GFS (Global File System) does this with the help of special drive firmware. They are trying to push dlocks (device locks) into the scsi standard so multi-initiator setups would be possible without performance degradation that would be unavoidable if the storage media is used for implementing locking.
There are also some commercial offerings that have this kind of functionality.
