VM Instance UUID mismatch in Aria Automation after HCX RAV migration.

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

1. Day 2 actions for affected deployments are grayed out and unavailable (except for "Delete" and "Unregister").
2. VM deployments shows status as "Missing" or "Unknown."
3. Backup jobs (e.g., Dell Networker, Veeam) for migrated VMs fail or trigger a new full backup.
4. The issue is observed after performing HCX Replication Assisted vMotion (RAV) migrations of virtual machines between clusters within the same vCenter Server environment.

 

 

Environment

• VMware Aria Automation 8.18.x
• VMware HCX 4.11.x

Cause

1. Mismatch in the VM Instance UUID (vc.uuid) introduced during an HCX RAV migration within a single vCenter. vCenter Server requires every VM in its database to have a unique vc.uuid.
2. During the migration cutover, both the source and target VM temporarily coexist.
3. To prevent a collision, vCenter automatically assigns a new instanceUuid to the target VM. Aria Automation loses its association because it relies on the original UUID.

Resolution
