You can use this script to move only selected VMs live between Hyper-V Clusters.

		Write-Host Done.
	}

	}
}

You can add many VMs into array. Script will skip other VMs.

You can use this script to see how much quota user role has and how much consumes in cloud.

			# Add to Array

		}
	}
}

I tried to do best formating in this :) Output is even more readable now.

You can use this script to get details information of your Hyper-V Cluster:

1
2
(Get-Cluster | Get-ClusterNode | Select Name,@{label="CPU";expression={@(Get-WmiObject -ComputerName $_.Name -Class Win32_Processor)[0].Name}},@{label="Free Memory (GB)";expression={([math]::round(((Get-WmiObject -ComputerName $_.Name -Class Win32_OperatingSystem).FreePhysicalMemory / 1MB), 0))}},@{label="Free Memory (%)";expression={([math]::round(([math]::round(((Get-WmiObject -ComputerName $_.Name -Class Win32_OperatingSystem).FreePhysicalMemory / 1MB), 0))/([math]::round(((Get-WmiObject -ComputerName $_.Name -Class Win32_OperatingSystem).TotalVisibleMemorySize / 1MB), 0))*100))}},@{label="Total Memory (GB)";expression={([math]::round(((Get-WmiObject -ComputerName $_.Name -Class Win32_OperatingSystem).TotalVisibleMemorySize / 1MB), 0))}} | Sort Name) >> C:\info.txt
(Get-ClusterSharedVolume | Select -ExpandProperty SharedVolumeInfo | Select @{label="Name";expression={(($_.FriendlyVolumeName).Split("\"))[-1]}},@{label="Free Space (GB)";expression={([math]::round(((($_ | Select -Expand Partition).FreeSpace)/ 1GB), 0))}},@{label="Percent Free (%)";expression={([math]::round((($_ | Select -Expand Partition).PercentFree), 0))}},@{label="Total Space (GB)";expression={([math]::round(((($_ | Select -Expand Partition).Size)/ 1GB), 0))}} | Sort Name) >> C:\info.txt

That will output results into C:\info.txt.

You can find duplicated SPNs in your AD with this PowerShell script. That will output into txt file and console.

$ADObjects = Get-ADObject -Filter "objectClass -eq 'user' -and objectClass -eq 'computer'" -Properties "samaccountname","serviceprincipalname"
$Array = New-Object System.Collections.ArrayList
$Array.Clear();
 
foreach ($ADObject in $ADObjects)
{
   $SamAccountName = $ADObject.SamAccountName
   $ServicePrincipalName = $ADObject.ServicePrincipalName
 
   foreach ($SPN in $ServicePrincipalName)
   {
		$ReferenceObject = "$SamAccountName;$SPN"
 
		if ($Array -like "*$SPN")
		{
			$Matched = $Array -like "*$SPN"
			foreach ($Match in $Matched)
			{
				$MatchSAM = $Match.Split(";")[0]
				if ($MatchSAM -ne $SamAccountName)
				{
				   $Value = "$ReferenceObject%$Match"
				   Write-Host $Value
				   Add-Content -Value $Value -Path duplicated.txt
				}
			}
		}
		else
		{
			$Array.Add("$ReferenceObject")
		}
   }
}

You should split duplicated objects by %.

Life saver if you have many nodes in a Hyper-V cluster :)

$SANSwitches = Get-Cluster | Get-ClusterNode | % { Get-VMSAN -ComputerName $_.Name }
Foreach ($SANSwitch in $SANSwitches)
{
	$Name = $SANSwitch.Name
	$HBADetails = $SANSwitch | Select -Expand HBAs
	$PortAddress = $HBADetails.PortAddress
	$ComputerName = $HBADetails.PSComputerName
	Write-Host "Server: $ComputerName"
	Write-Host "Switch Name: $Name"
	Write-Host "Port Address: $PortAddress"
	Write-Host " "
}

Just buy me a cup of coffee if you like it :)

You can see Shared Nothing Migration logs under event logs:

Applications and Services Logs > Windows > Windows > Hyper-V-VMMS > Admin

Also you can get them via PowerShell:

Get-WinEvent Microsoft-Windows-Hyper-V-VMMS-Admin -MaxEvents 10 | Where Id -like "2041*"

I don’t see messages output on my server but you may give it a try :)
