Environment

VMware NSX-T Datacenter

Cause

The VIP certificate is not correctly configured.
Identify the VIP certificate in the result of GET /api/v1/trust-management/certificates/

 {
    "pem_encoded" : "<Encoded certificate>",
    "has_private_key" : true,
    "used_by" : [ {
      "node_id" : "<Invalid node ID>",
      "service_types" : [ "MGMT_CLUSTER" ]
    } ],
    <snip>
    "_revision" : 2
  }

Valid node_id for MGMT_CLUSTER should be either site ID or a node ID of any existing Manager node.
The site ID can be found in the NSX Manager /config/site-manager/siteId file.

If the node_id is invalid, for example the ID of Manager node before restore, it delays inventory sync from VC to NSX Manager and CVDS is not recognized during precheck.

 

 

Resolution

1. Configure the VIP certificate of the Manager cluster again.
   POST /api/v1/trust-management/certificates/<cert-id>?action=apply_certificate&service_type=MGMT_CLUSTER
2. Clean up prechecks.
   POST /api/v1/nvds-urt?action=cleanup
3. Invoke precheck again.
