About this task
You might want to resynchronize a source and a destination volume or qtree under the following circumstances:
- When you change the current source to a different volume or qtree.
- When you make a destination volume writable for application testing and then want to make it a SnapMirror destination again.
- When you need to recover from a disaster that disabled the source.
- When you want to reverse the functions of the source and the destination.
Note: When you perform resynchronization for the destination system, the contents on the destination are overwritten by the contents on the source.
