INFORMIX ONLINE 4.10.UE2 vs 1.4Gb HITACHI DRIVE

INFORMIX ONLINE 4.10.UE2 vs 1.4Gb HITACHI DRIVE One of our clients is running an EISA 486 with a SCSI bus, SCO Unix 3.2 as the operating system and Informix Online version 4.10.UE2. The original system was successfully running with the chunks allocated to raw disk on a ????? 660 Mb disk. We recently had a Hitachi 1.4 Gb disk added and had allocated the raw disk to 4 informix chunks (2 x 50 Mb, 1, 800 Mb, 1 x 500 Mb). Not long after begining normal operations we started getting ISAM errors (cannot find system catalogs) and turbo.log has "bad page" errors. eg: 07:58:50 bfcheck: bad page: pg_addr 323af8 != bp->bf_pagenum 205578, userp = 80401d74, pid = 4408, uid = 227 07:58:50 buffer header: 07:58:50 804d78c4: 00000000 00000000 74204d80 74204d80 ........ t M.t M. 07:58:50 804d78d4: f4034080 c0c74d80 02000000 2d0c0000 ..@...M. ....-... 07:58:50 804d78e4: 78552000 00485480 00000000 00000000 xU ..HT. ........ 07:58:50 804d78f4: 01000000 5cda4d80 00010000 ....\\.M. .... 07:58:50 page header: 07:58:50 80544800: f83a3200 37e45900 3c000100 e9062300 .:2.7.Y. <.....#. 07:58:50 80544810: 00000000 00000000 ........ 07:58:50 slot table and stamp: 07:58:50 80544ffc: 37e45900 7.Y. 07:58:50 -- Fail Consistency Check -- btsearch:bad btree node -- pid=4408 user=227 us=80401d74 We tried replacing the disk drive as we thought this may be the problem but the same errors re-occurred. After contacting Informix support in Australia we tried using cooked unix files instead of raw disk as they suggested. This time we could not even import our database (using dbimport) before similar errors occurred. Is there anybody out there who has come across a similar problem or who may have some suggestions. This is unfortunately supposed to be a solution to another problem - and is causing much grief due to the fact it is the clients production system. Any help is appreciated ASAP!!!
