We have the need to connect an existing USB hard drives containing our SBS 2008 backups to an existing Hyper-V Server 2008 R2 box using the new USB HDD pass through feature.
To do so requires three things to be done. One on the remotely connecting management machine and two on the Hyper-V box itself.
On the management machine:
- Click Start –> Firewall Advanced [Enter]
- The Windows Firewall with Advanced Security console should come up after a UAC.
- Remote Volume Management - Virtual Disk Service (RPC)
- Remote Volume Management - Virtual Disk Service Loader (RPC)
- Remote Volume Management (RPC-EPMAP)
On the Server Core box repeat the above but also make sure of the following:
- The Virtual Disk service is set to Automatic.
Once the three steps above have been completed, we are now able to remotely manage the volumes on the Hyper-V box thus enabling us to place those USB HDDs Offline to allow VM access in the Hyper-V Manager:
Thanks to Sander Berkouwer & Joachim Nässlander:
Slide #9 indicates that _both_ the management and Server Core boxes need the firewall exception which was our initial stumbling point on getting things working.
