Managing Remote Replication Pairs
This section describes how to set up a replication relationship between local and remote storage devices to copy data in the primary resource to the secondary resource on the remote device. If data on a storage device is lost due to a disaster, data on the other storage device is available, ensuring data security and availability.
- Viewing Remote Replication Pairs
This section describes how to view information about existing remote replication pairs and monitor their status. - Modifying a Remote Replication Pair
This section describes how to change the synchronization type, speed, and recovery policy of a remote replication pair. - Synchronizing a Remote Replication Pair
After the initial synchronization of a remote replication pair, if an application server writes data to the primary resource or you need to split the pair, data inconsistency between primary and secondary resources may occur. This section describes how to synchronize the remote replication pair to ensure data consistency between primary and secondary resources. - Splitting a Remote Replication Pair
This section describes how to split a remote replication pair if you want to enable secondary resources to save data in primary resources at a specific point in time, interrupt the remote replication link for maintenance, or expand the network bandwidth. After a remote replication pair is split, data written to the primary resource by the application server will not be synchronized to the secondary resource. This may cause data inconsistency between primary and secondary resources. - Performing a Primary/Secondary Switchover
This section describes how to switch the roles of primary and secondary resources of a remote replication pair. The data synchronization direction changes as the primary/secondary relationship changes. - Enabling Protection for Secondary Resource
Once protection for the secondary resource of a remote replication pair is enabled, the application server cannot modify data of the secondary resource, ensuring data security. - Disabling Protection for Secondary Resource
Once protection for the secondary resource of a remote replication pair is disabled, the application server can read and write to the secondary resource. This operation is mainly used when the secondary site takes over the service in DR scenarios. - Deleting a Remote Replication Pair
After you delete a remote replication pair, the replication relationship between primary and secondary resources of the remote replication pair will be deleted, and data in the primary resource will no longer be synchronized to the secondary resource. - Expanding the Capacity of LUNs in a Remote Replication Pair
