Virtual disks under Storage Spaces won’t stay attached after reboot!

Few days ago friend of mine asked me if I know how to fix this issue and I succeeded. Now I want to share with all of you.
The scenario is as follows…

Windows Server 2012 R2, one Storage Pool, few virtual disks. The behavior starts to happen after Windows Server 2012 R2 re-installation. Everything was fine until restart. Virtual Disks are present and attached but after restart the server they are detached.

If you are looking under virtual disk Properties/Details/Property (look picture below) you will notice that IsManualAttach – Value is True. In other words, if you want virtual disk be attached you must do manually attach.

Resolution

Open PowerShell as administrator, type as follows and press Enter

Set-virtualdisk -FriendlyName <VirtualDiskName> -IsManualAttach $false

10

Refresh Server Manager Console and you Virtual Disks will be attached. After you restart your server Virtual Disks still be attached ;)

I wish you all the best in 2014!

Enjoy the day :)

Convert single VMware virtual disk (.vmdk) to Hyper-V virtual disk (.vhd) with Microsoft Virtual Machine Converter (MVMC)

In this blog post I’ll explain how to convert .vmdk to .vhd and how to create new Hyper-V virtual machine with converted disk.
What is Microsoft Virtual Machine Converter (MVMC)? The Microsoft Virtual Machine Converter Solution Accelerator is a stand-alone solution for the IT Pro or solution provider who wants to convert VMware based virtual machines to Hyper-V based virtual machines. The MVMC solution can perform full conversion of VMware based virtual machines as well as conversions of VMware virtual disks to Hyper-V virtual disks.
Supported & Free – Quick and easy to download, use and start conversions of VMware VMs
Convert to 2012 – Converts and deploys virtual machines or virtual disks from VMware to Hyper-V hosts including Hyper-V on Windows Server 2012
Scriptable –  Fully scriptable command-line interfaces for performing virtual machine and disk conversions that integrates well with data center automation workflows and Windows PowerShell scripts

With a GUI we can convert VMware based VMs only if have vCenter server, ESX server, or ESXi server.

But, what if I have VMware workstation based VMs? Can I convert these VMs? NO, we can’t convert these VMs on that way but can convert virtual disks (.vmdk) (with CLI) and then can create new VM in Hyper-V.
So, this is detailed how to…

Step 1. Convert .vmdk to .vhd
Open command prompt as administrator and navigate to

C:\Program Files (x86)\Microsoft Virtual Machine Converter Solution Accelerator>mvdc.exe “sourcedisk\vmdkdisk\vmdisk.vmdk” “destinationdisk\newvhddisk\newvhd.vhd” press Enter.

Step 2. Create Hyper-V virtual machine with converted virtual disk

And voila, we have Hyper-V virtual machine up & running ;)

MVMC Capabilities

  • Converts VMware VMs to Hyper-V VMs
  • Supports converting to WS2012 Hyper-V
  • Wizard Driven UI for conversion
  • Includes CLI for VM and virtual disk conversion
  • Supports offline conversion of .vmdk to .vhd
  • Removes VMware tools for a clean migration
  • Installs Hyper-V integration services

This isn’t only way for conversion, we can do that in a few ways, but it is one of the simplest.

Enjoy the day!
