Add a 3rd node

Maybe i'll finish this at a later time ! ;)

Ok, prepping the new machine

Creating the disks, make it capable of running a VM in a VM

9..12 | foreach { New-VHD -Dynamic "d:\VHD\$_.vhdx" -SizeBytes 60GB }
9..12 | foreach {Add-VMHardDiskDrive -VMName Windows2016datacenter3 -ControllerType SCSI -Path "d:\vhd\$_.vhdx"}
get-VMProcessor -VMName Windows2016da* | Set-VMProcessor -ExposeVirtualizationExtensions $true

Add the new node to the domain and rename it to HC3

New-NetIPAddress -InterfaceAlias ethernet -IPAddress 192.168.1.1 -PrefixLength 24 -AddressFamily IPv4
Set-DnsClientServerAddress -InterfaceAlias ethernet -ServerAddresses 192.168.1.10
Add-Computer conlab.local -Credential conlab.local\Administrator -NewName HC3 -Restart

And add the necessary roles on my new node, HC3

Install-WindowsFeature -Name "Failover-Clustering","Hyper-V","RSAT-Clustering-PowerShell","Hyper-V-PowerShell" -includemanagementtools -Restart
