RE: System Planning Tool (CPU %)

["Haase, Justin C." <justin.haase@xxxxxxxxxxxx>]

You can change processor, both assigned power and virtual quantity with
dynamic LPAR.  If you want it to be permanent, you then need to change
the partition profile and stop the LPAR and restart from the changed
profile.  However, you can do temporary changes (until next profile
start) via dynamic LPAR with no system availability being affected.
Keep in mind that removing large amounts of RAM from one LPAR can take a
while.  Adding processor and memory from the available pool is
relatively fast.

1 - When discussing the SPT with my CE it's been our experience that
BP's 
work diligently on making sure that your cards, etc are exact.  Though,
as 
far as allocating memory and processor to each lpar they pretty much
take 
a WAG and the customer is expected to adjust that.  The local CE has
used 
the SPT to install a 3 lpar system and a 10 lpar system and it worked
like 
a charm.  So well in fact that he'd like to find customers not using it
on 
occasion just to keep how to do it manually fresh in his memory.

2 - Your other question.  How tricky is it to change memory or
processor? 
I do not think an IPL is required.  Keep in mind, that you can configure

minimum and maximums allowed to each lpar, and then how much to
currently 
use.  I think that changing the current allowed is no big deal, as long
as 
it fits in that range.  I don't remember exactly, but changing the range

may involve a disruption of service.
