Setting up replication
The following procedure lists high-level tasks to set up replication for this scenario.
To set up replication across zones within the same Google cloud region
  1. Create a VPC network with a valid CIDR block, for example, 10.0.0.0/16.
  2. Create two subnets - one subnet for the primary site in Zone1 and the second subnet for the secondary site in Zone2 with valid CIDR range, for example, 10.0.1.0/24 and 10.0.2.0/24 respectively.
  3. Launch the VM instances in the primary and secondary subnets, and install InfoScale on the instances.
  4. Verify connectivity between the virtual private IP addresses of the instances.

    1. Create VxVM disk groups, VxVM volumes, Replicated Volume Group (RVG), and RLinks.
    2. Set up replication between the instances using private IP address or virtual private IP address.
    3. Verify the status of replication.
    # vradmin -g dg_name repstatus rvg_name
    Ensure that the status shows:
    Replication status: replicating (connected)
