适用场景

  • ONTAP 9 及更高版本
  • ONTAP 8.3

问题解答

  • 在目标集群中、使用 SnapMirror show命令和-snapshot-checkpoint参数查看基线传输和重新启动检查点的状态。

示例

cluster2::> snapmirror show -destination-path dest_vserver:vol3 -fields snapshot-checkpoint source-path destination-path snapshot-checkpoint -------------------- ---------------- ------------------- src_system:vol3 dest_vserver:vol3 50MB
  • 如果存在SnapMirror检查点、请使用 SnapMirror initialize命令恢复基线传输。

示例

cluster2::> snapmirror initialize -destination-path dest_vserver:vol3

但是,有时可以根据以下标准之一删除可重新启动的检查点

  1. 卷标记为脱机并通过任何方式删除时。
  2. 如果SnapMirror break' 对关系发出"命令。
  3. 如果发出带有硬中止开关的SnapMirror。执行硬中止将删除检查点。

如果重新启动检查点被删除,则重新启动传输将从开始开始而不是从检查点开始。
