问题描述

检查Active IQ是否会影响您的系统

通用SAS 和ACP 布线指南 为可靠性、通用性和通用性制定了多条布线规则。其中一条规则是、在从单个节点到单个磁盘存储堆栈的两条路径中、一条路径应连接到存储堆栈的顶部、另一条路径应连接到存储堆栈的底部。

如果MyAutoSupport或其他来源通知您违反了此特定规则、本文将介绍如何诊断问题描述并可能进行修复、而不会造成停机。

注意: 此处记录的过程仅在 Data ONTAP 8.2.1,8.3及更高版本中经过测试并证明是稳定的。在早期版本的Data ONTAP上尝试此操作可能会导致计划外系统停机。有关详细信息,请参见错误 691240中的指导
