l The local and remote storage devices must support remote replication.
l The remote storage device is added already, and secondary resource is created on the
remote device.
l The storage capacities of primary and secondary LUNs are the same.
l The statuses of primary and secondary LUNs are healthy.
l The primary and secondary LUNs have not configured any feature that conflicts with the
remote replication feature.
Procedure
Step 1 Log in to DeviceManager.
Step 2 Choose
Data Protection > Remote Replication > Remote Replication Pair.
Step 3 Click Create.
The Create Remote Replication Pair dialog box is displayed.
Step 4 Specify the replication mode and resource type for remote replication.
1. Set Replication Mode to Synchronous.
2. Select a primary resource type from the drop-down list.
Possible values of the primary resource type are LUN, Microsoft Exchange, VMware,
Hyper-V, Oracle and SQL Server.
3. Optional: When Microsoft Exchange, VMware, Hyper-V, Oracle or SQL Server is
selected as the primary resource type, click Select, select an application instance, and
click OK.
NOTE
When you create a remote replication task using the storage resources created based on an application,
all available LUNs of the application are displayed in Primary Resource. For details about how to
create storage resources based on applications, see Creating Storage Resources Based on
Applications in the OceanStor V3 Series V300R006 Basic Storage Service Guide for Block. For
OceanStor 2000 V3 series (excluding 2600 V3 Video Surveillance Edition and 2800 V3), 5000 V3
series, and 6000 V3 series, you can configure the storage resources created based on applications. For
OceanStor 18000 V3 series, the storage resources created based on applications are not displayed when
you create a remote replication pair, because this type of storage resources is not supported by
OceanStor 18000 V3 series.
4. Click Next.
Step 5 Select synchronous remote replication primary and secondary resources.
1. From the Remote device drop-down list, select the remote device where the secondary
resource resides.
NOTE
If no remote device exists, click Add to add one.
2. In the Primary Resource area, select the remote replication primary resource.
3. In the Secondary Resource area, select the remote replication secondary resource.
4. Click Add to Pairs.
The selected primary and secondary resources are added to Pairs.
5. Click Next.
