适用场景

  • ONTAP 9
  • SnapMirror
  • ONTAP系统管理器

问题解答

  • 从系统管理器中取消SnapMirror传输时、将显示"保留所有部分传输的数据(可选)"复选框。
  • 此选项用于确定是否保留在当前SnapMirror操作期间已部分传输的数据。
  • 这等效于命令 snapmirror abort-hard 选项 。

详细信息行为:

  • 复选框选中:保留部分传输的数据、下次SnapMirror传输将从最后一个检查点恢复。
  • 与命令等效: snapmirror abort -destination-path <destination-path>

示例:如果传输以17.38 KB中止,则下次传输将从此检查点恢复。

::> snapmirror abort -destination-path cluster3_svm1:cluster3_svm1_projects
Operation is queued: snapmirror abort for the relationship with destination "cluster3_svm1:cluster3_svm1_projects".

::> snapmirror show -destination-path cluster3_svm1:cluster3_svm1_projects  -fields snapshot-checkpoint
source-path              destination-path           snapshot-checkpoint
------------------------------------ ------------------------------------ -------------------
cluster2_svm1:cluster2_svm1_projects cluster3_svm1:cluster3_svm1_projects 17.38KB 

::> snapmirror show
                                                     Progress
Source       Destination Mirror  Relationship   Total        Last
Path     Type  Path     State   Status      Progress  Healthy Updated
----------- ---- ------------ ------- -------------- --------- ------- --------

            XDP  cluster3_svm1:cluster3_svm1_projects
                         Snapmirrored
                               Transferring   17.38KB 

  • 未选中此框:丢弃部分传输的数据、下次SnapMirror传输将从头开始、并创建新快照。
  • 与命令等效: snapmirror abort -destination-path <destination-path> -hard true

示例:如果传输被中止,下一个传输将从0B开始。

::> snapmirror abort -destination-path cluster3_svm1:cluster3_svm1_projects -hard true 
Operation is queued: snapmirror abort for the relationship with destination "cluster3_svm1:cluster3_svm1_projects".

::> snapmirror show -destination-path cluster3_svm1:cluster3_svm1_projects  -fields snapshot-checkpoint
