You can use the snapmirror break command to convert a SnapMirror destination, with read-only status, to a writable volume or qtree.
You might want to convert a destination to a writable volume or qtree to perform one of the following tasks:
- Data migration—Moving data from one volume or qtree (original source) to another volume or qtree (present destination) and make the data on the destination accessible and writable.
- Disaster recovery—If your source becomes unavailable, and you want your present destination to substitute as the users’ retrieval and input source.
- Application testing—You want to make your current destination volume or qtree writable to test a new application on a mirrored replication of your current data rather than risk corruption of original data on the source volume or qtree.
Converting the destination to a writable volume or qtree enables you to use data on the destination, especially when the original source is unavailable.
