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.
