Configuring InfoScale DR Manager by using web console

Complete the following steps.

Click Operators > Installed Operators. Select InfoScale DR Manager.
In the main menu, click Global Cluster Membership. You can create a cluster membership.
Click Create GlobalClusterMembership in the upper-right corner of the screen as under.
Assign a Name and click Global Member Clusters. You can enter cluster details here.
Enter Cluster ID of the primary cluster first and its IP address in DR Controller Address. Optionally, you can enter its port number in DR Controller Port.
Note:
The IP address and port number are generated by using Load Balancer. An example of the command to generate the IP address is - oc -n infoscale-vtas expose deployment infoscale-dr-manager --name dr-lb-service --type LoadBalancer --protocol TCP --port 14155 --target-port 14155
Enter Cluster ID of the secondary cluster and its IP address in DR Controller Address. Optionally, you can enter its port number in DR Controller Port.
Note:
This is the IP address and port number of the peer cluster generated by using Load Balancer. Use the command mentioned in the above step.
Enter the Cluster ID of the primary cluster in Local Cluster Name.
Click Create. Wait till it is created. The newly created cluster is listed under Global Cluster Membership.
Repeat steps 1 to 8 on the secondary cluster. In step 7, ensure that you enter the cluster ID of the secondary cluster. After a successful configuration on the secondary cluster, the secondary cluster is the DR cluster.

Run the following command on the primary cluster to verify whether GCM is successfully configured - oc get gcm

An output similar to the following indicates a successful configuration.

NAME                        CLUSTER NAME   CLUSTER STATE   PROTOCOL

You can now configure Data Replication. Click Data Replication.
Click Create DataReplication in the upper-right corner of the screen. The following screen opens.
For the primary cluster, enter the Cluster Name, its IP address (Can be any Virtual IP address available in the same subnet) in Local Host Address, and its corresponding Net Mask in Local Net Mask.
For the secondary cluster, enter its name in Cluster Name, its IP address (Can be any Virtual IP address available in the same subnet) in Remote Host Address, and its corresponding Net Mask in Remote Netmask. Enter the network interface in Remote NIC.
Enter the Namespace for which you want to configure data replication.
In Local NIC, enter the network interface of the primary cluster.
Click Create. Wait till Data Replication is configured and gets listed.
