This operation enables you to switch the roles of primary and secondary resources in a remote replication consistency group. If primary resources in the remote replication consistency group are faulty, you can perform a primary/secondary switchover. This operation enables secondary resources to become new primary resources, replacing the faulty primary resources to ensure service data continuity.
Prerequisites
- A primary/secondary switchover can be performed on an asynchronous remote replication consistency group when the following requirements are met:
Running Status is Split, Secondary Resource Data Status of all pairs in the consistency group is Consistent, and Secondary Resource Protection is Read and write.
- A primary/secondary switchover can be performed on a synchronous remote replication consistency group when the following requirements are met:
- Running Status is Normal, Secondary Resource Data Status of all member pairs is Synchronized, and Secondary Resource Protection of all member pairs is Read-only.
- Running Status is Split, Secondary Resource Data Status of all member pairs is Consistent, and Secondary Resource Protection of all member pairs is Read and write.
Procedure
- Choose Data Protection > Protection Entity > Protection Group > Remote Replication Consistency Group.
- Click More on the right of the desired remote replication consistency group and select Primary/Secondary Switchover.
- Confirm your operation as prompted.
