  • FCP

问题描述

  • 事件日志条目指示FC链路已断开:

5/23/2020 21:11:31  cluster-node1  ERROR scsitarget.ispfct.linkBreak: Link break detected on Fibre Channel target adapter 1b. Firmware status code status1 0x2, status2 0x7, and status4 0x0.

 

  • sysconfg -a 将端口状态报告为""Link Disconnected
slot 1: Fibre Channel Target Host Adapter 1b (QLogic 8324 (8362) rev. 2, <LINK DISCONNECTED>) Board Name: QLE2672 Serial Number: RFE2005W04482 Firmware rev: 8.9.0 Flash rev: 1.1.2 Host Port Addr: 000000 FC Nodename: xx:0a:09:80:80:xx:xy:xx (500a098080b3a125) FC Portname: xx:0a:09:82:80:xy:yy:xx (500a098280b3a125) Connection: No link Switch Port: Unknown SFP Vendor Name: FINISAR CORP. SFP Vendor P/N: FTLF8529P4BCV-QM SFP Vendor Rev: B SFP Serial No.: P2SABCS SFP Connector: LC

 

  • Network fcp adapter show 在命令行界面上执行的命令会将运行状态报告为"link disconnected"

cluster::> network fcp adapter show

  • 存储HBA端口仍处于物理连接状态

 

尝试隔离问题描述的以下故障诊断步骤:

  • 已 使用以下命令验证远程SFP的运行状况并已退回端口:

Cisco示例:

switch# config terminal
switch(config)# interface fc <slot>/<port#>
switch(config)# show int fc <slot>/<port#> transceiver detail
switch(config-if)# shutdown
switch(config-if)# no shutdown

Brocade示例:

switch:admin> sfpshow <index # OR slot/port #>
switch:admin> portdisable <index # OR slot/port #>
switch:admin> portenable <index # OR slot/port #>

  • 已执行物理检查并重新安装连杆和 配线板部件。
  • 重新安装后、重复端口弹跳过程。
  • 更换/交换两端的组件、包括缆线和SFP。
