Re: Joe's V5R1 upgrade

I still have my doubts about how well this would work.  After all, there 
is more to an iSeries today than your production program library and your 
production data library.  Along with user profiles, authorization lists, 
IFS files, spool files, etc, etc, etc.

Basically, what would be in your system ASP?

Even if it is just OS, what about all the times that an OS upgrade goes 
out and touches every object on a system?

Mark,

    We can do this now.  You setup independant storage pools, and you can
move them from one system to another. so if you have a system ASP, and
everything else in other ASPs 1-n you can vary one off and vary it onto
another box.  It works best with SHARK I think, but was beening demoed at
the Nashville Common last year.

    So, at least in theory.  If you have two systems capable of handling 
the
workload, you could move all the user area's (storage) to system two and
them update system one with ~zero user down time.
