适用于

  •    集群模式 Data ONTAP 8.2    
  •    集群模式 Data ONTAP 8.3     
  •    ONTAP 9    
  •    ONTAP 9.1    
  •    ONTAP 9.2 

说明

SMTape 用于复制无法通过 WAN 发送的数据。SMTape 允许您通过磁带创建初始 SnapMirror 传输,然后利用 WAN 进行未来更新来建立 SnapMirror 关系。

重要注意事项:从集群 ONTAP 8.3 开始,仅支持磁带使用 SMTape 进行磁带传播。  当 -file-path option is used to direct the data stream to disk image, the baseline copy will be written at a maximum of 5 MB/s, slower than most WAN connections.  For this reason, use of the -file-path option as an alternative to transferring SnapMirror data over the WAN is not recommended and is not supported.

Note that the below process can be used only in Testing Scenarios.
