Table 1‑6. Running Visual Basic Scripts During Provisioning Checklist
Task Location Details
Install and configure the EPI agent for
Visual Basic scripts.
Typically the Manager Service host See Installing vRealize Automation 7.3.
Create your visual basic scripts.
Machine where EPI agent is installed vRealize Automation includes a sample
Visual Basic script
PrePostProvisioningExample.vbs in
the Scripts subdirectory of the EPI agent
installation directory. This script contains a
header to load all arguments into a
dictionary, a body in which you can
include your functions, and a footer to
return updated custom properties to
vRealize Automation.
When executing a Visual Basic script, the
EPI agent passes all machine custom
properties as arguments to the script. To
return updated property values to
vRealize Automation, place these
properties in a dictionary and call a
function provided by vRealize Automation.
Gather the information required to
include your scripts in blueprints.
Capture information and transfer to your
infrastructure architects
Note A fabric administrator can create
a property group by using the property
sets ExternalPreProvisioningVbScript
and ExternalPostProvisioningVbScript to
provide this required information. Doing
so makes it easier for blueprint architects
to include this information correctly in
their blueprints.
n
The complete path to the Visual Basic
script, including the filename and
extension. For example, %System
Drive%Program Files
(x86)\VMware\vCAC
Agents\EPI_Agents\Scripts\Send
Email.vbs.
n
To run a script before provisioning,
instruct infrastructure architects to
enter the complete path to the script
as the value of the custom property
ExternalPreProvisioningVbScrip
t. To run a script after provisioning,
they need to use the custom property
ExternalPostProvisioningVbScri
pt.
Using vRealize Automation Guest Agent in Provisioning
You can install the guest agent on reference machines to further customize a machine after deployment.
You can use the reserved guest agent custom properties to perform basic customizations such as adding
and formatting disks, or you can create your own custom scripts for the guest agent to run within the
guest operating system of a provisioned machine.
After the deployment is completed and the customization specification is run (if you provided one), the
guest agent creates an XML file that contains all of the deployed machine's custom properties
c:\VRMGuestAgent\site\workitem.xml, completes any tasks assigned to it with the guest agent
custom properties, and then deletes itself from the provisioned machine.
