适用场景

  • ONTAP 9
  • FCP

问题描述

  • FC目标端口链路—不稳定。
  • EMS NetApp上会记录以下事件:
[?] Wed Oct 14 09:22:49 MDT [host1: fct_tpd_work_thread_0: scsitarget.slifct.linkBreak:error]: Link break detected on Fibre Channel target HBA 4c with event status 1 , topology type 1, status1 0x0, status2 0x0.
[?] Wed Oct 14 09:22:50 MDT [host1: fct_tpd_work_thread_0: scsitarget.hwpfct.linkUp:notice]: Link up on Fibre Channel target adapter 4c.
 
Tue Mar 05 15:19:28 0530 [NetApp: fct_tpd_work_thread_0: scsitarget.slifct.wqeError:debug]: FC port 3a has a WQE processing failure of type SLI_ELS_REQ, command PLOGI, subtype x0, with status of 3 and an extended status x4 for NPIV port 0. 
Tue Mar 05 15:19:29 0530 [NetApp: fct_tpd_work_thread_0: scsitarget.slifct.wqeError:debug]: FC port 3a has a WQE processing failure of type SLI_ELS_REQ, command PLOGI, subtype x0, with status of 3 and an extended status x1a for NPIV port 0.
Tue Mar 05 15:26:48 0530 [NetApp: fct_tpd_work_thread_0: scsitarget.slifct.linkBreak:error]: Link break detected on Fibre Channel target HBA 3a with event status 1 , topology type 1, status1 0x0, status2 0x0. 
Tue Mar 05 15:26:59 0530 [NetApp: fct_tpd_work_thread_0: scsitarget.slifct.wqeError:debug]: FC port 3a has a WQE processing failure of type SLI_ELS_REQ, command PLOGI, subtype x0, with status of 3 and an extended status x1a for NPIV port 0."
  • 可以执行以下步骤来隔离问题描述:
    • 检查控制器端口状态、如果Tx 信号 功率低、请更换SFP。
    • 检查已连接交换机端口的SFP状态、如果交换机端口Tx 电源低、请更换SFP。
    • 如果  两个FC端的SFP Tx功率均正常、但 任一端的SFP Rx功率均较低、请更换FC缆线。
    • 如果涉及配线板、请对链路组件进行故障排除。
    • 如果两端的Rx信号均较低、请 检查两者之间是否存在配线板、并尝试使用其他端口进行测试
