Installing vRealize Automation Agents
vRealize Automation uses agents to integrate with external systems. A system administrator can select
agents to install to communicate with other virtualization platforms.
vRealize Automation uses the following types of agents to manage external systems:
n
Hypervisor proxy agents (vSphere, Citrix Xen Servers and Microsoft Hyper-V servers)
n
External provisioning infrastructure (EPI) integration agents
n
Virtual Desktop Infrastructure (VDI) agents
n
Windows Management Instrumentation (WMI) agents
For high-availability, you can install multiple agents for a single endpoint. Install each redundant agent on a
separate server, but name and congure them identically. Redundant agents provide some fault tolerance,
but do not provide failover. For example, if you install two vSphere agents, one on server A and one on
server B, and server A becomes unavailable, the agent installed on server B continues to process work items.
However, the server B agent cannot nish processing a work item that the server A agent had already
started.
You have the option to install a vSphere agent as part of your minimal installation, but after the installation
you can also add other agents, including an additional vSphere agent. In a distributed deployment, you
install all your agents after you complete the base distributed installation. The agents you install depend on
the resources in your infrastructure.
For information about using vSphere agents, see “vSphere Agent Requirements,” on page 98.
Set the PowerShell Execution Policy to RemoteSigned
You must set the PowerShell Execution Policy from Restricted to RemoteSigned or Unrestricted to allow
local PowerShell scripts to be run.
For more information about the PowerShell Execution Policy, see Microsoft Technet article hh847748. If your
PowerShell Execution Policy is managed at the group policy level, contact your IT support for about their
restrictions on policy changes, and see Microsoft Technet article jj149004.
Prerequisites
n
Log in as a Windows administrator.
n
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.
n
For more information about PowerShell Execution Policy, run help about_signing or help Set-
ExecutionPolicy at the PowerShell command prompt.
Procedure
1 Select Start > All Programs > Windows PowerShell version > Windows PowerShell.
2 For Remote Signed, run Set-ExecutionPolicy RemoteSigned.
3 For Unrestricted, run Set-ExecutionPolicy Unrestricted.
4 Verify that the command did not produce any errors.
5 Type Exit at the PowerShell command prompt.
