If you need to sync OS name with VM name on Hyper-V, you can use KVP exchange feature:

$VM | Rename-VM -NewName $Hostname
} |

$KVPExport = $KVPData.GuestIntrinsicExchangeItems
$Hostname = ($KVPExport | where {$_.Name -eq "FullyQualifiedDomainName"}).Data
$VM | Rename-VM -NewName $Hostname
} Btw, I haven’t tested this script yet. But that should work :)

If you use HP 3PAR OS 3.1.1 MU2 (and only MU2) with Windows Server 2012, you need to run following command for both NTFS and REFS filesystem types. After that you will be able to do quick format on disk.
fsutil behavior set disabledeletenotify 1 |
fsutil behavior set disabledeletenotify 1 When you finish your quick format on disk, then you can re-enable with following command:
fsutil behavior set disabledeletenotify 0 |
fsutil behavior set disabledeletenotify 0 These steps are not required with later versions of HP 3PAR OS with Windows Server 2012.

You can search a VM name in your Hyper-V host list like this:
$VMName = "Server Name"
$Servers = Get-Content C:\servers.txt
foreach ($Server in $Servers)
{
$VMs = Get-WMIObject -Class Msvm_ComputerSystem -Namespace "root\virtualization" -ComputerName $Server
foreach ($VM in $VMs)
{
if ($VM.ElementName -eq $VMName)
{
Write-Host $Server
}
}
} |
$VMName = "Server Name"
$Servers = Get-Content C:\servers.txt
foreach ($Server in $Servers)
{
$VMs = Get-WMIObject -Class Msvm_ComputerSystem -Namespace "root\virtualization" -ComputerName $Server
foreach ($VM in $VMs)
{
if ($VM.ElementName -eq $VMName)
{
Write-Host $Server
}
}
} It uses WMI so both works on Windows Server 2008 and Windows Server 2012.

You may get this error when you try to open Failover Cluster Manager (Windows Server 2012):
Failover Cluster Manager failed while managing one or more cluster. The error was ‘An error occurred trying to display the cluster information.’. For more information see the Failover Cluster Manager Diagnostic channel.
You can fix this problem by this command via CMD:

| cd C:\Windows\System32\wbem
mofcomp .\ClusWMI.mof |
cd C:\Windows\System32\wbem
mofcomp .\ClusWMI.mof If you have SCCM agent on your server, then that might cause this error. Try to update your SCCM agent to latest version.

You can resolve ip addresses of many servers via Powershell.

| $Servers = Get-Content C:\Servers.txt
foreach ($Server in $Servers)
{
$IPAddress = $null
$IPAddress = [System.Net.Dns]::GetHostAddresses("$Server").IPAddressToString
Add-Content -Path C:\ServerName.txt -Value $Server
if ($IPAddress -eq $null)
{
$IPAddress = "Server IP cannot resolve."
}
Add-Content -Path C:\ServerIP.txt -Value $IPAddress
} |
$Servers = Get-Content C:\Servers.txt
foreach ($Server in $Servers)
{
$IPAddress = $null
$IPAddress = [System.Net.Dns]::GetHostAddresses("$Server").IPAddressToString
Add-Content -Path C:\ServerName.txt -Value $Server
if ($IPAddress -eq $null)
{
$IPAddress = "Server IP cannot resolve."
}
Add-Content -Path C:\ServerIP.txt -Value $IPAddress
} It creates two different txt file, so you can merge them in an excel file.

If ($IPAddress -like "172.29*")
{
Write-Host "Test Server"
Add-Content -Path C:\testservers.txt -Value $Server
}
else
{
Write-Host "Prod Server"
Add-Content -Path C:\prodservers.txt -Value $Server
}
} |
$Servers = Get-Content C:\Servers.txt
foreach ($Server in $Servers)

If ($IPAddress -like "172.29*")
{
Write-Host "Test Server"
Add-Content -Path C:\testservers.txt -Value $Server
}
else
{
Write-Host "Prod Server"
Add-Content -Path C:\prodservers.txt -Value $Server
}
} As you see, i split them into 2 different groups.

if ($TestFC)

Add-Content -Value $Value -Path C:\Servers.txt

}
} |
$Servers = Get-Content C:\hosts.txt
foreach ($Server in $Servers)

Write-Host $Server
foreach ($VM in $VMs)

$TestFC = $VM | Select -expand FibreChannelHostBusAdapters
if ($TestFC)
{
$Value = $VM.Name + "," + $VM.ComputerName
Add-Content -Value $Value -Path C:\Servers.txt
}
}
} I’ve added all my Hyper-V hostnames into C:\hosts.txt to use this script.
