocade Fabric OS (FOS)
问题描述
SYCONFIG-A
显示适配器状态为LINK NOT CONNECTED
:
slot 1: Fibre Channel Target Host Adapter 1c
(Emulex LPe32000 (LPe32004) rev. 12, <LINK NOT CONNECTED>)
FCP-ADAPTER.XML
或者network fcp adapter show
,适配器显示 运行状态LINK NOT CONNECTED
:
cluster1::> network fcp adapter show -node cluster1-01 -adapter 0a
[...]
Administrative Status: up
Operational Status: link not connected
Extended Status: ADAPTER UP
FCP-ADAPTER.XML
或者network fcp adapter show
、对于适配器、显示未接通 电源和正常传输电源:
cluster1::> network fcp adapter show -node cluster1-01 -adapter 0a
[...]
Received Optical Power: 0.0 (uWatts)
Is Received Power In Range: false
SFP Transmitted Optical Power: 1069.1 (uWatts)
Is Xmit Power In Range: true
NETWORK-INTERFACE.XML
或者network interface show
,对于适配器上的Waiting for Link
“扩展”状态:
cluster1::> network interface show -instance -curr-node cluster1-01 -curr-port 0a
[...]
Administrative Status: up
Extended Status: Waiting for Link.
- EMS日志中显示的链路中断:
[cluster1-01: fct_tpd_work_thread_0: scsitarget.slifct.linkBreak:error]: Link break detected on Fibre Channel target HBA 0a with event status 1 , topology type 1, status1 0x0, status2 0x0.

- 在交换机端、 将连接的缆线交换到另一个端口后、问题描述会随缆线一起传输。
- 在NetApp端、如果使用 HA配对节点上连接到同一网络结构/交换机的适配器上已知正常工作的缆线交换此缆线、则问题描述会随缆线一起传输。
