I have two W2k8 R2 servers built together with similar configurations. BitLocker has been enabled on both servers. One server displays OS drive as a hard disk drive and the data LUNs under the Bitlocker To Go section of the BitLocker control panel app. The other displays only the OS drive and no data LUNs. I run manage-bde -status on the first server and I get a list of the data luns. On the second, I get the following:
C:\Windows\system32>manage-bde -status
BitLocker Drive Encryption: Configuration Tool version 6.1.7601
Copyright (C) Microsoft Corporation. All rights reserved.
ERROR: There are no disk volumes that can be protected with BitLocker Drive
Encryption.
NOTE: In pre-installation or recovery environments, decrypted volumes are not
displayed.
I've restarted the server, uninstalled and reinstalled bitlocker with associated restarts. The status doesn't change.
There are a couple similar posts but they have not provided any conclusive resolutive actions:

Bitlocker Can't enumerate, associated data is missing

How can I get the LUNs to enumerate?
