For high-availability, you can install multiple agents for a single endpoint. Install each redundant agent on
a separate server, but name and configure 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 finish 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.
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 the Microsoft PowerShell article about
Execution Policies. 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 the Microsoft PowerShell article about
Group Policy Settings.
Prerequisites
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.

For more information about PowerShell Execution Policy, run help about_signing or help Set-
ExecutionPolicy at the PowerShell command prompt.
Procedure
1 Using an administrator account, log in to the IaaS host machine where the agent is installed.
2 Select Start > All Programs > Windows PowerShell version > Windows PowerShell.
3 For Remote Signed, run Set-ExecutionPolicy RemoteSigned.
4 For Unrestricted, run Set-ExecutionPolicy Unrestricted.
5 Verify that the command did not produce any errors.
6 Type Exit at the PowerShell command prompt.
Choosing the Agent Installation Scenario
The agents that you need to install depend on the external systems with which you plan to integrate.
