SCOM 2012 R2 Data Warehouse woes...

Hello all.
 
I'm currently running a single Management Server deployment of SCOM 2012 R2.  70 servers monitored, no distributed apps or anything fancy like that.  I've been getting a ton of errors related to the Data Warehouse.  After attempting multiple resolutions, I've decided that the easiest path will be to rebuild the Data Warehouse from the ground up.  We're not worried about losing data.
 
A GlobalKnowledge instructor told me that the easiest method might be to simply rename the existing database, then to create a new one named the same as the old one.
 
If anyone has any insight on this, I would appreciate it.  I would greatly prefer to not have to start completely over with my SCOM deployment if at all possible, and I'm not enough of a DBA to know whether the database can be fixed.  I did try to run a DBCC on it, which fails.

What does the DBCC CheckDB show.
Try CHECKDB ('database_name') WITH NO_INFOMSGS, ALL_ERRORMSGS
Let it finish, and post your errors here as a text file.

No results returned, just the below messages:

Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command.  The results, if any, should be discarded.
Msg 0, Level 20, State 0, Line 0
A severe error occurred on the current command.  The results, if any, should be discarded.

I'm sorry to say that you most likely had a failure of hardware. Probably a disk outage.
Your database seems corrupt.

Now it's time to pull foreward your DR plan. I e, what do we loose in form of transaction if we use the backup/restore plans that you hopefully have designed. Compared to what your potential loss is if you determine to attempt a repair, allowing dataloss.

Time is a factor. A repair can be very timeconsuming. And given your DBCC reply code, it might not even be possible.

will give some inputs.

Please understand, a restore will not make your day, even if this is acceptable or even good regarding to the data, you need to pursuit the root cause. If you do not you will be hit again and again. It's time to analyze eventlogs and errorlogs. Maybe even send stack dumps to Microsoft. Don't skip this step.
