Reporting doesn't show the newly installed SCOM Agents

Question

Hello,
I am running SCOM 2012 SP1 on Win2008 R2.
I recently deployed scom agent to couple of machines the agents are showing up healthy and i can see the performance and health data from Monitoring tab but when i try to run report i can't find these new agents in the objects to add to report.
Report
it doesn't even query the agents.
and on the SCOM manamgent server i see this error in event viewer not sure if it is related.
Data was written to the Data Warehouse staging area but processing failed on one of the subsequent operations.
Exception 'SqlException': Sql execution failed. Error 2627, Level 14, State 1, Procedure ManagedEntityChange, Line 368, Message: Violation of UNIQUE KEY constraint 'UN_ManagedEntityProperty_ManagedEntityRowIdFromDAteTime'. Cannot insert duplicate key in object
'dbo.ManagedEntityProperty'. The duplicate key value is (528, Aug 25 2013  8:52AM). 
One or more workflows were affected by this.  
Workflow name: Microsoft.SystemCenter.DataWarehouse.Synchronization.ManagedEntity 
Instance name: 08eb00a2-e227-4472-a368-a6e42a2bc502 
Instance ID: {EEFCB078-6517-97CD-FA4F-8FCAB54E4930}

Ok, so at this point, without enabling logging and going to the extremes, I would attempt an uninstall and reinstall of the agents.  One at a time.  So remove the agents.  Reinstall one, and monitor what is happening on that server, and investagate
it in the ops console.
If you know what applications are on the box, and being discovered, look for the server in discovered inventory for those classes, etc.
Before you do that, you can try to run this against the DW to see if there are any alerts associated with these two servers, that is if they ever raised alerts:
USE OperationsManagerDW
SELECT Alerts.AlertName, SUM(1) AS 'Alert Instances', SUM(Alerts.RepeatCount + 1) AS 'Alert + Repeat Count',
CASE Alerts.MonitorAlertInd WHEN 1 THEN vMonitor.MonitorDefaultName WHEN 0 THEN vRule.RuleDefaultName ELSE 'Not found' END AS 'Rule or Monitor Name',
CASE Alerts.MonitorAlertInd WHEN 1 THEN 'Monitor' WHEN 0 THEN 'Rule' ELSE 'Not Found' END AS 'Rule or Monitor', vManagedEntity.Path,
vManagedEntity.DisplayName
FROM Alert.vAlert AS Alerts INNER JOIN
vManagedEntity ON Alerts.ManagedEntityRowId = vManagedEntity.ManagedEntityRowId LEFT OUTER JOIN
vRule AS vRule ON Alerts.WorkflowRowId = vRule.RuleRowId LEFT OUTER JOIN
vMonitor AS vMonitor ON Alerts.WorkflowRowId = vMonitor.MonitorRowId
WHERE (Alerts.RaisedDateTime BETWEEN DATEADD(day, - 180, GETDATE()) AND GETDATE()) AND
(Alerts.AlertName like '%Hub Servers In Retry Error%') and path like '%servername%'
GROUP BY Alerts.AlertName, Alerts.MonitorAlertInd, vMonitor.MonitorDefaultName, vRule.RuleDefaultName, vManagedEntity.Path, vManagedEntity.DisplayName
ORDER BY 'Alert Instances' DESC
