Suspending A Remote Replication Group

Use the asyncRemoteReplicationGroup command to stop data transfer between a primary virtual disk and a secondary virtual disk in a replication relationship without disabling the replication relationship. Suspending a replication relationship group lets you control when the data on the primary virtual disk and data on the secondary virtual disk are synchronized. Suspending a replication relationship group helps to reduce any performance impact to the host application that might occur while any changed data on the primary virtual disk is copied to the secondary virtual disk.

When a replication relationship is in a suspended state, the primary virtual disk does not make any attempt to contact the secondary virtual disk. Any writes to the primary virtual disk are persistently logged in the replication repository virtual disks. After the replication relationship resumes, any data that is written to the primary virtual disk is automatically written to the secondary virtual disk. Only the modified data blocks on the primary virtual disk are written to the secondary virtual disk. Full synchronization is not required.

This example shows the suspend remoteReplicationGroup command: 
suspend asyncRemoteReplicationGroup ["
                                    asyncRemoteReplicationGroupName"];

The replication relationship group remains suspended until you use the resume asyncRemoteReplicationGroup command to restart synchronization activities.

This example shows the resume remoteReplicationGroup command: 
resume asyncRemoteReplicationGroup ["
                                    asyncRemoteReplicationGroupName"];
