适用场景

  • AFF/FAS 系统
  • Brocade 交换机

问题描述

  • 目标端口上未出现 FC 链路。
  • sysconfig -a 输出如下所示(以黄色突出显示)。

CLI 命令 - system node run -node <node name> -command sysconfig -a

示例:

slot 5: Fibre Channel Target Host Adapter 5b
         (Emulex LPe32000 (LPe32004) rev. 12, <LINK DISCONNECTED>)
         Board Name:     111-03648
         Serial Number:    FP01142277
         Firmware rev:    12.2.390.0
         Host Port Addr:   000000
         FC Nodename:     50:0a:09:80:80:23:6f:90 (500a098080236f90)
         FC Portname:     50:0a:09:82:80:23:6f:90 (500a098280236f90)
         Connection:     No link
         Switch Port:    Unknown
      SFP Vendor Name:   AVAGO
      SFP Vendor P/N:   AFBR-57G5MZ-ELX
      SFP Vendor Rev:   
      SFP Serial No.:   AD2003G02U1
      SFP Connector:    LC
      SFP Capabilities:  8, 16, 32 Gbit/Sec

  • 确保使用了受支持的 SFP ,并且可以从 NetApp Hardware Universe 验证此 SFP 。[1]
  • 在 EMS 日志中,观察到以下事件:

Thu Mar 04 16:41:01 +0000 [XXXXXXXX_01: fct_tpd_work_thread_0: scsitarget.slifct.linkBreak:error]: Link break detected on Fibre Channel target HBA 5b with event status 1 , topology type 1, status1 0x0, status2 0x0.
Thu Mar 04 16:41:01 +0000 [XXXXXXXX_01: nvmf_master_0: nvmf.spdk.err:debug]: fc_adm_api.c:2263 port link break: HW port 1 already offline. rc = 2 
Thu Mar 04 16:41:22 +0000 [XXXXXXXX_01: fct_tpd_work_thread_0: scsitarget.hwpfct.linkUp:notice]: Link up on Fibre Channel target adapter 5b.

  • 根据计划的布线示意图,的输出 portshow 表示所连接设备的 WWPN 与 sysconfig -a 输出中列出的 WWPN 不同:

示例:

sysconfig -a 输出:

slot 5: Fibre Channel Target Host Adapter 5b
         (Emulex LPe32000 (LPe32004) rev. 12, <LINK DISCONNECTED>)
         Board Name:     111-03648
         Serial Number:    FP01142277
         Firmware rev:    12.2.390.0
         Host Port Addr:   000000
         FC Nodename:     50:0a:09:80:80:23:6f:90 (500a098080236f90)
         FC Portname:    50:0a:09:82:80:23:6f:90 (500a098280236f90)
         Connection:     No link
         Switch Port:     Unknown
      SFP Vendor Name:   AVAGO
      SFP Vendor P/N:   AFBR-57G5MZ-ELX
      SFP Vendor Rev:   
      SFP Serial No.:   AD2003G02U1
      SFP Connector:    LC
      SFP Capabilities:  8, 16, 32 Gbit/Sec

portShow 输出:

  • 从上述示例中可以看出,目标端口 5b 的 WWPN 与交换机端口 19 上连接的设备的 WWPN 不同,这表示连接到交换机的设备不正确。
