This section describes how to manage replication clusters.
Expanding a Replication Cluster
This operation enables you to expand the capacity of a replication cluster when the number of nodes in the cluster cannot meet service requirements.
Reducing a Replication Cluster
This operation enables you to reduce the capacity of a replication cluster by removing a replication node from it.
Adding a Remote Device
This operation enables you to establish a logical connection between a local device and a remote device for data transmission.
Removing a Remote Device
This operation enables you to remove an unnecessary remote device from a replication cluster.
Configuring a Cluster Service Credential
A replication cluster uses cluster authentication credentials for identification and authentication. To improve system security, you can periodically configure the cluster authentication credentials for a replication cluster. After configuring a cluster authentication credential, you need to change the remote cluster authentication credential of the corresponding remote device in the remote cluster simultaneously.
