适用场景

  • ONTAP 9
  • SnapMirror业务连续性(SM-BC)
  • SnapMirror 活动同步 

问题描述

  • SnapMirror故障转移启动在一周前完成、但未发生故障转移、并且在尝试故障转移后一周仍会将源LUN写入
  • 复制已成功故障转移到灾难恢复站点、但SAN主机仍会连接到源站点LUN
  • 现在、所有报告为"同步中"的SM-BC镜像都以原始源作为目标
  • 现在、源卷的类型为DP、灾难恢复卷的类型为RW
  • 然后、客户取消映射原始源上的LUN、客户端将失去与这些LUN的连接、直到重新映射源LUN为止

警告

使用Windows Server主机映射时、不要进行故障转移、也不要从备用阵列中删除SM-AS关系/一致性组。这将导致Microsoft MPIO损坏。
