Markus, Good catch!
I did hear, though, that due to the file system design, perhaps pre-formatting volumes on AIX will cause fragmentation rather than preventing it. I'm not an AIX guy but would hope that someone who is would weigh in here. Thanks, Kelly J.

Hi all, just my two cents on file-deviceclass: I agree with Kelly that Volumes should be predfined to avoid fragmentation. In addition I would very strongly recommend running the define volume command with a wait=yes to format them sequentially. While this looks a pain, volumes will be formatted without fragmentation one would get formatting several volumes at a time. Pre-formatting volumes may take it´s time (to be percise, formatting on Sun Solaris can be very slow, while W2K3 is rather quick due to differences in the filsystem!), but you just run it once and it can be run in the background.
