Azure VHD Upload Fails “An upload is already in progress on machine HOSTNAME with process ID”

Uploading VHD’s to an Azure Storage Account is straight forward, the following command;
Add-AzureVHD -Destination https://storageaccountcontainer -LocationFilePath “C:\Win7.vhd”
You must create your Storage Account and relevant containers prior to running the command. I tried to upload a VHD, which failed to complete successfully this was due to a network connectivity issue on the client uploading the VHD file.
I tried to run the command again and received the following error “An upload is already in progress on machine HOSTNAME with process ID” even though I knew it had failed.

The fix here was to manually delete the partially uploaded VHD file. This can be done using the Web-GUI if you enter the Container that the original VHD select it and Delete the disk.

Run the Azure command again and the VHD should begin uploading again.
