Huawei OceanStor 2200 V3 - Configuration Process

replication cannot implement data backup and disaster recovery in the scenario where a host
writes data to multiple dependent primary LUNs. A consistency group ensures data
consistency of secondary LUNs of all remote replication pairs in the group at the same point
in time (for example, the data of all secondary LUNs are the data copy of its primary LUN at
3:00 PM today), therefore ensures the data availability of primary LUNs after disaster
recovery.
3.8 Verifying the Configuration
After remote replication/consistency group is configured, you can view the status of the data
on the primary and secondary storage systems to check whether data replication between the
primary and secondary LUNs is successful.
3.1 Configuration Process
This section describes how to configure remote replication. You can set up a pair relationship
between the primary resource and secondary resource to implement data synchronization.
Figure 3-1 shows the process of configuring remote replication.
Figure 3-1 Process for configuring remote replication
Start
Check the remote
replication license
Add a remote device
Create a remote
replication
Mandatory Optional
Note:
Add a route
When the local and remote storage
systems connect through iSCSI host
ports, and they locate on different
network segments, add a route.
End
Prepare configuration
Obtain remote replication license and
identify port type for connecting primary
storage device and secondary storage
device.
