Given the config you've described, I think only Oracle or VxVM could be to blame for that. Since the DMX is virtualized by VxVM and the problem happened on 60-70 datafiles, I think the odds are too astronomical that the DMX did it since those magic last blocks are strewn all about. -- //www.freelists.org/webpage/oracle-l
