Re: LPARS (was NT vs. AS/400)

I looked at your note  a second time  and thought  you
might mean software release support.
At V4R4 it is V4R4 only Then comes  the +1 or -1 rule at
V4R5/V5R1.  
There are  several tables which show the matrix which is  both
hardware model and software release dependent. You need the tables 
to be accurate beyond the general rule of +/- 1.  

There is a one time case of difference of 2 releases.

Just re-read the article. It says in there:
"Previous releases are not supported in a logical partition".
Now that is strange. If the LPAR can run Linux why not V4R1?
or V3R7? for that matter.

What would be the technical reason for this restriction?
Lifting it would be great for all those shops that stay on
older releases for whatever reasons. Also great for
software developers for testing and ensuring backwards
compatibility.
