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 配对 路径 配置不当 消息的 含义是什么?有关此错误消息的完整讨论。

问题说明

SAN通常提供多个路径来允许主机访问LUN。要最大程度地提高SAN的冗余度、主机操作系统必须使用多路径I/O (MPIO)软件。MPIO软件会监控所有可用路径、并为操作系统确定应使用的路径。NetApp目前支持两种适用于Solaris的MPIO软件:本机MPIO模块(MPxIO)和Veritas动态多路径(DMP)。以下过程概述了如何观察MPxIO和Veritas DMP配置。FCP Solaris Host Utilities中介绍了设置MPIO配置的步骤。
