适用于

  • MetroCluster
  • Data ONTAP 8 7-模式

问题描述

有关 ONTAP 9 的过程,请参见 MetroCluster 管理和灾难恢复的测试或维护切换一节

 

本文介绍在不希望在灾难时执行集群故障转移( CFOD - 即cf takeover -d)的情况下,在 7- 模式 MetroCluster 上执行计划内站点维护时应遵循的过程,以及使聚合联机所涉及的所有恢复 / 清理步骤。

注意:如果您考虑执行 CFOD 进行站点维护、请在执行此操作之前与 NetApp 技术支持联系。

以下是使用 MetroCluster 故障转移方法与执行 CFOD 的优势:

  • 使 MetroCluster 用户可以在不对 MetroCluster 执行 CFOD 的情况下将整个站点停机进行计划维护
  • 不需要任何停机时间
  • 消除了与完全 CFOD 相关的大多数风险和时间
     
要执行这些操作,需要对所有聚合进行镜像。
