Question: Shared Mem Init problem

Hello, it would make my week if someone could tell me what is going on and how to fix it. I have 6.0 running on a Sparcstation2. When booting, I get the following error messages on the console: oninit: cannot open chunk '/dev/rsd16h' see online message log oninit: fatal error in shared memory initialization The online message log goes like this: Mon Nov 28 09:41:27 1994 09:41:27 warning: chunk timestamps are invalid 09:41:28 I/O error, Primary Chunk '/dev/rsd16h' -- Offline (sanity) 09:41:28 INFORMIX-OnLine Stopped 09:41:29 mt_shm_remove: WARNING: may not have removed all/correct segments I have looked into using SunSolve to find the answer, but the amount of info about chunks and shared memory and timestamps is enormous. I could see looking through it for days and not finding a solution. Has anyone run into this before? Am I missing something obvious? Thanks in advance for your suggestions/solutions! -- Alan BTW. I have seen the thread about putting an offline chunk back online with hex editor, but tbcheck -pr does not work when shared memory init failed. -- solsbury@cais.com*Splunge*Alan Salisbury*Sys Admin/PA/MusicLover*Unix/Informix/ Aerosmith/Beatles/Boston/Clapton/Eagles/ELO/Enya/Fleetwood Mac/Peter Gabriel Heart/Jethro Tull/Elton John/Billy Joel/Journey/Led Zeppelin/Moody Blues Van Morrison/Tom Petty/Pink Floyd/Queen/Steely Dan/Stevie Ray Vaugn/ZZ Top
