24 Verify that the installation is successful.
25 (Optional) Add multiple agents with dierent congurations and an endpoint on the same system.
What to do next
For high-availability, you can install and congure a redundant agent for your endpoint. Install each
redundant agent on a separate server, but name and congure the agents identically.
Installing the EPI Agent for Citrix
External provisioning Integration (EPI) PowerShell agents integrate Citrix external machines into the
provisioning process. The EPI agent provides on-demand streaming of the Citrix disk images from which
the machines boot and run.
The dedicated EPI agent interacts with a single external provisioning server. You must install one EPI agent
for each Citrix provisioning server instance.
Citrix Provisioning Server Requirements
A system administrator uses External Provisioning Infrastructure (EPI) agents to integrate Citrix
provisioning servers and to enable the use of Visual Basic scripts in the provisioning process.
Installation Location and Credentials
Install the agent on the PVS host for Citrix Provisioning Services instances. Verify that the installation host
meets “Citrix Agent Host Requirements,” on page 111 before you install the agent.
Although an EPI agent can generally interact with multiple servers, Citrix Provisioning Server requires a
dedicated EPI agent. You must install one EPI agent for each Citrix Provisioning Server instance, providing
the name of the server hosting it. The credentials under which the agent runs must have administrative
access to the Citrix Provisioning Server instance.
Consult the vRealize Automation Support Matrix for information about supported versions of Citrix PVS.
Citrix Agent Host Requirements
PowerShell and Citrix Provisioning Services SDK must be installed on the installation host prior to agent
installation. Consult the vRealize Automation Support Matrix on the VMware Web site for details.
Verify that Microsoft PowerShell is installed on the installation host before agent installation. The version
required depends on the operating system of the installation host. See Microsoft Help and Support.
You must also ensure that the PowerShell Snap-In is installed. For more information, see the Citrix
Provisioning Services PowerShell Programmer's Guide on the Citrix Web site.
MS PowerShell Execution Policy is set to RemoteSigned or Unrestricted. See “Set the PowerShell Execution
Policy to RemoteSigned,” on page 98.
For more information about PowerShell Execution Policy, run help about_signing or help Set-
ExecutionPolicy at the PowerShell command prompt.
