Error: UNABLE_TO_UPDATE_SOFTWARE_INFO during vSphere Lifecycle Manager Image Upload in VCF 9.1

Products

• VMware Cloud Foundation
• VMware SDDC Manager / VCF Installer

Issue/Introduction

• In VMware Cloud Foundation (VCF), operations fail when attempting to upload a vSphere Lifecycle Manager image, or when running the task to download ESX metadata, VIBs, and vendor add-ons within SDDC Manager.
  
  
  
  
• The /var/log/vmware/vcf/lcm/lcm-debug.log file on the SDDC Manager appliance records the following exception:
  

  ClassNotfoundException: com.vmware.cis.SessionStub
  at com.vmware.vcf.bindings.StubFactory.createStub(StubFactory.java:99)
  ...
  Caused by: java.lang.ClassNotFoundException: com.vmware.cis.SessionStub
  
  UNABLE_TO_UPDATE_SOFTWARE_INFO java.lang.RuntimeException: java.lang.ClassNotFoundException: com.vmware.cis.SessionStub

Environment

VMware Cloud Foundation (VCF) 9.x

Cause

A corrupted Java classpath or transient initialization failure within the SDDC Manager Lifecycle Management (vcf_lcm) service prevents the successful loading of the com.vmware.cis.SessionStub class, which is strictly required for vAPI/CIS communication between SDDC Manager and vCenter Server.

Resolution

Restart the Lifecycle Management service to reinitialize the Java runtime environment.

1. Access the SDDC Manager appliance via SSH using vcf credentials.
2. Switch to root: su -
3. Restart the LCM service: systemctl restart lcm
4. Validate service health: curl localhost/lcm/about (The service is ready when the command returns an HTTP 200 response).
5. Retry the failed image upload or synchronization task in the SDDC Manager UI.
