Secure Password Usage in PowerShell

Posted in Windows Powershell | 1 Comment | 2,465 views | 31/07/2013 16:48

If you need to store a secure password in PowerShell, you can use this process.

First, you should create a hash from your password:

1
2
3

$Key = (3,4,2,3,56,34,254,222,1,1,2,23,42,54,33,233,1,34,2,7,6,5,35,43)
$SecureString = ConvertTo-SecureString "Your_Password" -AsPlainText -Force
$StandardString = ConvertFrom-SecureString $SecureString -Key $Key

After that you can use $StandarString output in your scripts. Just you need to convert it back to secure string:

1 2	$Key = (3,4,2,3,56,34,254,222,1,1,2,23,42,54,33,233,1,34,2,7,6,5,35,43) $SecureString = ConvertTo-SecureString $StandardString -Key $Key

That’s it. I hope that helps.

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

Posted in Virtual Machine Manager, Windows Powershell, Windows Server | No Comment | 2,456 views | 26/07/2013 15:56

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

$UserRoles = "BackOffice","CallCenter","ExchangeTeam"
foreach ($UserRole in $UserRoles)
{
	$UserRole = Get-SCUserRole $UserRole
	$Clouds = "DMZ Cloud","Prod Cloud","Test Cloud"
	foreach ($Cloud in $Clouds)
	{
		$MyCloud = Get-SCCloud $Cloud
		$CPUCount = (Get-VM -Cloud $MyCloud | Where UserRole -like "$UserRole" | Measure-Object -Property CPUCount -Sum).Sum
		$Memory = (Get-VM -Cloud $MyCloud | Where UserRole -like "$UserRole" | Measure-Object -Property Memory -Sum).Sum
		$VMCount = (Get-VM -Cloud $MyCloud | Where UserRole -like "$UserRole").Count
		[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.

Changing UserRole of some Virtual Machines on SCVMM 2012 SP1

Posted in Virtual Machine Manager, Windows Powershell, Windows Server | No Comment | 2,443 views | 26/07/2013 12:06

You can change UserRoles of virtual machines on SCVMM 2012 SP1 with following command:

$VMs = Get-VM | Where Name -like "*CALL*" | Where UserRole -eq $Null
foreach ($VM in $VMs)
{
	$UserRole = Get-SCUserRole "MyUserRole"
	$VM | Set-VM -Owner "DOMAIN\Owner" -UserRole $UserRole
}

That will only change “null” user roles. If you want to change existing user roles:

$VMs = Get-VM | Where Name -like "*CALL*" | Where UserRole -like "OldUserRole"
foreach ($VM in $VMs)
{
	$UserRole = Get-SCUserRole "NewUserRole"
	$VM | Set-VM -Owner "DOMAIN\Owner" -UserRole $UserRole
}

It will only looks for VMs like “CALL”. You can leave it blank for all virtual machines.

You can get total CPU and memory usage of a user role with following command:

That will give you total count of cpu and memory.

Posted in Windows Powershell, Windows Server | No Comment | 1,765 views | 18/07/2013 10:10

You can get DNs of your servers with following PowerShell script:

$DomainServers = Get-ADComputer -Filter *
$ChildDomainServers = Get-ADComputer -Filter * -SearchBase "DC=child,DC=domain,DC=com" -Server "child.domain.com"
$Servers = Get-Content C:\Servers.txt
foreach ($Server in $Servers)
{
	$DN = $null;
	$DN = ($DomainServers | where DNSHostName -eq "$Server").DistinguishedName
	if (!$DN)
	{
		$DN = ($ChildDomainServers | where DNSHostName -eq "$Server").DistinguishedName
		if (!$DN)
		{
			Add-Content -Value $Server -Path C:\DNs.txt
		}
		else
		{
			Add-Content -Value $DN -Path C:\DNs.txt
		}
	}
	else
	{
		Add-Content -Value $DN -Path C:\DNs.txt		
	}
}

You should add your server list into C:\Servers.txt.

Getting Hyper-V Failover Clusters List via PowerShell

Posted in Virtual Machine Manager, Windows Powershell, Windows Server | 1 Comment | 3,570 views | 16/07/2013 09:23

You can get Cluster names from your Hyper-V host list with following PowerShell script:

# Prepare Cluster Array
$ClusterArray = New-Object System.Collections.ArrayList
$Servers = Get-Content -Path C:\Servers.txt
foreach ($Server in $Servers)
{
	$VMHost = Get-VMHost -ComputerName $Server
	$HyperVFQDN = $VMHost.FullyQualifiedDomainName
	if ($VMHost)
	{
		$ClusterName = (@(Get-Cluster $Server | Get-ClusterGroup | where GroupType -eq "VirtualMachine") | Select-Object -First 1).Cluster.Name
		if ($ClusterName)
		{
			$TestCluster = $ClusterArray.Contains("$ClusterName")
 
			if ($TestCluster -ne $True)
			{
				# Update Cluster Array
				$ClusterArray.Add("$ClusterName") | Out-Null
			}
 
			Write-Host $ClusterName
		}
	}
}

After that you can use your Cluster names to get CSV reports.
