Question : Script adding / removing SCSI passthrough drive in Hyper-V R2

Can someone help me with a script (so I can schedule it) to make Hyper-V R2 add / remove a drive attached to a Hyper-V host (assume it is offline in the host) to an existing VM (whish has an existing virtual SCSI controller) in Windows 2008 R2?

Of course the other part to take the drive offline in the host OS would also be helpful.

HyperV_Install.zip is the actual module, you will need to install
PShyperv-R2.pdf is the documentation with examples on how to use it.
