The disk is offline because of policy set by an administrator
Just spun up Hyper-V and five VMs running Wndows Server 2008 R2. Rock solid so far, everythng just works -except- when I plug in my 1TB IOMEGA eSATA drive the O/S sees it but it remains offline. I get:
"The disk is offline because of policy set by an administrator". I have read and read but nowhere can I find how to allow this in group policy or wherever. Please advise. Thanks!

If your Hyper v is part of a domain, it recieves a GPO which is configured by the domain admins. Try using the GPO editor so see wether or not you can change settings. If you have a standalone server you should not have this problem. But if for some reason you do you should check the local security settings.
Okay. Could you please get a little more specifc? I will check whatever you suggest, but where do I start?
I have the same problem. Windows Server 2k8 VM sees the disk created with the VM fine. Added a second disk to the server and it shows in Disk Manager as offline with the same message. This is happening on VMs that are not part of the domain so no domain policy is being applied to the server. Any advice is appreciated.

Well i guess it was a bit of confusion along with the problem description and provided solution. If you add another disk to the computer, you have to bring it online using diskmgmt.msc you can type this in run or just goto control panel and open disk management. As jayatcarico is describing it should solve the problem.
I will give both steps a try first thing in the morning. I will keep all VM's down and start with the base install. I cannot remote in or I would do it now... firewall ports shut until we get a new firewall.
Okay, I did not realize that I had to manually bring them online. I am curious, will I have to do this every time I plug them in? I will test and post a comment. BTW, I did not need to format or initialize or anything like that. I simply brought them online and dragged a 7GB file from the internal hard drive. Worked like a champ.

The disks now stay online even when I power off the VMs and the host server. Not sure why MSFT would issue such a message... I was digging around looking for a policy, etc. I am good to go now, just right click and tell them to on online. Good as gold.
