适用场景

  • 9.5P4之前的所有集群模式ONTAP 版本
  • 所有 SAN 主机 

问题描述

Data ONTAP 为存储器路径提供了三种ALUA状态:

  • 主动/优化(指向拥有LUN的节点)
  • 主动/非优化(到不拥有LUN的任何节点)
  • 正在过渡

只有在接管或交还期间、当路径从一个活动状态过渡到另一个活动状态时、才会短暂显示过渡状态。

在某些情况下、路径会停留在"正在过渡"状态、主机无法使用它们。

  • Windows 可能会在DSM中将路径状态报告为"正在过渡"。 
  • ESX 将报告IO错误和 sense data returned as 0x2 0x4 0xa。  
  • AIX 引发以下错误
    May 30 00:39:07 hdisk1 P SC_DISK_ERR2 path 0 TEST UNIT READY CHECK NOT READY; LOGICAL UNIT NOT ACCESSIBLE, ASYMMETRIC ACCESS STATE TRANSITION May 30 00:38:53 hdisk0 P SC_DISK_ERR2 path 10 TEST UNIT READY CHECK NOT READY; LOGICAL UNIT NOT ACCESSIBLE, ASYMMETRIC ACCESS STATE TRANSITION
