Iseries Disk managment

 I'm a fossil and have been around since 360/20 days. Other than using
RGZPFM to re-organize some very volatile file on my career long boxes, I
just realized that I've not thought about or worried about defragging
the drives as a whole.

I revitalized some of my grandkids laptops this last weekend by simply
defragging them.  

The question of why we don't need to do that on the Iseries boxes popped
into my head. 

Is that because the don't need to have it done, or we really do need to
do that and is it like the early days when IBM just didn't give us the
same tools and features that existed on other boxes. That's not
necessarily a complaint because I think many may have stayed out of
trouble by not having some more esoteric features available.

There is also the issue that they write books about what I don't know
about that which I work on. [grin]
