问题描述

节点上的一个FC端口已关闭：

slot 1: FC Host Adapter 1c (Emulex XE201 rev. 48, <DOWN>)

Board name: 111-02455

Serial Number: FCXXXXXX77

Firmware rev: 11.4.277.0

Host Port Id: N/A

FC Node Name: 2:000:00109b:25b9bc

FC Port Name: 1:000:00109b:25b9bc

SFP Vendor: AVAGO

SFP Part Number: AFBR-57F5MZ-NA1

SFP Serial Number: AA1XXXXX1RD

SFP Capabilities: 4, 8 or 16 Gbit

Link Data Rate: N/A

连接到上述节点端口的ATto网桥FC端口也已关闭、并且网桥报告以下错误：

ATTO_161.XXX.XX.XXX(200000XXXXXXXXX):FC_PORT_1 is Offline.

受影响节点将转换为"混合路径"配置：

NetApp Release 9.3P7: Wed Jul 25 06:16:06 EDT 2018

System ID: 0538031811 (Node-01)

System Serial Number: 45XXXXXXXX8 (Node-01)

System Rev: A4

System Storage Configuration: Mixed-Path

StorageBridgePortDown_Alert 和 FC-AL LINK_FAILURE 事件日志中报告的警报：

尽管更换了SFP和缆线、节点上受影响的FC端口与ATto网桥之间的链路仍会关闭。
在已知良好的节点端口和受影响的ATto之间交换缆线后、ATto网桥上的链路联机。
