Urgent help required adding dbspace on new IDS 7.24 installation

I am installing IDS 7.24 on HP-UX 10.20. I have a 2GB drive which has 1332MB allocated as raw device rlvol2. I have created chunk /dev/vg01/online_7.24 which is linked to rlvol2. My configuration file has 150,000KB for rootdbs. I have intialised disk space and OnLine was started ok. When I attempt to add another dbspace, offset 150,000KB, size 1150,000KB with full pathname set to /dev/vg01/online_7.24, I get the message "the chunk specified already exists". (Mirror and Temp set to N). I have already performed identical installation on my development machine but for some reason it doesn't work on my Production machine. All help appreciated. I need to get my application up and runnig this weekend Regards Diane Houston OASIS Application Support MedAS R135 at Villiers House extension 19575 The Information in this communication is confidential and may be privileged and should be treated by the recipient accordingly.
