Install the SCVMM console before you install vRealize Automation DEM Workers that consume
SCVMM work items.
If you install the DEM Worker before the SCVMM console, you see log errors similar to the following
example.
Workflow 'ScvmmEndpointDataCollection' failed with the following exception: The term 'Get-
VMMServer' is not recognized as the name of a cmdlet, function, script file, or operable
program. Check the spelling of the name, or if a path was included, verify that the path is
correct and try again.
To correct the problem, verify that the SCVMM console is installed, and restart the DEM Worker
service.

The credentials used to manage the endpoint representing an SCVMM instance must have
administrator privileges on the SCVMM server.
The credentials must also have administrator privileges on the Hyper-V servers within the instance.
n
Hyper-V servers within an SCVMM instance to be managed must be Windows 2008 R2 SP1 Servers
with Hyper-V installed. The processor must be equipped with the necessary virtualization
extensions .NET Framework 4.5.2 or later must be installed and Windows Management
Instrumentation (WMI) must be enabled.

To provision a Generation-2 machine on an SCVMM 2012 R2 resource, you must add the following
properties in the blueprint.
Scvmm.Generation2 = true
Hyperv.Network.Type = synthetic
Generation-2 blueprints should have an existing data-collected virtualHardDisk (vHDX) in the
blueprint build information page. Having it blank causes Generation-2 provisioning to fail.
For more information, see “Congure the DEM to Connect to SCVMM at a Dierent Installation Path,” on
page 94.

vRealize Automation Port Requirements
vRealize Automation uses designated ports for communication and data access.
Although vRealize Automation uses only port 443 for communication, there might be other ports to open on
the system. Because open, unsecured ports might present security vulnerabilities, verify that only ports
required by your business applications are open.
