适用于

  • ONTAP 9
  • SnapMirror
  • 存储虚拟机灾难恢复 (SVM DR)
  • SnapMirror 主动同步(以前称为SnapMirror业务连续性,SM-BC) 

问题解答

  • 基线快照不会在任何时候自动滚动
    • 反向重新同步
    • 当关系回到其原始方向时
    • 新配置关系的首次同步
  • 旧基线快照必须由存储管理员清理(手动删除)
  • 这是正常和预期的 SnapMirror/快照行为
  • 这是为了防止在角色反转步骤中删除任何基线快照,这将阻止后续更新/重新同步,并需要整个基线传输来重新建立 SnapMirror
  • 不再需要快照后,请参阅 如何识别和删除不需要的SnapMirror快照 有关如何识别和删除这些快照的信息
