Which type of LUN is that one?
Is this a dynamic disk?
Looks like a kind of comunication issue between the windows machine and the virtual environemtn (i guess this is an RDM lun). Did you already try to restart the SD service?

Rebooting the Windows-Server solved the problem.
From SnapDrive created LUN's should be never changed with other tools like OnCommand System Manager or windows disk management.
These LUN's have have a special disk geometry from SnapDrive.
Example: Resizing a Snapdrive-LUN with OnCommand System Manager create huge "busy" snapshots in a Snapmirror-Relationship, that cannot be deleted!
