Sample Disaster Recovery Scenario

Here are the steps for a sample scenario for
VMware Aria Operations for Networks
 Disaster Recovery (DR):
  1. Ensure that SRM is configured and up in both the protected and the recovery sites.
  2. Configure replication for each of the
    VMware Aria Operations for Networks
     nodes that are to be protected. While configuring the replication, provide adequate Recovery Point Objectives (RPO) time for the
    VMware Aria Operations for Networks
     instance. For example, if it is a
    VMware Aria Operations for Networks
     deployment with a single platform and collector nodes (medium size), then RPO of 45 minutes is good. But if it is a cluster with nodes having bricks of large size, then the adequate RPO should be provided. The snapshot interval configuration is specific to the user environment and requirement.
    The Site Recovery user interface with the forward replication option highlighted.
  3. Create protection group. Include the VMs that you want to protect under a specific protection group. The Site Recovery user interface displays options to create protection group for VMware Aria Operations for Networks.
  4. Create the recovery plan where you include the respective protection groups.The Site Recovery user interface displays options to create Recovery Plans by adding respective protection groups.
  5. Perform test recovery. This is to ensure that your recovery plan works as expected.
  6. SRM recommends that users perform planned migration at regular intervals to validate the integrity of the existingDR plan.
  7. Suppose the recovery site has a network configuration that forces the
    VMware Aria Operations for Networks
     VMs to come up with the new IPs. Recover the
    VMware Aria Operations for Networks
     VMs with a recovery plan that assumes no network change for the recovered VMs. Once the recovery of the VMs is reported as a success in
    VMware Aria Operations for Networks
    , assign new IP addresses manually to the
    VMware Aria Operations for Networks
     nodes, apply new certificates, and re-initialize the cluster.
  8. As IPv4 customization with SRM is not supported currently, as a work around you can perform DR with
    VMware Aria Operations for Networks
     assuming as if there is no network change.
    To manually assign the network settings:
    1. Run the
      change-network-settings
       to change the IP simultaneously on all platforms.
    2. For every platform whose IP is changed, run
      update-IP-change
       command on all the other nodes.
      For example, for the IP change of platform1 from IP1 to IP2, run the
      update-IP-change
       command on platform2 and platform3 with IP1 and IP2 as the arguments. For the IP change of platform2, run the
      update-IP-change
       command on platform1 and platform3.
    3. Run
      finalize-IP-change
       command once on platform1 after step1 and step 2 are completed.
    4. Run
      pair-collector set-platform --ip-or-fqdn <with-updated-ip-of-Platform1>
       on the collector node.
    5. Check the service status. If some of the services on the platform nodes are not running, reboot the nodes in the recommended order.
