Azure Resource Manager (ARM) : Move VM storage

Hi All,

I`ve been working on a new hosting platform in Azure Resource Manager(ARM) for a new customer of ours.
After some weeks of deploying VM`s we came to the conclusion that using only one storage account for the VM`s wan`t the way to go. So we decided that we had to split up the storage.
This is when we found out that there isn`t an easy way to move the VM storage. 
To move/copy the VM storage you need to perform the following steps:

- Stop the VM
- Save the VM config
- Copy the blob`s from one storage account to the other
- Edit the VM config
- Remove the current VM
- And recreate the VM using the saved config

But we`ve had already deployed 21 VM`s so i decided to create a powershell function and script to do this.
And here it is for the people who face similar problem or just don`t want to go through the hassle of finding out how to move the storage  :-) :

function Copy-AzureVMStorage($vmName, $resourceGroup, $oldStorageContext, $newStorageContext, $srcContainer, $dstContainer, $location)
{
 #Retrieve VM Config
 try
 {
  $vm = Get-AzureVM -ResourceGroupName $resourceGroup -Name $vmName
  
   if($vm -eq $null)
   {
    return
   }
 }
 catch
 {
  return
 }

 #Check if container exists in destination storage account
 $container = Get-AzureStorageContainer -Name $dstContainer -Context $newStorageContext -ErrorAction Ignore
 if($container -eq $null)
 {
  New-AzureStorageContainer -Name $dstContainer -Context $newStorageContext
 }
 
 #Stop the VM
 Stop-AzureVM -ResourceGroupName $resourceGroup -Name $vmName -Force
 
 #Copy the vhd`s to their new location
 try
 {
  $osDiskVHD = $vm.StorageProfile.OSDisk.Name + ".vhd"
  $copy = Start-AzureStorageBlobCopy -SrcBlob $osDiskVHD -SrcContainer $srcContainer -DestContainer $dstContainer -DestBlob $osDiskVHD -Context $oldStorageContext -DestContext $newStorageContext -Force
  Get-AzureStorageBlobCopyState -Container $dstContainer -Blob $copy.Name -Context $copy.Context -WaitForComplete
  $newOSDiskEndPoint = $newStorageContext.BlobEndPoint + $dstContainer + "/" + $osDiskVHD
  if($vm.StorageProfile.OSDisk.OperatingSystemType -eq "Linux")
  {
   Set-AzureVMOSDisk -VM $vm -Name $vm.StorageProfile.OSDisk.Name -VhdUri $newOSDiskEndPoint.Replace("https://", "http://") -CreateOption attach -Linux
  }
  else
  {
   Set-AzureVMOSDisk -VM $vm -Name $vm.StorageProfile.OSDisk.Name -VhdUri $newOSDiskEndPoint.Replace("https://", "http://") -CreateOption attach -Windows
  }
  
  foreach($dataDisk in $vm.StorageProfile.DataDisks)
  {
   $dataDiskVHD = $dataDisk.Name + ".vhd"
   $copy = Start-AzureStorageBlobCopy -SrcBlob $dataDiskVHD -SrcContainer $srcContainer -DestContainer $dstContainer -DestBlob $dataDiskVHD -Context $oldStorageContext -DestContext $newStorageContext -Force
   Get-AzureStorageBlobCopyState -Container $dstContainer -Blob $copy.Name -Context $copy.Context -WaitForComplete
   $newDataDiskEndPoint = $newStorageContext.BlobEndPoint + $dstContainer + "/" + $dataDiskVHD
   Remove-AzureVMDataDisk -VM $vm -DataDiskNames $dataDisk.Name
   Add-AzureVMDataDisk -VM $vm -Name $dataDisk.Name -VhdUri $newDataDiskEndPoint.Replace("https://", "http://") -Lun $dataDisk.Lun -CreateOption attach -DiskSizeInGB $dataDisk.DiskSizeGB
  }
 }
 catch
 {
  return
 }
 
 #Clean up the VM config before recreating
 $vm.StorageProfile.ImageReference = $null
 $vm.OSProfile = $null
 
 #Recreate VM
 Remove-AzureVM -ResourceGroupName $resourceGroup -Name $vmName -Force
 New-AzureVM -ResourceGroupName $resourceGroup -Location $location -VM $vm
}

#Setup connection to ARM
Add-AzureAccount
Switch-AzureMode -Name AzureResourceManager
Select-AzureSubscription -SubscriptionName "Contoso Subscription"

#Define storage accounts
$oldstoragecontext = New-AzureStorageContext -StorageAccountName "ContosoOld" -StorageAccountKey "<KEY>"
$newstoragecontext = New-AzureStorageContext -StorageAccountName "ContosoNew" -StorageAccountKey "<KEY>"

#Copy the VM storage and edit its config
Copy-AzureVMStorage "ContosoVM" "ContosoGroup" $oldstoragecontext $newstoragecontext "vhds" "vhds" "westeurope"

SFTP in PowerShell

Hi All,

A while ago we where migrating customers from our old FTP server to our brand new SFTP server :-)
But one of those customers had an automated script(PowerShell) in place uploading files during the night.
So we where searching for an solution to script SFTP uploads(which wasn't easy).
There are a few payed solutions for implementing SFTP capability`s in PowerShell and you can also use application like WinSCP to "fake" SFTP capability`s.
But i thought it would be nice if someone created an free PowerShell Snap-In that implements SFTP capability`s.

At this point I went in search for an open-source SFTP implementation for C#, I came across an open-source library that I used before(SharpSSH).
This library was the perfect candidate to embed in the PowerShell Snap-In.
So after some coding this was what i came up with : Download SFTP PowerShell Snap-In

I can present this Snap-In to you with many thanks to Tamir Gal and Will Fitch, these two guy`s created the great SharpSSH library on which the Snap-In is based !

Kind Regards,
Kevin

P.S.
Sample scripts to show you how the Snap-In works are included in the zip file. ;-)


==== UPDATE-2 16-4-2012 =====
Hi All,

I`m now in the testing phase of version 2 of the Snap-In.
Who would like to help and test it ?
You can download the v2-beta here !
There now is an extra CmdLet named Open-SFTPServerWithPublicKey which as the obvious name states allows you to authenticate with a public private key pair :-)
Please note that the private key must be in OpenSSH format and you must provide the full path to the file!

==== UPDATE 16-4-2012 =====
Hi All,

I uploaded a new version of the Snap-In, lets call it uhmmm v1.3 :-)
It includes port selection and PowerShell 3 support.
To get PowerShell 3 support i had to update the installer to include the right InstallUtil(With thanks to Rich Harrington).


==== UPDATE 15-4-2012 =====
Hi All,

I`m currently working on version 2 of the snap-in.
It`s going to include support for public-key authentication.
If there are any other feature requests please leave a comment.
