问题描述

  • 在将具有存储效率(LRSE)的 SnapMirror 逻辑复制到 LRSE 级联期间,ONTAP 可能会触发意外的 SnapMirror 数据仓库重建
    示例:
    • 卷 A 和卷 B 之间的异步 SnapMirror,然后是从卷 B 到卷 C 的异步 SnapMirror
    • 在数据仓库重建处于活动状态时,卷 B 和卷 C 之间的传输状态保持在"Preparing"
    • 因此,传输需要比平时更长的时间才能完成,这可能会影响恢复点目标 (RPO)
  • 不会对 SnapMirror 关系的功能产生其他影响,也不会对级联中涉及的任何卷的数据完整性和可用性产生其他影响
