    Hi everyone ,

                Am new to virtualization , I have a windows server 2012 hyper-v server, I had successfully created the VM with windows server 2008 R2 as per my client requirement. In that VM I want to attach a VHD for storage inside the VM.For that I had turned off the VM and I had attached the VHD ,in that it attached successfully but when I started the VM the VHD displays but not accessible for use , it is not able to format also hitting the error "this process cannot proceed at this time, another process is running". I had checked all the background process but no solution also I had tried VHDX but yet I did not able to access this disk in VM in hyper-V 2012 .

             please help !!!

    Hi Sir,

    >>I have a windows server 2012 hyper-v server, I had successfully created the VM with windows server 2008 R2 as per my client requirement.

    >>In that VM I want to attach a VHD for storage inside the VM.For that I had turned off the VM and I had attached the VHD

    Please try to creat a new VHD file on server 2012 hyper-v Local Drive then try to attach it and check the result .

    In addition , If there is any Anti-Virus software installed please disable it .

    If the issue persists , you can try to create a new VM attach a new VHD file to narrow it down .

    Best Regards,

    It is not clear as to how you are going about the process.

    However the normal process for creating a VM with additional drives would be as follows.

    If you are creating a Generation 1 VM then your "C:" drive or first vhdx file would be attached using the first IDE. For performance reasons you will want to create a new VHDX and connect it to the SCSI controller.  Then when you boot up the VM you can initialize and format the drive from within the VM. 

    For a generation 2 VM every disk is connected to SCSI.

    Always use VHDX unless you plan to move the VM to Azure.

    Did you open disk management inside of the VM and scan for changes and bring the disk online?

    Attaching a second virtual disk as a data disk is pretty straightforward.

    Also, did you update the Integration Components within the VM after you installed the OS?

    I had Run the Integration Components Services and I had also tried to Initialize disk inside the VM and I had got the Error that  "the process cannot access the file because it is being used by another process"
