适用场景

  • ONTAP 9
  • SnapMirror
  • 级联
  • 长期保留(LTR)快照/二级存储快照

问题描述

  • 级联拓扑中的SnapMirror关系失败、原因是:The source "svm:volume" is the destination of a SnapMirror relationship with policy "policy" which has Snapshot copy creation schedules. Cascading is not supported for this configuration.
  • 长期保留(LTR)快照配置在A->B->C SnapMirror级联中的"B"卷上、或在较大级联中的另一个中间SnapMirror目标卷上。
  • LTR快照由应用于SnapMirror策略规则的计划定义。此规则不会从源卷复制Snapshot、而是直接在目标卷上创建Snapshot。有关详细信息、请参见 ONTAP 9 SnapMirror策略规则中的"SCHEDUE"参数如何工作?
  • 由于发现此配置存在问题、ONTAP已开始阻止此配置
  • 从未阻止不受支持的配置的ONTAP版本升级到阻止不受支持的配置的ONTAP版本后、可能会开始看到此错误。
  • 阻止不受支持的配置的ONTAP版本:
    • 9.10.1 P18.
    • 9.11.1P15.
    • 9.12.1P12.
    • 9.13.1P9.
    • 9.14.1P2.
    • 未来版本
