That is exactly what I'd like to do. The nodes cannot boot from a diskette 
however but I do have network boot available to me.

So, concatenate all of the drive space and form multiple roots? Then just add 
storage space to the overall storage on the fiber channel side? I've been 
doing it the other way around, I've been creating multiple allocations of the 
centralized storage so that I would have a web root, a mail root, etc.

U certainly will, thank you very much for the input Mark.
