Creating a Remote Replication CG
This section describes how to create a remote replication CG.
Prerequisites
- A storage pool has been created on the secondary remote replication device.
- The remote LUNs have not been mapped to a host.
Context
- On an A-B-C cascading 3DC network, create a remote replication CG on the storage system at site B.
The secondary LUN group of the HyperMetro consistency group between sites A and B is the primary LUN group of the remote replication consistency group between sites B and C.
- On an A-B, A-C parallel 3DC network, create a remote replication CG on the storage system at site A.
The local LUN group of the HyperMetro CG at site A is the primary LUN group of the remote replication CG.
Operation Description
- To create a remote replication CG, log in to DeviceManager and choose Services > Block Service > LUN Groups. Select the desired LUN group and choose Protect > Create Remote Replication.
- For details about how to create a remote replication CG, see the HyperReplication Feature Guide specific to your product model.
