Products

• VMware NSX
• VMware SDDC Manager / VCF Installer

Issue/Introduction

• When attempting a VMware Cloud Foundation (VCF) lifecycle upgrade, the upgrade process fails during the initial pre-check phase.
• The SDDC Manager user interface reports that the pre-check has failed because of the error message below :-
  
  Failed to load NSX Cluster from the Inventory, httpStatus :, error_code : 0

• On the SDDC manager, the error "Upgrade error occured: NSX Audit failed for <nsx_manager> Failed to load NSX Cluster from the Inventory, httpStatus : , error_code : 0" is recorded in /var/log/vmware/vcf/lcm/lcm.<date>.log-debug.

 

 

Environment

VMware NSX
VMware SDDC Manager

Cause

• The pre-check fails because the root/admin password on one of the cluster's NSX Managers is expired
• Because the password is expired, SDDC Manager is blocked from authenticating against that specific NSX manager node to collect inventory data, causing the entire pre-check sequence to halt.

Resolution

• Since the password has already expired and standard SSH/UI login attempts are blocked, the password must be reset via the GRUB boot menu.
• Follow the steps mentioned in the documentation to reset the password Resetting the Passwords of an Appliance
