ARIA Automation deploying on vSAN ESA returns 503 forbidden error: "Provisioning operation failed. The server sent HTTP status code 503: Service Unavailable"

Products

• VCF Operations/Automation (formerly VMware Aria Suite)
• VMware vCenter Server
• VMware vSphere ESXi

Issue/Introduction

• When deploying from Aria Automation to vSAN ESA, the Automation deployment fails and gives banner error:"Provisioning operation failed. The server sent HTTP status code 503: Service Unavailable"
• The same workload on other storage backend works without issue.

• You find error message's similar to:

Failed to validate credentials. Error: Failed to
connect to vCenter: Error: Read timed out

Provisioning operation faled. The server sent HTTP status code 503: Service Unavailable

 

Environment

VMware vCenter Server 8.0.2
VMware Aria Automation 8.x

Cause

Certain versions of the vSphere API expect a field `backingObjectId` during the reconfigure VM task, when deploying to vSAN ESA.

This is provided within vCenter, but not from Aria Automation.

Resolution

This is fixed in vSphere 8.0.3: please upgrade to 8.0.3 to resolve the issue.

If a patch for 8.0.2 is needed, please contact vSphere support to request a hotfix via the bug numbers contained in this article's Internal Notes.  

Workaround:

Provision to different storage, or provision directly on vCenter.
