Shared processor, but I am not concerned with processor min/max at this point.
I want to power off a partition that currently has some resource assigned to it. My feelings are that once powered off, that resource should be up for grabs if I so desire. Unfortunately it appears that the first time you power on a partition with XYZ resource assignment, then those resources aren't available again until you DLPAR, or change profile to absolute minimums then reactivate, or remove the profile completely.
The idea is to make all those resources available to other partitions without removing the profile. I am aware I can DLPAR everything but the absolute minimum, or change the profile and reactivate with absolute minimums.
Hope this makes sense....even though it may not be possible. I am chasing intuition here.....

Ok, I may be on the wrong track here, but,
Processors:
Are you using Dedicated or Shared?
What are your settings for Minimum, Desired, and Maximum?
Let's say you have three processors. Let's say lpar A has 1 and B has 2 for all three fields. I don't believe you can add the 1 from A to B since B is already at the maximum without powering down B, changing it's configuration to perhaps Min=0.1, Desired=2, Max=3 (or more) and activating it from this modified configuration.
Kind of the same process for Memory.
Dynamic lparing is great. I use it frequently to move memory and processors around. However, you have to have your minimums and maximums configured correctly. Keep in mind, CUD or Capacity Upgrade on Demand (why am I suddenly in the mood for a drink?). You may have more processors, that you can activate live by entering a code. However, if your maximums were built on the old limits you may have just shot yourself in the foot and disabled your ability to do this non disruptive. I've done a few CUDs (both kinds).

I don't believe you have to remove the profile. This isn't where you need
to change the settings with the lpar live, then power it down so as to
de-allocate them??

All,
Perhaps I am having a lapse in memory, but I thought that once a
partition
is powered off all its processor/memory resources could be brought back
to
the available pool without having to remove the powered-off partition
profile. Is there a way to return this resource to the available pool
without 1) deleting the profile, 2) reactivating with new profile
config,
3) using DLPAR to strip it down to "bare bones" before the partition is
shut off?
