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.
Remote Replication Pair
l The primary and secondary storage systems of the remote replication task are correctly
connected to the application server.
l Initial synchronization of the remote replication task has been complete.
Step 1 Map the primary and secondary LUNs to the host.
1. Log in to DeviceManager. Choose Provisioning > LUN > LUN Group. Click
Create to create LUN groups and add the primary and secondary LUNs of the remote
replication task to corresponding LUN groups.
2.
Choose Provisioning > Mapping View. Choose the mapping view that the host
group which holds the application servers belongs to. Then add the newly created LUN
group to this mapping view.
NOTE
To check on a standby server whether data replication succeeds, you need to mount the secondary LUN to the
standby server. Before mounting the secondary LUN, split the LUN and set Status of Secondary Resource
Protection to Read/Write.
Step 2 Check whether data replication succeeded.
1. Log in to the application server at the primary site and write file X.txt to the primary
LUN. When Pair Running Status is Normal, go to the next step.
2. Log in to DeviceManager at the primary site. Choose Data Protection > Remote
Replication > Remote Replication Pair. Click the remote replication to be
synchronized. Choose More > Synchronize to perform the synchronization manually.
3. Log in to the standby server at the secondary site to check whether data file X.txt exists
on the secondary LUN.
– If yes, data replication succeeded.
– If no, log in to DeviceManager at the primary site. Choose
Data Protection >
Remote Replication > Remote Replication Pair. Click the remote replication task
to be synchronized. Choose More > Synchronize to perform the synchronization
manually.
Step 3 Check whether a primary/secondary switchover can be performed on the secondary site.
1. Log in to DeviceManager at the secondary site. Choose Data Protection > Remote
Replication > Remote Replication Pair and perform the following operations.
a. Select the remote replication pair to be split and choose More > Split.
b. Click Properties. Modify Status of secondary resource protection to Read/Write
to set the secondary LUN to readable and writable.
