Database Down: Chunk Failed Sanity Check, Bad Pfget

Hello, We are running SAP using Informix on Unix. The database was fine. Then, a level '0' archive failed. The database stopped. The first message in the online log indicating failure is: I/O error, Primary Chunk 'informix/M01/sapdata/physdev3/data1 offline (sanity) chunk failed sanity check The SAP utility to start the database failed with the following error: Assert Failed: WARNING! pthdrpage:ptalloc: bad bfget Who: Session(10, informix@SAPMAR,0, -947420584) Thread(43, xchg_1.6, c785a8b0, 1)Resuts: Cannot use TBLSpace page for TBLSpace 4194305 Action: RUn 'oncheck -pt 4194305'. Then I tried bringing up the database using 'oninit' (No other options). No error was indicated on the prompt, but, once again, the online log had indicated the following problems: 'I/O error, Primary check '/informix/M01/sapdata/physdev3/data1' line(sanity). chunk failed sanity check. Then, the message '/informix/M01/sapdata/physdev6/data1' line (sanity) chunk failed sanity check The 'Asset Failed' error message previously mentioned then appeared. Any ideas or help would be greatly appreciated. Does the 'bad pfget' imply a problem with an index?
