VIO is an LPAR
When the LPAR build is started a choice is presented to either build an LPAR or a VIO server. The VIO server presents virtual devices to other LPARs contained in the same Power series frame. The virtual devices presented are virtual Shared Ethernet Adapters (SEA); virtual SCSI adapters; and virtual Fibre adapters (NPIV). In a single Power system it would be bad practice to have only 1 VIO server. The VIO setup is all about resilience with each VIO server supplying failover capability to client LPARS.
The VIO server uses a subset of AIX and the VIO user (padmin) runs in a restricted shell and has a different command set. The VIO server should not be considered as another LPAR, it is a VIO server!
Building a VIO server can be done either by the Graphical User Interface on the Hardware Management Console (HMC) or running a script in an SSH session on the same HMC.
I hope this helps somewhat.

yum-list-data
yum-list-data(1) yum-list-data(1)
NAME
yum list data plugin
SYNOPSIS
yum [options] [command] [package ...]
DESCRIPTION
This plugin extends yum for some commands that give aggregate package data based on lists of packages
added yum commands are:
* list-vendors
* info-vendors
* list-rpm-groups
* info-rpm-groups
* list-packagers
* info-packagers
* list-licenses
* info-licenses
* list-arches
* info-arches
* list-committers
* info-committers
* list-buildhosts
* info-buildhosts
* list-baseurls
* info-baseurls
* list-package-sizes
* info-package-sizes
* list-archive-sizes
* info-archive-sizes
* list-installed-sizes
* info-installed-sizes
* list-groups
* info-groups
all of which take the same arguments as the list and info yum commands. The difference between the list and info varieties is that the info
versions lists all the packages under each aggregation.
list-vendors, info-vendors
Is used to list the aggregate of the vendor attribute on the packages, examples are "Fedora Project" and "Red Hat, Inc.".
list-rpm-groups, info-rpm-groups
Is used to list the aggregate of the group attribute on the packages, examples are "Applications/System", "Development/Tools" and
"System Environment/Base"
list-packagers, info-packagers
Is used to list the aggregate of the packager attribute on the packages, examples are "Fedora Project" and "Red Hat, Inc.".
list-licenses, info-licenses
Is used to list the aggregate of the license attribute on the packages, examples are "GPL" and "MIT"
list-arches, info-arches
Is used to list the aggregate of the arch attribute on the packages, examples are "i386" and "x86_64"
list-committers, info-committers
Is used to list the aggregate of the committer attribute on the packages, this is taken from the most recent changelog entry of the
package.
list-buildhosts, info-buildhosts
Is used to list the aggregate of the buildhost attribute on the packages, examples are "mybuilder.example.com" and "xen-
builder1.fedora.redhat.com"
list-baseurls, info-baseurls
Is used to list the aggregate of the url attribute on the packages after discarding the path of the URL, examples are
"http://yum.baseurl.org/" and "http://www.and.org/"
list-package-sizes, info-package-sizes
Is used to list the aggregate of specified ranges the packagesize attribute on the packages, examples are "[ 1B - 10KB ]" and "[
750KB - 1MB ]".
list-archive-sizes, info-archive-sizes
Is used to list the aggregate of specified ranges the archivesize attribute on the packages, examples are "[ 1B - 10KB ]" and "[
750KB - 1MB ]".
list-installed-sizes, info-installed-sizes
Is used to list the aggregate of specified ranges the installedsize attribute on the packages, examples are "[ 1B - 10KB ]" and
"[ 750KB - 1MB ]".
list-groups, info-groups
Is used to list the aggregate of the yum groups that the packages are in, examples are in "yum grouplist". Note that in yum groups a
package can be in more than one group at a time.
It is worth noting that some of the above data can be "unknown", to yum, at which point a separate aggregation called "-- Unknown --" is
listed.
EXAMPLES
To list all the groups that have an update, along with the number of packages in each group, use:
yum list-rpm-groups updates
To list all the committers to packages that have yum in their name, use:
yum list-committers 'yum*'
To list ranges of the sizes of packages installed or available, use:
yum list-package-sizes
To list yum groups that have an update, use:
yum list-groups
