Powershell script to install Nasuni Filer on Windows Hyper-V 2012 R2

Nasuni provides managed storage service that offers interesting functionality in the cloud integrated storage space. The Nasuni Filer Virtualization Guide suggests to import the Nasuni Filer VM from the unzipped files from filer-hyperv-6.1.1-99.zip. Before using this script you need to obtain the Filer.vhd file – see this post for more details.

This script automates and streamlines the process of installing the Nasuni Filer Virtual Machine on Hyper-V 2012 R2. It can be downloaded from the Microsoft Script Center Repository.

In this example,

  • I’ve stored the script as \\rd06\scripts$\Install-Nasuni-Filer.ps1
  • I’m running the script on a Hyper-V host
  • I will storing the VM files under C:\ClusterStorage\Volume1 – this can be any local path on the Hyper-V host
  • The path for the needed Filer.vhd file is \\rd06\d$\Nasuni\Filer.vhd
  • In this particular environment, guest networking is on VLAN 5. If you’re not using VLANs you can omit this parameter
  • I will call this VM “Nasuni-Demo2”

Dot source the script with parameters similar to:

. \\rd06\scripts$\Install-Nasuni-Filer.ps1 -VMPath C:\ClusterStorage\Volume1 -VHDPath \\rd06\d$\Nasuni\Filer.vhd -VLAN 5 -VMName Nasuni-Demo2


The script creates a subfolder with the VM name under the VMPath

It converts the Filer.vhd to VHDX format. VHDX format has many performance and other enhancements over VHD.

It creates the Nasuni Filer VM as Gen 1 VM.

It detects the host’s first external vSwitch and attaches the VM vNIC to it. If you have more than 1 external vSwitch on this Hyper-V host, you can spell out which one to use in the command line by using the -vSwitch parameter

It sets the VM startup memory to 6GB as recommended by the Nasuni Filer Virtualization Guide.

It assigns the VM 4 CPU vCores. This can be adjusted by the optional parameter -ProcessorCount

It sets VM automatic start action to “start”. This ensures the VM is started when the host is rebooted.

It sets the VM memory to static. This VM does not have the Hyper-V Linux Integration Service and cannot use dynamic memory.

It assigns the VM vNIC a static MAC address. This is necessary for live-migration. Otherwise the VM will lose its IP settings when live-migrated.

It assigns the vNIC VLAN ID if the -VLAN parameter is used

It creates and adds the Cache.vhdx and COW.vhdx disks and attaches them to the VM. They’re attached to SCSI controller 0 / LUN 0, and controller 1 / LUN 1. This is to mirror setup suggested by Nasuni. It’s not clear why the Cow.vhdx disk needs to be on a separate SCSI controller or why it needs LUN 1 specifically. By default, the second SCSI disk added will go on controller 0 / LUN 1.

Finally the script starts the VM.


As usual, the script leave a log file behind on the folder where it ran. Log file lists steps taken and will look like:

After VM installation, go to Hyper-V Manager:


Open the VM console, you’ll see display similar to:


In this example, I have DHCP server running on the network. The Nasuni Filer VM obtained an IP address via DHCP as shown.

If no DHCP server is running on the network, assign IP address to the Nasuni Filer VM by using the following commands:

  • Hit enter to enter the Service Menu, login as service, password is serviceNasuni010
  •  Type in the following commands:Nasuni010
    • editnetwork
    • setall static
  • Enter the desired IP information for the VM.
  • Type in “save” to save settings
  • Type in “close” to exit the Service Menu

Browse to the IP address of the Nasuni Filer to complete setup. Bypass the certificate security warning. Nasuni-HyperV9

Enter/confirm IP settings.

Nasuni-HyperV10Click on the Edit button next to the Ethernet 1 device to update its IP info. Enter 9000 for MTU if using jumbo frames.


Review and continue. Nasuni-HyperV12Click Continue to save settings. Nasuni-HyperV13

Enter Serial Number and Authorization code. In the email from Nasui, there will be a link and credentials to obtain these. Nasuni-HyperV14

Type in “confirm” to confirm, and check the box to accept the EULA. Confirm/edit the name for this Nasuni Filer. Nasuni-HyperV15

If you already have the Nasuni Management Console (VM) deployed, you’ll get this screen:Nasuni-HyperV16

Check the box to manage this Filer under the central NMC.

Enter/create admin credentials for this Filer. Nasuni-HyperV17
