4.8.3 Edge Cluster Failure
In the unlikely event that the edge cluster fails in one data center, North-South traffic no longer flows and potentially the NSX Controller nodes are offline, which will interrupt the ability to create new networking components within the VMware NSX solution.
The recovery from this scenario is as follows:
1. Instigate DR process to failover workloads from failed site.
2. Promote secondary NSX Manager as primary.
3. Redeploy NSX Controller nodes in recovery site.
4. Redeploy NSX Edge services gateways in the recovery site.
5. Normal operations resume.
An alternative approach is to change the locale ID to the target site, which will send virtual machine traffic across the WAN and egress the target data center until the edge cluster is recovered.
Note If you do not have local egress enabled, you must change the locale ID so that the traffic egresses the correct data center during a failure scenario.
