Upgrading an Operating System: How to Prevent Discovery Problems
Best Practice: Before you upgrade the operating system on a monitored computer, uninstall the Operations Manager agent. After the upgrade, reinstall the Operations Manager agent.
Explanation: The objects that the management pack discovers, such as logical disks, are hosted by a parent class that is not version-specific. When you upgrade the operating system, the order in which discovery occurs can result in duplicate objects being discovered.
For example, you upgrade a computer running Windows Server 2003 to Windows Server 2008.
If the Windows Server 2003 discovery rules run first after the upgrade, the instance of the computer running Windows Server 2003 and its objects will be removed from discovery because the operating system base class has been removed. When the Windows Server 2008 discovery rules run, the computer and its objects will be discovered again.
If the Windows Server 2008 discovery rules run first after the upgrade, the computer running Windows Server 2008 and its objects will be discovered. When the Windows Server 2003 discovery rules run, the instance of the computer running Windows Server 2003 will be removed from discovery, but the objects hosted by that instance will not be removed.
If you upgrade a computer without uninstalling the agent first and then discover duplicate objects, uninstall the agent to mark all hosted objects as deleted in the database. Next, reinstall the agent to only discover existing applications/objects.
