适用场景

  • ONTAP 9
  • FC SAN
  • Brocade 交换机上的端口
  • Brocade光纤操作系统(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对于适配器显示没有接收功率和正常发射功率:
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适配器上的 LIF 显示扩展状态Waiting for Link
cluster1::> network interface show -instance -curr-node cluster1-01 -curr-port 0a
[...]
Administrative Status: up
Extended Status: Waiting for Link.
  • EMS 日志中显示链接中断:

[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.

  • switchshow 在连接的 Brocade 交换机上显示No_Sync状态:
switch:admin> switchshow

  • sfpshow 开关显示接收和发射功率正常:
switch:admin> sfpshow 13
[...]
RX Power:   -0.3   dBm (933.5uW)
TX Power:   -0.6   dBm (862.3 uW)
  • 在交换机端,当将连接的线缆换到另一个端口时,问题会随着线缆一起出现。
  • 在 NetApp 端,当将线缆与连接到同一光纤网络/交换机的 HA 伙伴节点上适配器上已知正常工作的线缆交换时,问题也会随着线缆一起出现。
