适用场景

  • ONTAP 9
  • 光纤连接MetroCluster

问题描述

  • Fabric MetroCluster系统的事件日志中报告了以下错误:

[Node-01: slifc_intrd: fci.link.break:error]: Link break detected on Fibre Channel adapter 3c.
[Node-01: lhm_main: callhome.fc.al.link:alert]: Call home for FC-AL LINK_FAILURE (3c)  

  • 受影响的FC端口上没有链路:

   slot 3: FC Host Adapter 3c (Emulex XE501 rev. 1, <DOWN>)
      Board name:     111-03648
      Serial Number:    FCXXXXX993
      Firmware rev:    11.4.277.0
      Host Port Id:    N/A
      FC Node Name:    2:000:00109b:4f18e1
      FC Port Name:    1:000:00109b:4f18e1
      SFP Vendor:     FINISAR CORP.
      SFP Part Number:   FTLF8532P4BCV-EM
      SFP Serial Number: PZXXXXX
      SFP Capabilities:  8, 16 or 32 Gbit
      Link Data Rate:   N/A 

  • 受影响的节点将从"四路径"配置过渡到"多路径"配置。
  • 交换机日志指示交换机端口因多个链路故障而被禁用:

Index Port Address  Media Speed   State     Proto
==================================================
  5   5   080500   id   16G    No_Light   FC  (Ports on Demand license not assigned or reserved yet)
  6  6   080600   id   32G    Port_Flt  FC  Disabled

   
2024/10/30-07:44:23, [PORT-1003], 10881, FID 128, WARNING, fxzz-fdr-sansw24, Port 6 Faulted because of many Link Failures.
2024/10/30-07:50:25, [PORT-1003], 10882, FID 128, WARNING, fxzz-fdr-sansw24, Port 6 Faulted because of many Link Failures.   

  • 更换 交换机端口和节点端口上的SFP/Cable不能解决问题描述问题。
  • 将缆线从受影响的FC端口交换到节点上的其他可用端口后、链路恢复正常。
