适用场景

  • ONTAP 9
  • FCP
  • Brocade和Cisco SAN交换机

问题描述

  • 事件日志条目表示FC链路已断开连接:

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

  • 对于 FCP-Adapter.xmlASUP中的光纤通道目标适配器 日志、Rx和Tx功率显示为0.0 (uWatts)

Rx : 0.0 (uWatts)
Tx : 0.0 (uWatts)

  • Rx和Tx电源在存储和交换机端的任何一端都是最佳的。

port 9a
Rx : 623.0 (uWatts)
Tx : 1020.9 (uWatts)

Slot  9/Port  2:
RX Power:   -0.5   dBm (883.9uW) 
TX Power:   -1.6   dBm (697.3 uW) 

 

  • 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
           Connection  Port    Admin   Operational
Node      Adapter Established Address   Status  Status
------------ ------- ----------- --------- ------- -----------------------
cluster-node1
       0c    false     0      up    link not connected
cluster-node1
       0d    false     0      up    link not connected
cluster-node1
       1a      true     f0500    up    online
cluster-node1
       1b    true     0      up    link disconnected
cluster-node2
       0c    false     0      up    link not connected
cluster-node2
       0d    false     0      up    link not connected
cluster-node2
       1a    true     f0600    up      online
cluster-node2
       1b    true     f0600    up    online

  • 存储HBA端口仍以物理方式连接
  • 可以验证以下故障排除步骤以隔离问题描述:
    1. 使用以下命令验证远程SFP运行状况并退回端口:

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 #>

  1. 执行 物理检查并重新安装连杆和 配线板组件。
  2. 重新安装后、重复端口弹跳过程。
  3. 更换/交换两端的组件、包括缆线和SFP。
