适用场景

  •  Data ONTAP 7 及更早版本 
  •  Data ONTAP 8 7-模式 
  •  DSM for Windows MPIO 
  •  FlexPod

问题描述

本文档讨论如何使用两种形式的 DSM 查看 MPIO 配置和状态。

  • 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确定操作系统应使用的路径。
  • Microsoft MPIO 系统将使用 DSM 自动配置。
  • 它使用与存储集群的带内通信来确定主路径和次路径。

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.

有关此错误消息的完整讨论、请参见文章《 FCP 合作伙伴路径配置错误消息的含义是什么?

Terminology

  • 合作伙伴路径:使用伙伴节点访问由本地节点托管的 LUN 的任何路径。LUN 位于主动 - 主动群集中。
  • 非主路径:与伙伴路径、代理路径和辅助路径同义。所有这些都是非主路径的示例。
  • FCP 目标端口:向主机提供 FCP 服务的光纤通道接口。
  • 虚拟目标互连( Vtic ):启动程序组列表中显示的虚拟 FCP 目标接口。Vtic 用于指示启动程序有权访问辅助路径。
