Upgrading to VMware NSX for vSphere 6.2.5 resolves the issue.
Symptoms:
In a VMware NSX for vSphere 6.2.4 environment where an NSX Edge is upgraded or re-deployed, these symptoms are seen:
- Anti-affinity rules are missing.
- In the vSphere Web Client > NSX Cluster > Manage > DRS Rules, there are no entries under this configuration.
