if ($VMHost)
{

if ($ClusterName)
{

$ClusterArray.Add("$ClusterName") | Out-Null

if ($TestCluster -ne $True)
{

$ClusterArray.Add("$ClusterName") | Out-Null
}
Write-Host $ClusterName
}
}
} After that you can use your Cluster names to get CSV reports.

} You should change $ClusterNode to start monitoring.

As you may know, if you have SCCM 2007 agent on your Windows Server 2012, then you may see some problems with WMI. That issue blocks all WMI communication, Remote Desktop Services and Cluster functionality.
Recommended way to upgrade your SCCM 2007 to SCCM 2012, or you need to apply latest patches to your SCCM server.
You can disable all agents like this:

Set-Service -ComputerName $Server -Name "CcmExec" -StartupType "Disabled"
Set-Service -ComputerName $Server -Name "smstsmgr" -StartupType "Disabled"
Start-Sleep 1
} |

Set-Service -ComputerName $Server -Name "CcmExec" -StartupType "Disabled"
Set-Service -ComputerName $Server -Name "smstsmgr" -StartupType "Disabled"
Start-Sleep 1
} After that, service will stopped and startup type will be disabled to avoid automatic startup after reboot.

If you have “HP ProLiant Smart Array SAS/SATA Controller Driver for Windows Server 2012 x64 Edition (HPCISSS2.SYS) Version 62.26.0.64”, then you need to downgrade it to version 62.24.2.64. Otherwise you will see some problems and unexpected shutdowns on your Windows Servers and Hyper-V hosts.
But if you have many servers, it will not be easy to see which servers has latest version. So you use this script to get driver versions:

| $Servers = Get-Content C:\Servers.txt
foreach ($Server in $Servers)
{
Write-Host $Server
$ProductVersion = (Get-Item \\$Server\C$\Windows\System32\Drivers\HPCISSs2.sys).VersionInfo.ProductVersion
$Value = $Server + "," + $ProductVersion
Add-Content -Value $Value -Path C:\driverversions.txt
} |
$Servers = Get-Content C:\Servers.txt
foreach ($Server in $Servers)
{
Write-Host $Server
$ProductVersion = (Get-Item \\$Server\C$\Windows\System32\Drivers\HPCISSs2.sys).VersionInfo.ProductVersion
$Value = $Server + "," + $ProductVersion
Add-Content -Value $Value -Path C:\driverversions.txt
} You need to add your all servers into Servers.txt file.

} Btw, I haven’t tested this script yet. But that should work :)
