thanks for the help guys.
it's not insulting to say I lack the understanding of PowerVM, it's OK! I know I don't understand it that's why I'm here..
ok so in a nutshell,here's what I have:
we purchased a server 8202-34b with two enclosures, g30 and d24. we don't have the amperage to hook up the enclosures, they need 220v lines and a PDU ,so I'm only running off of the 8202 until the new electric is installed.the 8202 has 6x146GB disks installed,128GB RAM, 6 cpu. plenty enough to get started with.
so, the system came pre-loaded with one partition, AIX 7.1. we wanted 6.1.so, via ASMI, I reset to factory config which makes one partition that takes up all resources, and its name was that of the serial number of the server.. I just deleted all partitions, so I have nothing but the server listed under system mgmt-> servers)
I want to make 2 virtual machines,each AIX 6.1, 32 GB RAM, one with 1 CPU max ( sybase server licensing is very costly beyond one CPU) , and the other with 2 CPU max and 32GB RAM.
so to start with, am I correct in assuming I need to have at least 1 virtual I/O server installed , before I create these two AIX 6.1 partitions? if the answer is yes, that's where the problem lies.as you guys know,vios stops at the '37% finished' mark,and asks "insert disk #2 and hit enter"
I do that, disk #2 fails to load, kicks me to a root # prompt.exit that,and you're at init mode. I've reburned the dvd 3 times, thinking it was bad media.I've downloaded the disk 3 times from IBM thinking it was a bad ISO from IBM.
this is where I'm stuck..I cannot install vios either manually as stated above, or as a template because the template install stops at the prompt> "enter location of source disk 2", but since it is a read-only terminal, I cannot input the location, even though it is in the exact same location on HMC repository as vios disk #1,and despite IBM's docs saying it will automatically pick up disk 2 from same location as disk 1.
I now have 0 partitions since I deleted everything.I'm going to start over, try to install vios server first, then a second vios server if possible.
my apologies if I've confused you..
NIM server is not something I'm interested in, it means reading more documentation and configuring another AIX server to use it as the NIM master. it simply can't be this hard to install VIOS..and it shouldn't be..
why doesn't IBM offer an OVF format VIOS appliance and/or as single VIOS
DVD.I have read a lot of people saying that they're stuck exactly where I am, at disk #2, it fails,and they can't get past it.

HTH
the doc link you included in your post, isn't available on redbooks.ibm.com.
to answer your question, yes all of what you said makes sense.I just can't set up
a vios server to begin with!
that's where the problem is.

CCD(4) BSD Kernel Interfaces Manual CCD(4)
NAME
ccd -- Concatenated disk driver
SYNOPSIS
pseudo-device ccd [count]
DESCRIPTION
The ccd driver provides the capability of combining one or more disks/partitions into one virtual disk.
This document assumes that you're familiar with how to generate kernels, how to properly configure disks and pseudo-devices in a kernel con-
figuration file, and how to partition disks.
Note that the 'raw' partitions of the disks must not be combined. Each component partition should be offset at least one cylinder from the
beginning of the component disk. This avoids potential conflicts between the component disk's disklabel and the ccd's disklabel. The kernel
will only allow component partitions of type FS_CCD. But for now, it allows partition of all types since some port lacks support of an on-
disk BSD disklabel. The partition of FS_UNUSED may be rejected because device driver of component disk will refuse it.
In order to compile in support for the ccd, you must add a line similar to the following to your kernel configuration file:
pseudo-device ccd 4 # concatenated disk devices
The count argument is how many ccds memory is allocated for at boot time. In this example, no more than 4 ccds may be configured.
A ccd may be either serially concatenated or interleaved. To serially concatenate the partitions, specify the interleave factor of 0.
If a ccd is interleaved correctly, a ``striping'' effect is achieved, which can increase performance. Since the interleave factor is
expressed in units of DEV_BSIZE, one must account for sector sizes other than DEV_BSIZE in order to calculate the correct interleave. The
kernel will not allow an interleave factor less than the size of the largest component sector divided by DEV_BSIZE.
Note that best performance is achieved if all component disks have the same geometry and size. Optimum striping cannot occur with different
disk types.
Also note that the total size of concatenated disk may vary depending on the interleave factor even if the exact same components are concate-
nated. And an old on-disk disklabel may be read after interleave factor change. As a result, the disklabel may contain wrong partition
geometry and will cause an error when doing I/O near the end of concatenated disk.
There is a run-time utility that is used for configuring ccds. See ccdconfig(8) for more information.
WARNINGS
If just one (or more) of the disks in a non-mirrored ccd fails, the entire file system will be lost.
FILES
/dev/{,r}ccd* ccd device special files.
