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.
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.
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.
Provision to different storage, or provision directly on vCenter.
