As to the last part, creating and removing partitions more often that maybe
several times a year, then you really need to consider PowerVC, which has
most if not all that capability.

Hello Jim,

thanks for your extensive answer.

The short answer is yes, every partition needs it's own disk adapter and
disk units.

Adapter: Also in the hosting LPAR? I know from the linked document that
"Disk Units" (aka: Files in IFS) will be given to the LPAR via *NWSD and the
OPT01 of the hosting partition will magically appear there, too. :-)

The next steps are outlined in the linked document in my original mail. But
I appreciate you taking time for me.

Note: 35*1024=35480, but you have to leave room for virtualization
and a few other things that take about 12%, so I always use # Gig I want *
1024 *
1.12 = nwssize. Others may argue with the formula, but it works.

I'm creating at least 40 GiB to have a bit of space for actual content. But
it's good to know that I'm not too far off with my guessing.

Clearly I did not show you all the steps.

Don't worry, they're laid out rather easily in the linked document.

I'm working on an open source version of a program that would create the
virtual devices on the HMC, build the partition, do the above, then start
the partition.

Cool! I think this is very handy if there's a lot of creation and deletion
of partitions happening.

:wq! PoC
