Re: LPAR Planning

Chuck:

I do a fair amount of LPAR planning and I would suggest the following:

1. GOTO the LPAR website and read everything you can. Familiarize yourself
with the process of planning, how to use the worksheets and when to send
them to Rochester for validation.
http://www-1.ibm.com/servers/eserver/iseries/lpar/

2. Download the LPAR Validation Tool from this site. This tool is extremely
valuable in designing LPAR machines. There is a User Guide out there also
so you can learn how to use the tool. If you are doing a purely 8xx
solution you can design the whole machine with the LVT. IF you are doing a
combination of 7xx and 8xx hardware, i.e. mig towers. You will also need to
download the worksheets which are used to help plan the machine.

3. Always remember that the most critical part of LPAR (IMHO) is Planning.
When in doubt, read this again.

4. If it is feasible for you, I would highly suggest going to Rochester for
the LPAR class. It is excellent and allows you to get some hands on before
you start working with LPAR. They spend a fair amount of time on (surprise)
planning and system design as well as implementation.

5. Realize that when you go to actually placing the machine into eConfig,
you must specify the #0140 feature on the config, which indicates that it
will be an LPAR box. This feature triggers a restricted build in Rochester
which essentially does not allow a preload of the OS or SLIC. It also means
that when you get the machine, the cards will generally not be in the slots
you need them in.

Therefore, you will need to be sure you KEEP A COPY OF YOUR LVT OUTPUT AND
WORKSHEETS!!!!  as these docs are actually what you or the CE will use to
configure the hardware on the machine - both physically and logically.

I have a client that is wanting to look at LPAR.  (Replace two AS/400's
with
a single, larger system.)  We are just starting to examine this.  Neither
I,
nor anyone else here, has set up a LPAR system before.  I have found the
"Slicing the AS/400 with Logical Partitioning: A How to Guide" and
"Capacity
Planning for Logical Partitioning on the IBM  iSeries Server" redbooks.
Does anyone have any other suggestions for sources on preparing for using
LPAR's?

TIA,
