Generating reports of VMs with Dynamic Disk

Posted in Virtual Machine Manager, Windows Powershell, Windows Server | No Comment | 3,579 views | 22/08/2013 10:12

This is pretty cool and detailed report for VMs with Dynamic Disk. It requires SCVMM 2012 to get details but it’s possible to change it to use Hyper-V PowerShell Cmdlet.

$VMs = Get-VM
foreach ($VM in $VMs)
{
	$Disks = Get-VM $VM | Get-SCVirtualHardDisk
	foreach ($Disk in $Disks)
	{
		if ($Disk.VHDType -ne "FixedSize")
		{
			$DiskLocation = $Disk.Location
			$CSVVolume = ($Disk.Location.Split("\"))[2]
			$DiskName = ($Disk.Location.Split("\"))[-1]
			$DiskSize = ([math]::round(($Disk.Size/1GB), 0))
			$DiskMSize = ([math]::round(($Disk.MaximumSize/1GB), 0))
			$DiskHost = $Disk.VMHost
			$CSVFreeSpace = ([math]::round(((Get-SCStorageVolume | where VMHost -eq $DiskHost | Where Name -like "*$CSVVolume*").FreeSpace/1GB), 0))
			$CSVCapacity = ([math]::round(((Get-SCStorageVolume | where VMHost -eq $DiskHost | Where Name -like "*$CSVVolume*").Capacity/1GB), 0))
			$Value = $VM.Name + ";" + $DiskName + ";" + $CSVVolume + ";" + $CSVFreeSpace + ";" + $CSVCapacity + ";" + $DiskMSize + ";" + $DiskSize + ";" + $DiskHost
			Add-Content -Path DiskUsage.txt -Value $Value
		}
	}
}

It also shows CSV volume name, capacity and free space information.

Windows Server 2012 Version Check

Posted in Windows Powershell, Windows Server | No Comment | 1,943 views | 18/08/2013 00:25

You can check Windows Server 2012 version with following script:

$Servers = Get-Content "C:\Servers.txt"
foreach ($Server in $Servers)
{
	Write-Host "--------------------"
	Write-Host $Server
	$Version = (Get-WmiObject -Class Win32_OperatingSystem -ComputerName $Server).Version
	Write-Host $Version
	if ($Version -like "6.2*")
	{
		Add-Content -Value $Server -Path C:\Windows2012Servers.txt
	}
}

That will output all results into Windows2012Servers.txt file.

Windows Server Uptime Check Script after Patch Restarts

Posted in Windows Powershell, Windows Server | No Comment | 12,367 views | 17/08/2013 22:41

This is pretty cool script after patch updates to check which servers are successfully rebooted.

$Servers = Get-Content C:\UpdateServers.txt
function WMIDateStringToDate($Bootup) {
        [System.Management.ManagementDateTimeconverter]::ToDateTime($Bootup)
}
foreach ($Server in $Servers)
{
	$OS = Get-WmiObject Win32_OperatingSystem -ComputerName $Server
	$Bootup = $OS.LastBootUpTime
	$LastBootUpTime = WMIDateStringToDate($Bootup)
	$Now = Get-Date
	$Uptime = $Now - $LastBootUpTime
	$d = $Uptime.Days
	$h = $Uptime.Hours
	$m = $uptime.Minutes
	$ms= $uptime.Milliseconds
	$a = "$Server Up for: {0} days, {1} hours, {2}.{3} minutes" -f $d,$h,$m,$ms
	Write-Host "$a" -ForegroundColor Green
}

I hope that helps :)

Getting unused directories in Hyper-V ClusterStorage Volumes via PowerShell

Posted in Virtual Machine Manager, Windows Powershell | No Comment | 2,667 views | 15/08/2013 10:25

You may export and move a VM to another host or volume, or maybe you may delete a VM but configuration and VHD files may still exist on old location. In that case, you can use this script to find that old VM directories.

# Get Cluster Nodes
$ClusterNodes = "Cluster01Node01","Cluster02Node02"
 
foreach ($ClusterNode in $ClusterNodes)
{
	$Volumes = Get-ChildItem -Directory -Path \\$ClusterNode\C$\ClusterStorage\
 
	foreach ($Volume in $Volumes)
	{
		$ConfigFolders = Get-ChildItem -Directory -Path \\$ClusterNode\C$\ClusterStorage\$Volume
 
		foreach ($ConfigFolder in $ConfigFolders)
		{
			$Result = "0";
			$VMName = "";
 
			$ClusterNodes = Get-Cluster $ClusterNode | Get-ClusterNode
 
			foreach ($ClusterNode in $ClusterNodes)
			{				
				$VMs = Get-VM -ComputerName $ClusterNode
 
				foreach ($VM in $VMs)
				{
					$FullName = $ConfigFolder.FullName
					$FullPath = "C:\" + $FullName.Split("\")[4] + "\" + $FullName.Split("\")[5] + "\" + $FullName.Split("\")[6]
					if ($FullPath -like $VM.ConfigurationLocation)
					{
						$Result = 1;
					}
 
					$VirtualDisks = Get-VM -ComputerName $ClusterNode -Name $VM.Name | Get-VMHardDiskDrive
 
					foreach ($VirtualDisk in $VirtualDisks)
					{						
						if ($VirtualDisk.Path -like "$FullPath*")
						{
							$Result = 1;
						}
					}
				}
			}
 
			if ($Result -ne "1")
			{
				Write-Warning $ConfigFolder.FullName
			}
		}
	}
}

$ClusterNodes should contain different Cluster’s only one nodes. Using with that node name, we can query other nodes too.

