Does anyone knows wich discovery populates the Microsoft.Windows.Server.Computer class property "Is Virtual Node"? SCOM does not discover the operating system of a server because the property "Is Virtual Node" is set to True. This machine is not a virtual node but the server name was used in the past as a virtual node that was deleted months ago. For some reason, SCOM retained the information and when the machine was discovered (this week) the property "Is Virtual Node" was set to True! There is any way to change the property value? Thank You.

Hi, Please check if any information as below will help: Your MP Discoveries and Clustering http://blogs.technet.com/b/authormps/archive/2011/03/13/your-mp-discoveries-and-clustering.aspx Service Monitor for Cluster http://social.technet.microsoft.com/Forums/en-US/operationsmanagerauthoring/thread/ea5237ad-d2f1-4e1a-863a-6d6d46b7d459/Vivian Xing TechNet Community Support

the discovery which populates this property never sets false for it. Property either empty or set to true by the discovery. i think the easiest supported way for you is to remove agent, wait two days until SCOM grooms marked for deletion records, then install agent back next supported option is to author custom discovery which resets this property to null, enable discovery only for your object. direct DB editing. UNSUPPORTED. your table dbo.MT_Computer_1. join it with dbo.BaseManagedEntity to get computer name.

Hi, if you can provide as more information about your problem and to understand you're talking about a cluster and if I understood well you have a physical node that was a virtual node?Oussama Oueslati | System Engineer | vNext Consulting

Hello, I removed the agent but the server remained within the Monitoring/"Windows Computers" View with a greyed out state. The result of the query: SELECT * FROM dbo.[BasemanagedEntity] where FullName Like '%Windows.Computer%' , name sfor the server hows the "IsDeleted" column with a 0 value. So i think the db didnt notice that the computer has been deleted! After 3 days i installed the agent back with the same result. The "Is Virtual Node" property is still set to True. For now i´m trying to author a discovery to change the property.

Hello, The cluster was deleted months ago, but the name of one virtual node of that old cluster is now the name of a physical machine. I think scom "maps" the old information with the new server discovery.

if you remove the agent from the machine. You need to wait a bit at first (as you have done) but also make sure that it is not there anymore in the scom admin console in agent managed, agentless managed, pending management. If you see it than delete it. wait again. To speed up the process go to the operations manager shell and give the command: remove-disabledmonitoringobject This should go through the database and set the isdeleted column to 1 for that machine. After that grooming should do its job and remove the entry.Bob Cornelissen - BICTT (My BICTT Blog) - Microsoft Community Contributor 2011 Recipient

Hi Bob, First i deleted the server through "agent managed" view and then i uninstalled the agent from the machine! The only place i still see it is in Monitoring/"Windows Computers" View (grey). i´m going to try your tip and run the command remove-disabledmonitoringobject. Thank you.

Hello, I could not find a way to reset the value to Null, but i made a custom discovery to set the property to "False". The problem is solved! Thank you.

The command didnt work in this case because the object is not marked for deletion!

Hi, I have written a custom MP to discover all servers which have a specific reg keys. Class is a windows.localapplication and discovery for this class is targetted at windows.server.computer. When I see the results, I can only find some clustered nodes got discovered but not the nodes which are not clustered ones. Expression only inlcudes if regkey exist. I added a property to my class IsaCluster=true|false and it will pick its value from isvirtualnode property of windows.server.computer. Do you think because of this property no recieveing value for nonclustered nodes, i am able to see only clustrered seervers in my discovery view. Any suggestions how to discvoer both clustered and non clustered nodes. Let me know if I have to post the discovery XML. ThanksManish
