RE: i5 vs. p5

Sure it can, if you have dedicated p5 I/O hardware attached to the i5.
Likewise, if the CEC of the p5 supports i5/OS, you should be able to do
i5/OS against a pSeries as long as you have the hardware needed for I/O.

An HMC would be required, naturally.  Dedicated I/O would be required.
According to the prophecy, it should indeed work - the OS in each
partition when using dedicated hardware has nothing to do with the
others.  You'd get a failure in LVT making this system (because you
can't make a 9406 and not have at least one i5/OS LPAR), but in the
field you'd be able to get an i5 570, have the CEC defined as i5/OS with
6 drives, add requisite p5 hardware outside on the RIO loop, and never
install i5/OS (heck, remove the drives) - it would work.  I can't see
why it wouldn't.

This is the kind of experience that I was looking for.  Now what about a
box with an HMC?  A couple of years ago I was at an HMC session at the
Design Center in Austin.  (Steve L. was there also; help me remember,
Steve.)  I thought that I remembered the presenter saying at that time
that you would be able buy an iSeries or a pSeries and not even load the
O/S, you could just create all of the partitions from the HMC and load
them up with Linux, for example.

It was very obvious at that session that the pSeries people (even though
some had already worked with HMCs) did not have nearly as many O/S
features as we did.  They'd never even heard of virtual ethernet or
virtual optical at that time.

Shortly after Linux became supported on the iSeries I asked an IBM
presenter why AIX was not yet supported.  (How could AIX be harder to
port than Linux?)  I was told that it was working in the lab but had not
yet been GA'd because of "politics."

So I'll try to be even more specific.  Can AIX be loaded on an i5 with
an HMC and no i5/OS partition?  Or vice-versa.  If it costs "a GAZILLION
dollars" to run i5/OS on a p5 what else do you need to buy?  Or do you
just need a GAZILLION dollar p5?

You cannot load i5/OS on "any" p5.

I tried loading v5r5 on a p5 520 specificially:
Machine type-model: 9111-520

I brought in parts to support it but I could not get it to "D" IPL to
CD.

After talking to some IBM'ers there appears to be some kind of  feature
code stuck in the FSP that will not allow i5/OS to be loaded.
