Resolution

Add host to cluster in SDDC Manager with cluster expansion workflow from the API.

Follow the below steps

1. Take a snapshot of the SDDC Manager VM through vCenter UI.
2. SSH to SDDC Manager with vcf and su to root.
3. Create the Cluster expansion spec file with the name clusterExpansionSpec.json - Refer ClusterExpansionSpec 
4. Generate the token using Token API.

   curl -X POST -H "Content-Type: application/json" -d '{"username": "<SSO_USERNAME>","password": "<SSO_PASSWORD>"}' https://<sddcmanagerIp>/v1/tokens | json_pp

   Sample

   curl -X POST -H "Content-Type: application/json" -d '{"username": "[email protected]","password": "****"}' https://198.51.100.1/v1/tokens | json_pp

5. Login to SDDC Manager and execute the cluster expansion *Validation* API.

   curl 'https://<SDDC_MANAGER_FQDN>/v1/clusters/<CLUSTER_ID>/validations' -i -X POST -H 'Content-Type: application/json' -H 'Authorization: Bearer <BEARER_TOKEN from above command>' -d @clusterExpansionSpec.json

6. Once the Add Host validation API succeeds, the actual cluster expansion (or add host) API can be triggered.
