Aria Automation deployment fails and "No placement exists that satisfies all of the request requirements" error occurred

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

- When deploying VM, it fails with error

No placement exists that satisfies all of the request requirements. See 'Provisioning Diagram' for more information.
Original Task Error: 'Allocation filter error: Unable to find a common placement for compute 'vm' and its associated network resources on region '(Region_Name)[/provisioning/resources/provisioning-regions/ID]'. Reason: network filter: 
does not conform with the network configuration based on the networks of the blueprint and the selected network profile 'Network_Profile_Name - Network Profile''

- NSX-T is used for network profile.

- There is no configuration problem and it's not applied on this KB.

- The issue happened on specific vSphere Cluster which is newly added recently.

  The other cluster does not make a problem for deploying VM.

 

- If you check the number of Transport Nodes on the Transport Zone, there is more than 1000 Transport Nodes are configured.

Environment

Aria Automation 8.18.X with NSX-T used.

Cause

Aria automation calls Transport Node list without paging. And 1000 is the default page size in NSX.

So currently Aria automation can only handle 1000 nodes in a transport zone.

Resolution

Reducing Transport Nodes on Transport Zone under 1000 is the only workaround at this time.

Engineering is aware this problem and fix will be GAed.
