Prepare networking in Region B and perform a failover of vRealize Automation, vRealize Orchestrator, vRealize Business, vRealize Operations Manager, and vRealize Suite Lifecycle Manager to Region B if Region A becomes unavailable.
Reconfigure the NSX Instance for the Management Cluster in Region B If Region A becomes unavailable, prepare the network layer in Region B for a failover of the management applications. Change the role of the NSX Manager to primary, deploy the universal controller cluster, and synchronize the universal controller cluster configuration.
Recover the Control VM of the Universal Distributed Logical Router in Region B In the event of a site failure in Region A, dynamic routing in Region B might not be available. Deploy a Control VM for the universal distributed logical router sfo01m01udlr01 in Region B to recover dynamic routing in the environment. You then configure the recovered Control VM to provide dynamic routing for the SDDC management applications that are failed over.
Reconfigure the Universal Distributed Logical Router and NSX Edges for Dynamic Routing in Region B To support dynamic routing in Region B before you start disaster recovery from Region A, configure the universal distributed logical router sfo01m01udlr01 and NSX Edges lax01m01esg01 and lax01m01esg02. This configuration ensures that the management components of the SDDC continue to communicate using optimal routes in a fault-tolerant network.
Verify Establishment of BGP for the Universal Distributed Logical Router in Region B Verify that the UDLR for the management applications is successfully peering, and that BGP routing has been established in Region B. After you perform disaster recovery, they can continue communicating to keep the SDDC operational.
Enable Network Connectivity for the NSX Load Balancer in Region B Enable the network connectivity on lax01m01lb01 load balancer to support high-availability and distribute the network traffic load for vRealize Operations Manager, vRealize Suite Lifecycle Manager, and the Cloud Management Platform after disaster recovery to Region B.
Initiate Disaster Recovery of the Operations Management Applications in Region B In the event of a site failure in Region A, initiate disaster recovery of vRealize Suite Lifecycle Manager and of vRealize Operations Manager to keep the monitoring functionality of the SDDC running.
Initiate Disaster Recovery of the Cloud Management Platform in Region B In the event of a site failure in Region A, initiate disaster recovery of the vRealize Automation and vRealize Business components to keep the workload provisioning functionality of the SDDC available.
Post-Failover Configuration of the SDDC Management Applications After failover of the Cloud Management Platform, vRealize Operations Manager, and vRealize Suite Lifecycle Manager, you must perform additional tasks to ensure that the applications perform as expected.