How to create SQL Server 2012 template on Hyper-V

Posted in Windows Server | No Comment | 3,609 views | 14/08/2013 09:22

You can create Microsoft SQL Server 2012 template on Hyper-V if you want to do unattended setups.

Follow the steps:

1) Install Windows Server 2012, do latest updates and your customizations.

2) Make a new folder called “Scripts” under “C:\Windows\Setup”. Path should be:

C:\Windows\Setup\Scripts

3) Make a new file called “SetupComplete.cmd” under “C:\Windows\Setup\Scripts”. Path should be:

C:\Windows\Setup\Scripts\SetupComplete.cmd

4) Mount SQL Server 2012 DVD and copy that into a directory like “C:\PATH\OF\MSSQL\”

5) Write SQL unattended setup commands into “SetupComplete.cmd”.

C:\PATH\OF\MSSQL\setup.exe /ConfigurationFile="C:\PATH\OF\MSSQL\ConfigurationFile.ini" /q

6) You can use this ConfigurationFile.ini as a template and customize it.

;SQL Server 2012 Configuration File
[OPTIONS]
ACTION="Install"
ENU="True"
UIMODE="Normal"
QUIET="False"
QUIETSIMPLE="False"
UpdateEnabled="False"
FEATURES=SQLENGINE,REPLICATION,FULLTEXT,CONN,IS,BC,SSMS,ADV_SSMS
UpdateSource="MU"
HELP="False"
INDICATEPROGRESS="False"
X86="False"
INSTALLSHAREDDIR="C:\Program Files\Microsoft SQL Server"
INSTALLSHAREDWOWDIR="C:\Program Files (x86)\Microsoft SQL Server"
INSTANCENAME="MSSQLSERVER"

ERRORREPORTING="False"
INSTANCEDIR="C:\Program Files\Microsoft SQL Server"
AGTSVCACCOUNT="NT Service\SQLSERVERAGENT"
AGTSVCSTARTUPTYPE="Manual"
ISSVCSTARTUPTYPE="Automatic"
ISSVCACCOUNT="NT Service\MsDtsServer110"
COMMFABRICPORT="0"
COMMFABRICNETWORKLEVEL="0"
COMMFABRICENCRYPTION="0"
MATRIXCMBRICKCOMMPORT="0"
SQLSVCSTARTUPTYPE="Automatic"
FILESTREAMLEVEL="0"
ENABLERANU="False"
SQLCOLLATION="Turkish_CI_AS"
SQLSVCACCOUNT="NT Service\MSSQLSERVER"
SQLSYSADMINACCOUNTS=".\Administrator"
SECURITYMODE="SQL"
ADDCURRENTUSERASSQLADMIN="False"
TCPENABLED="1"
NPENABLED="0"
BROWSERSVCSTARTUPTYPE="Disabled"
FTSVCACCOUNT="NT Service\MSSQLFDLauncher"

7) Sysprep your Windows Server.

After these steps, you can deploy your VHD into different VMs.

Set User Role Quota for each Cloud Profile in SCVMM 2012 SP1 – Method 2

Posted in Virtual Machine Manager, Windows Powershell | No Comment | 1,915 views | 12/08/2013 14:17

You can set User Role Quota for each Cloud Profile in SCVMM 2012 SP1.

$UserRoles = "BackOffice","CallCenter"
foreach ($UserRole in $UserRoles)
{
	$UserRole = Get-SCUserRole $UserRole
	$Clouds = "DMZ Cloud","Prod Cloud","Test Cloud"
	foreach ($Cloud in $Clouds)
	{
	   $MyCloud = Get-SCCloud $Cloud
	   $CloudUsage = Get-SCCloudUsage -Cloud $MyCloud -UserRole $UserRole
	   $CPUCount = $CloudUsage.CPUUsageCount
	   $Memory = $CloudUsage.MemoryUsageMB
	   $VMCount = $CloudUsage.VMUsageCount
	   [int]$NewCPUCount = [int]$CPUCount + 40;
	   [int]$NewMemory = [int]$Memory + 81920;
	   [int]$NewVMCount = [int]$VMCount + 10;
	   Get-SCUserRoleQuota -UserRole $UserRole -Cloud $MyCloud | Set-SCUserRoleQuota -CPUCount $NewCPUCount -MemoryMB $NewMemory -VMCount $NewVMCount
	}
}

That will set on all profiles on $UserRoles array.
