Issue/Introduction

  • When retrying a failed deployment in the VCF installer, the task Generate VCF Management Component Deployment Input Data fails. 
  • VCF Installer UI displays the error:
    An error occurred in task "Generate VCF Management Component Deployment Input Data". See Tasks panel to learn more.


  • In VCF Installer /var/log/vmware/vcf/domainmanager/domainmanager.log it shows a 401 Unauthorized error when attempting to retrieve build information from VCF Operations:

com.vmware.evo.sddc.orchestrator.exceptions.OrchTaskException: Preparing input for deploying VCF management components failed

Environment

  • VMware Cloud Foundation (VCF) 9.x
  • VCF Installer / SDDC Manager
  • VCF Operations 9.x

Cause

This issue occurs because the VCF Operations admin user password was changed manually or rotated, and it no longer matches the password stored in the active deployment workflow specification. This results in an authentication failure (HTTP 401) when the installer attempts to communicate with the VCF Operations API (CASA).

Resolution

To resolve this issue, manually update the VCF Operations password in the failed deployment workflow specification and retry the task.

 

Steps to follow:

  1. Log in to the SDDC Manager / VCF Installer via SSH.
  2. Obtain the current deployment workflow specification (JSON). - Refer KB 424770
  3. Update the VCF Operations admin password (and any other VCF Operations password fields) with the correct, current password.
  4. Patch the modified workflow back to the API. - Refer KB 424770
  5. Retry the failed task from the VCF Installer UI.
