If onspaces will not mark the chunk up then the data on it has been damaged. If you have a recent archive restore that dbspace from archive including rolling any logs forward. If you have no recent archive you are hosed. You can try to have Informix Tech Support force mark the chunk online but then it may or may not be usable and I'd recommend unloading EVERYTHING in that dbspace drop the tables, drop all the chunks, recreate the dbspace and tables, and reload. You say you have hardware mirror. Are there mirror errors in the system log or the array's log? If so try dropping the damaged side of the mirror and rebuilding it (perhaps after replacing the drive), assuming of course you did not do that already. No insult, if I don't mention the 'dumb' stuff you may get to beat your head for no reason. Art S. Kagel George Ayou wrote: > > This message is in MIME format.
