Windows Server 2012 Logical Disk Free Space (%) Low

Question

I enabled the monitor "Windows Server 2012 Logical Disk Free Space (%) Low" and configured a low threshold to test. I started to get a bunch of warnings from servers, for example:
The disk \\?\Volume{ee0222ed-16de-40a5-af89-f95db3fdf5a4} on computer PC is running out of disk space. The value that exceeded the threshold is 11% free space.
Now I checked on the server, and all the disks have more than 11% free space. Additionally, I don't see any disks with such a name/guid.
When looking at the additional knowledge of the monitor, I see that it is using the following information:
Object Name: Logical Disk
Counter Name: PercentFree 
My question is where is this disk coming from, and how can I avoid these disks from creating false alarms? When looking in the Windows Server
From my analyzing the DB, I see that these are the partitions on the server without a volume letter. Any way to avoid getting these discovered and/or alerts, without overriding each one?

Hi,
These "strange" disks are called mount points.
They get discovered by the "Mount Point Discovery Rule".
Go to your authoring => rules => search for the rule above and disable it.
If you want to remove all the instances in your environment you need to use Remove-SCOMDisabledClassInstance
powershell cmdlet.
More info on the cmdlet can be found here:  http://technet.microsoft.com/en-us/library/hh920257%28v=sc.20%29.aspx
