Scenarios
You can attach a replication pair to a protected instance. Then, the production site disk is attached to the production site server, and the DR site disk is attached to the DR site server.
After protection is enabled for a protection group, when data is written into the production site disk, the same data is written into the DR site disk synchronously.

- If there are five replication pairs that are not attached to any protected instance, you cannot create any new replication pair.
Prerequisites
- The protection group is in the Available or Protecting state.
- The protected instance is in the Available or Protecting state.
- The replication pair is in the Available or Protecting state.
- The non-shared replication pair has not been attached to any protected instance.
Procedure
- Log in to the management console.
- Click Service List and choose Storage > Storage Disaster Recovery Service.
The Storage Disaster Recovery Service page is displayed.
- Locate the protection group where you want to attach replication pairs and click Protected Instances.
The protection group details page is displayed.
