Robocopy Fails on Windows Cluster Shared Volumes (CSV)

Using Windows 7 client, or Windows server 2012 r2 Hyper-V console on a cluster node, robocopy fails to copy files from a CSV to a client share.

Either using Windows Explorer or XCopy works, however XCopy failed on files over 2GB... So lets go old school for the VXD copy.

Changing MAC Address on Hyper-V and routing fails

With a traditional computer, running Windows, you can simply go to the network card, change the MAC address and everything works as expected. 

But recently I did this on a Hyper-V server in a SCVMM network and while it would work correctly on the local subnet it could not route to a adjacent connected network. I would fail to ping the remote router.

So to correct this make sure you update the MAC Address in SCVMM computer object.

Hyper-V media disconnection

Got an issue with Hyper-V servers connected to media?

Run this.

[string[]]$cn = Get-ADComputer -Filter * -SearchBase 'OU=Hypervisors,OU=Services,DC=internal' | select -ExpandProperty dnshostname

$vm = Get-VM -ComputerName $cn -Name *

$vm | Get-VMDvdDrive | ? DvdMediaType -ne None | Set-VMDvdDrive -Path:$null
