Resolving Orphaned HCX Tasks for SDDC environment within vCenter

Products

• VMware Cloud on AWS
• VMware HCX

Issue/Introduction

In some instances, HCX tasks may become orphaned and stuck in vCenter, with no ability for customers to cancel or complete these tasks through standard processes.

Environment

• SDDC Environment
• VMware vCenter
• VMware HCX

Cause

This issue typically occurs when a migration task becomes orphaned in vCenter but is no longer actively associated with any ongoing migration.

This can happen when

• A migration fails or succeeds but the task itself doesn't properly complete
• The state of the VM changes during the migration process
• The task loses its association with the actual migration

Common indicators include

• Task appears stuck at a high completion percentage
• No corresponding active migration visible in HCX interface
• Task cannot be cancelled through standard vCenter interfaces
• No actual data transfer or migration activity occurring

Resolution

If you encounter a hung HCX Cold Migration task in your SDDC environment

1. Open a support case with the HCX team at Broadcom
2. Provide details about the hung migration task
3. Broadcom Support will:
   • Verify no active migration is associated with the task
   • Confirm the task is truly orphaned in the system
   • Change the task status to "success" using backend management tools
