You can get VMs with vHBA on Hyper-V Cluster via this PowerShell script:

Get-Cluster | Get-ClusterNode | % {Get-VM -ComputerName $_.Name | Where {(($_ | Select -expand FibreChannelHostBusAdapters) -ne $Null)}} | ft Name, ComputerName, State

You should run your PowerShell as Administrator.

You should run this script on Cluster node. Migrates all VM online.

You should run this script on Cluster node. Migrates all VM by shutting down first.

You can get VMs with Passthrough disks and vHBA on Hyper-V Cluster via this PowerShell script:

Get-Cluster | Get-ClusterNode | % {Get-VM -ComputerName $_.Name | Where {(($_ | Select -Expand HardDrives).Path -like "Disk*") -or (($_ | Select -expand FibreChannelHostBusAdapters) -ne $Null)}}

You should run your PowerShell as Administrator.

Sonunda bir hayattan.. yazısı daha. Bu aralar iş yoğunluğu nedeniyle artık blogta sosyal hayattan paylaşımlar yapamayacak duruma gelmiştim. Bunda belki biraz da Facebook’un çok daha basit bir paylaşım platformu olması ve bloguma oranla çok daha fazla kişiye hızlı bir şekilde ulaşıyor olmasından da kaynaklanıyor olabilir :) Bu durum da blogumda daha çok PowerShell içerikli scriptlerin eklenmesine sebep oluyordu :) Fakat uzun bir aradan sonra tekrar bana ait bir blog yazısıyla buradayım. Son “hayattan” kategorisindeki yazımı, 11 Kasım 2012’de Londra notlarım olarak eklemişim. Yeni yazı ile birlikte de sosyal paylaşımlarımı sürdürmeye karar verdim :)

15 Eylül’de yapılan ÇözümPark yazar toplantısında, Webcast dalında yılın yazarı seçildiğim söylenerek güzel bir sürprizle karşılaştım :) Sağolsunlar güzel bir plaket ve sertifika ile taçlandırmışlar bu güzel ödülü. Çok onurlandım ve duygulandım :) Microsoft Türkiye’de gerçekleşen harika etkinlikten bana kalan (süper bir hediye, plaket ve sertifika dışında :)) aşağıdaki güzel kareler oldu :)

Yılın yazarı hediyesi olarak verilen süper cihazı ise burada paylaşmıyorum :) Sonuçta plaket ve sertifikanın benim için değeri çok daha fazlaydı :)

You can get WWN information from servers like this:

3
4
5

7
$Servers = "VMHOST01","VMHOST02","VMHOST03","VMHOST04"
Foreach ($Server in $Servers)
{
	Write-Host $Server
	Invoke-Command -ComputerName $Server -ScriptBlock {&C:\StorageTools\fcinfo\fcinfo}
	Write-Host " "
}

You must deploy fcinfo.exe to hosts before you execute this script. You may also use WMI to get WWNs.

# Getting Disk Signature
Get-WmiObject Win32_DiskDrive | ft Name, Signature, Index
 
# Add Disk Signatures into Array
$Signatures = "650992792","650992689"
 
# Making Them Online
foreach ($Signature in $Signatures)
{
	$Disk = Get-WmiObject Win32_DiskDrive | Where {$_.Signature -eq $Signature}
	$DiskID = $Disk.index
	$DiskPartScript = @"
select disk $DiskID
online disk noerr
"@
	$DiskPartScript | diskpart	
}
 
# Making Them Offline
foreach ($Signature in $Signatures)
{
	$Disk = Get-WmiObject Win32_DiskDrive | Where {$_.Signature -eq $Signature}
	$DiskID = $Disk.index
	$DiskPartScript = @"
select disk $DiskID
offline disk noerr
"@
	$DiskPartScript | diskpart	
}

Get-Disk is not available in Windows Server 2008 R2, so you should go with WMI.
