适用场景

  • Brocade FC 交换机
  • ONTAP 9

问题描述

  • 同一网络结构中的两个交换机的CRC错误越来越多
  • 交换机1在连接到FC目标适配器的F端口上的crc_errcrc_g_eof 增加:
switchshow     :
[...]
Index Port Address  Media Speed  State    Proto
==================================================
  16  16  011000  id   N16   Online    FC  F-Port  1 N Port + 1 NPIV public 
 
porterrshow     :
      frames     enc   crc   crc  
     tx    rx    in   err   g_eof 
  16:   1.6g   3.1g   0    3.1k  3.0k 
  • 连接到交换机端口的FC目标适配器出现EMS IO错误 :
[BAFF-A-01: fct_tpd_work_thread_0: fcp.io.status:debug]: STIO Adapter:1c IO WQE failure, Handle 0x1, Type 8, S_ID: 10100, VPI: 259, OX_ID: 2BF, Status 0x3 Ext_Status 0x16
[BAFF-A-01: fct_tpd_work_thread_0: fcp.io.status:debug]: STIO Adapter:1c IO WQE failure, Handle 0x1, Type 8, S_ID: 11200, VPI: 259, OX_ID: 154, Status 0x3 Ext_Status 0x16
[BAFF-A-01: fct_tpd_work_thread_0: fcp.io.status:debug]: STIO Adapter:1c IO WQE failure, Handle 0x1, Type 8, S_ID: 10200, VPI: 259, OX_ID: 55F, Status 0x3 Ext_Status 0x16
  • 交换机2在E端口上的crc_err 增加:
switchshow     :
[...]
Index Port Address  Media Speed  State    Proto
==================================================
  23  23  021700  id   16G   Online    FC  E-Port  10:00:88:94:71:12:34:56 "switch1" (downstream)(Trunk master)  
 
porterrshow     :
      frames     enc   crc   crc  
     tx    rx    in   err   g_eof 
  23:   3.2g   3.6g   0    1.1k  0   
  • 所有端口上的SFP发送和接收功率均正常
  •   首先调查增加crc_errcrc_g_eof链路
    • 将缆线移至交换机上的其他端口和SFP后、错误仍会增加
    • 更换电缆后、错误仍会增加
    • 重新拔插连接的设备 SFP后、错误仍会增加
