Setting up subnet mapping between production and recovery data centers

The subnet mapping operation eliminates the need to manually apply an IP address for each virtual machine at the recovery (DR) data center. After you have configured subnet mapping successfully, the IP addresses are computed programmatically, and applied to the virtual machines.

Note:

When you clone your virtual machines, ensure that you assign appropriate hostname and IP address to the cloned virtual machines.

Use the Recovery Automation option on the Resiliency Platform web console to map your production data center's subnet with the recovery (DR) data center's subnet. Note that the subnets will be discovered only when the virtual machines are running. If a virtual machine is down at the recovery data center, subnets will not be discovered.

To set up subnet mapping between production and recovery data centers

  1. Navigate

    Recovery Automation (navigation pane)
  2. Click Subnet in the Network Mapping page.
  3. Click Create Pair.
  4. In the Configure Subnet Mapping - Select Subnet page, select the subnet that should be the part of your subnet pair. You can organize the subnet into Host or Datacenter group using the Group By drop-down menu. Click Next.
  5. In the Configure Subnet Mapping - Pair Subnet, select the other member of your subnet pair, and click Submit. The created subnet pair is listed in the Network Mapping page.
