NSX Local Manager "import to GM" option is greyed out

Products

• VMware NSX

Issue/Introduction

• Created a new Global Manager and added 2 Local Manager nodes. One node is able to "import" the config but the other cannot. 
• Unable to click "import to GM" in Local Manager UI:
   

Environment

VMware NSX

Cause

• Running the following API shows "onboarding status" 
  

  GET https://<gm-ip>/global-manager/api/v1/global-infra/sites/<site>/onboarding/status
  
  {
  
      "site_id": "###-###",
  
      "status": "BLOCKED_USER_REJECT",
  
      "details": {
  
          "error_messages": [
  
              {
  
                  "error_code": 606136,
  
                  "error_message": "Config onboarding blocked according to user preference at site <site-name>."
  
              }
  
          ],
  
          "site_backup_reference": ""
  
      },
  
      "timestamp": ############
  
  }

• Below API shows "ignore_import" flag set to true. This is preventing the import workflow.  
  

  GET https://<lm_ip>/global-manager/api/v1/global-infra/sites/<site_name>/onboarding/preferences
  
  {
  
      "site_id": "<site-name>",
  
      "ignore_import": true,      <----------- 
  
      "resource_type": "SiteOnboardingPreference",
  
      "id": "/global-infra/sites/<sites>/onboarding-preferences/default",
  
      "display_name": "/global-infra/sites/<sites>/onboarding-preferences/default",
  
      "_system_owned": true,
  
      "_protection": "NOT_PROTECTED",
  
      "_create_time": #############,
  
      "_create_user": "<user_account>",
  
      "_last_modified_time": #############,
  
      "_last_modified_user": "<user_account>",
  
      "_revision": 1
  
  }

Resolution

• Update "ignore_import" flag to "false" with the following API:
  

  PUT https://<lm_ip>/global-manager/api/v1/global-infra/sites/<site>/onboarding/preferences
  {
    "site_id": "<site_id>",
    "ignore_import": false
  }

  NOTE: You can copy the output from the "GET" command, change the "ignore_import" flag and paste this content into the API body.
