Consistency Split of SmartMove splits multiple related pairs at the same time to ensure data consistency at different points in time before and after the splitting. It is applicable to scenarios where data is stored in multiple different associated volumes. In this scenario, using Split cannot ensure that information in each volume at each point in time is associated. If data in certain volumes is missing, data in other volumes will become invalid.
Prerequisites
- SmartMove pairs have been created.
- Running Status of the SmartMove pairs is Normal.
Precautions
- After a SmartMove pair is split, write requests sent by production hosts to the source common volume will no longer be synchronized to the target volume.
Procedure
- Choose Resources > Tuning > SmartMove.
- Select desired SmartMove pairs and click Consistency Split.
The Perform Consistency Splitting page is displayed.
- Select desired pairs from the Available Pairs area. They will be automatically added to the Selected Pairs area.
- Click OK.
