These steps below will help you to tune the \\?\Volume ID from being discovered or monitored for disk space.
Alerts showing in the Console:
Create a new Dynamic or Static Override Group to look for \\?\Volume and exclude this from monitoring:
1. From the Authoring View, right click Groups, ‘Create New Group’
2. Name the Group a name in which you can easily identify where the Overrides are Targeted
· I used ‘Disk Monitor Disabled Override Group’ or you could use \\?\Volume in the name
· Create an Override Groups MP and save the New Group in this MP
4. To Create a Dynamic Group (Do not use the Explicit Members option): at the Dynamic Members page, click New, then Insert the property for the following and click OK:
· AND group for Logical Disk (all of these are true)
· Display Name – Contains – \\?\Volume
5. Create an Override to target the new Group you created above
· Monitor Name – Windows Server 2008 Logical Disk Free Space (MB) Low
· Override the Enabled Value, and click Enforced
7. Right click the Mount Point Discovery rule, click Override > Override for Group, then Click Override, False , Enforced, click OK
