适用场景

  • Data ONTAP 8 7-模式
  • FlexPod
  • Data ONTAP 7 及更早版本

问题描述

系统日志和 EMS 消息:

[hostname: scsitarget.partnerPath.misconfigured:error]: FCP Partner Path Misconfigured.
[hostname: scsitarget.partnerPath.misconfigured:error]: FCP Partner Path Misconfigured - Host I/O access through a non-primary and non-optimal path was detected. 

请参见文章《 FCP 合作伙伴路径配置错误的消息意味着什么? 有关此错误消息的完整讨论。

问题说明

SAN 通常提供多条路径以允许主机访问 LUN 。要最大化 SAN 的冗余性、主机操作系统必须使用多路径 I/O ( MPIO )软件。MPIO 软件将监控所有可用路径并决定应使用哪个路径。NetApp 目前支持两种形式的 MPIO 软件用于 Solaris 、本机 MPIO 模块 (MPXIO) 和 Veritas Dynamic Multipathing (DMP) 。以下过程概述了如何观察 MPXIO 和 Veritas DMP 配置。FCP Solaris 主机实用程序中介绍了设置 MPIO 配置的步骤。
