It's very simple. raw is not an option.

raid10 or raid50 is probably best. JFS2 is always better than JFS.

since db2 creates all the db and log volumes, you don't need to worry about 
that either.

db2 logs on a LUN optimized for sequential I/O, the db of course on LUNs 
optimized for random I/O.
