How to deploy a Hyper-V cluster with Powershell


You have two or more physical Hyper-V hosts on which you need to configure a Hyper-V cluster to be able to host virtual machines. This article provides step-by-step guidance on how to deploy a Hyper-V cluster with Powershell. This article is work in progress. The final outcome of this article will be a fully polished Powershell script to be used for efficiently deploying a Hyper-V cluster (coming soon).



First off, you should have configured the core/distribution switching infrastructure and the storage infrastructure for supporting your Hyper-V cluster. Designing the proper networking and storage environment for any Windows Failover Cluster (WFC) is outside the scope of this article. You can find out more about design considerations and best practices in my Windows Failover Clustering Design Handbook.

Each Hyper-V host which will join the WFC Hyper-V cluster will need to have sufficient RAM memory, sufficient storage IOPS in its local disks and sufficient number of physical Network Interface Cards (NICs). You will need to ensure redundancy for the shared storage cabling paths with LACP configured at the switch ports side.

Ensure that all your Hyper-V hosts have the latest Windows updates and the latest hardware vendor (for example pNICs and hard disks) drivers and firmware installed.

Remember that when setting up a single (standalone) Hyper-V server, most of the High Availability features of a WFC are not applicable, such as Live Migration, Quick Migration and Storage Multipathing.

Ensure that you have the latest Powershell version installed on all Hyper-V hosts. Powershell Desktop can be run on Windows only while Powershell Core can be run on any supported operating system, including MacOSX and Linux. Powershell Desktop latest version is 5.1 and no new versions will be coming out.

Powershell must have the Hyper-V module imported. The module should already be installed as part of the Hyper-V management tools.

Important note

The below Powershell cmdlets must be executed in an elevated Powershell terminal on each Hyper-V physical host. Please use these cmdlets at your own risk as they have been created by taking into account a certain environment/configuration. There may need to be changes in your own environment. First test in a lab environment before applying to production. Obviously all variables and environment-specific elements must be changed to reflect your own environment.

Install server roles and features

Run the following Powershell cmdlets to install the required server roles and features on each Hyper-V host.

Import-Module ServerManager
#Assuming multipath will be enabled in your shared storage, for example iSCSI
Add-WindowsFeature Multipath-IO
Install-WindowsFeature -Name Failover-Clustering -IncludeManagementTools
Install-WindowsFeature -Name Hyper-V -IncludeManagementTools
Install-WindowsFeature Hyper-V-Powershell

Powershell configuration cmdlets

Run the following cmdlets for configuring IP addressing of the Hyper-V hosts’ physical NICs.

#The below two commands must be run manually on each HyperV host for configuring an example storage vendor iSCSI storage. Refer to the storage vendor documentation for further instructions.
#mpiocpl.exe -> add support for ISCSI devices
#mpclaim –s –d
#Install storage vendor iSCSI driver on the Hyper-V host

# Adjust subnetting as per your requirements. The below configuration is only an example.
# The below example assumes four (4) NICs per physical host to be dedicated to shared storage traffic and other four (4) NICs per physical host to be dedicated to cluster traffic. 
#NIC1, NIC3, NIC5, NIC7 are used for shared storage traffic
#NIC2, NIC4, NIC6, NIC8 are used for WFC cluster traffic

#Configure MPIO using the Windows Server configuration tool
# Also refer to the following article for more details on the Windows Server MPIO feature configuration: 

#Create a NIC team for the NICs on each Hyper-V host to support the WFC cluster and client

Powershell script download

Based on the above cmdlets and analysis, a Powershell script will soon be made available which will take the Hyper-V hosts as input parameters and configure all Hyper-V failover cluster objects as per the input provided by the end user – Coming soon.
