How to store logical logs to disk

All, Product/Server: Informix Dynamic Server 7.30.UC2 on HP-UX 10.20 Problem: I am attempting to store logical logs to disk to allow them to be backed up with the Unix filesystem each night. I have 2 hard disks each known as Volume Group "vg00". The / filesystem on one disk and the /users filesystem on the second disk. Informix is loaded on the /users filesystem and there is a third disk which is the raw device for dbspaces. I have added another logical volume "lvlogs" to /dev/vg00 which consumes about 232 MB of space which was free. I then mounted /dev/vg00/lvlogs onto a new filesystem called /logs. Changed the onconfig file to point to /logs/logical, where 'logical' is a file I created with zero bytes, and started the informix engine. Everything come online but I attempted to backup the logical logs to this new file and I get the error "cannot write log". I have attempted numerous links (ln -s /logs/logical /dev/tapedev), checked permissions, etc...but nothing seems to work. The manuals do not cover this sort of detail and have had no luck with some of the informix sites on the web. Can someone please help. TIA Cheers, Greg. --------------------------------- Greg McGregor CAG SysAdmin/DBA NDS Asia Pacific P/L gmcgrego@vitgcdu1.telstra.com.au 0418-645-426 (1st) (+613) 9256-5967 (2nd) ---------------------------------
