Multi-Machine Blueprint fails to deploy on SDRS Reservation with NSX 6.0.1 (2097379)

  • 0 Ratings


  • When trying to create a multimachine blueprint in VMware vRealize Automation (formerly known as VMware vCloud Automation Center) with NSX 6.0.1 using a single datastore cluster, the Edge deployment fails.
  • In the Distributed Execution Manager (DEM) logs, located at C:\Program Files (x86)\VMware\vCAC\Distributed Execution Manager\DEM\Logs, you see entries similar to:

    System.Net.Http.HttpRequestException: Response status code indicates failure: Bad Request. Response
    <?xml version="1.0" encoding="UTF-8"?>
    <error><details>Failed to deploy edge appliance Edge-af656f4b-61dc-4990-9acc-d2327028c152-0.</details><errorCode>10020</errorCode>
    <rootCauseString>Operation failed in VC. Type of ManagedObjectReference was not correct.</rootCauseString><moduleName>vShield Edge</moduleName></error>


This issue occurs when NSX does not support deployment of Edges to a Datastore Cluster. This is a known limitation of NSX and not a limitation of VMware vRealize Automation (formerly known as VMware vCloud Automation Center).


This is a known issue affecting NSX for vSphere.

Currently, there is no resolution.

To work around this issue, provision the NSX Edge on a stand-alone datastore or on a SDRS cluster member datastore. Then provision the rest of the machines on the SDRS cluster where the SDRS engine will automatically choose the member datastore.
  1. Setup two reservation policies, SDRS Reservation Policy and Edge Reservation Policy
  2. Setup a reservation with the SDRS cluster level selected (SDRS Reservation)
  3. Assign the SDRS Reservation Policy to the reservation in Step #2
  4. Setup a reservation policy where either stand-alone or individual cluster member datastores (or both) are selected
  5. Assign the Edge Reservation Policy to the reservation in Step #4
  6. Setup multi-machine component blueprints to use SDRS Reservation Policy
  7. On the multi-machine blueprint itself, indicate Edge Reservation Policy for Edge deployment
