Applies To: Windows Server 2008 R2
Volume Shadow Copy Service (VSS) providers manage running volumes and create shadow copies of them on demand.
|Product:||Windows Operating System|
|Message:||The LUN resynchronization operation failed because the destination disk could not be found or because another application holds an exclusive handle to the destination LUN.
Make sure that all applications have released their handles to the LUN and retry the operation.
Ensure that the destination disk is online and no application has an open handle to it
This event indicates that the destination disk could not be found or that another application holds an exclusive handle to a destination LUN.
Possible resolutions include:
- Ensure that the destination disk exists and is online.
- Close any application that might have an open handle to the disk drive indicated by the event. If necessary, contact the application vendor about this problem. You can use a utility called Process Explorer to view handles to the root directory on the disk. For information and download instructions for Process Explorer, see http://go.microsoft.com/fwlink/?LinkId=157123. If the destination disk is online, no application has an open handle to it, and the issue is still not resolved, restart the computer.
To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.
Ensure that the destination disk exists and is online

- Type select disk <n>, where <n> is the destination disk, and then press Enter.
