You need to first create the file that you will reference as the chunk. In Unix, use the touch command to create the file in the appropriate directory - next chmod the file with the appropriate read/write/execute. Last change the owner and group to be informix.
first of all excuse me for my english....i hope you understand what i'm asking...
i already have permissions for this file. this file was used for another chunk, that i deleted. there was a chunk llinked with that file, i delete the chunk, and i want to create a new chunk in other dbspace, and i want this new chunk to be linked with the old file. the previously file is still here with the same permisions as before. i just want to relocate a chunk in another dbspace. so what's the problem?
I don't know how it worked with 600 permission; You will need 660 with informix informix own/grp.
Only informix wil access this raw device so why wouldn't it be a good idea.
You'll see, once you changed it, it will work!
Are these raw devices used by Informix?
If so, you could end up with some big problems where you 'd have to restore the database....
I would strongly suggest you to change the owner and group to informix for all raw devices used by Informix.
