Operating Systems AIX What's the difference between VIOS and LPAR? Post 302522905 by johnf on Tuesday 17th of May 2011 03:46:54 AM

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.

NAME
libroar - RoarAudio sound library roarvs - RoarAudio very simple API SYNOPSIS
#include <roaraudio.h> roar_vs_t * vss; DESCRIPTION
The VS (for Very Simple) API is a high level abstraction layer used to allow use of RoarAudio from very simple programs. The API was designed to help people to easly upgrade existing artsc and pulse-simple code to RoarAudio. While the API is equivalently simple it is much more powerful than one one by aRtsc or PulseAudio. The VS API also has a mode to play back (and record) files easly. As this uses VIO/DSTR it can handle streams as well. TUTORIALS
Tutorials can be found in roartut(7). IMPORTANT FUNCTIONS
There are several important functions. This is a small list of the most important ones. Error handling roar_vs_strerr(3) Opening roar_vs_new(3), roar_vs_new_simple(3), roar_vs_new_playback(3), roar_vs_new_from_file(3) Closing roar_vs_close(3) Reading and writing roar_vs_read(3), roar_vs_write(3) Non-Blocking and Asyncron IO roar_vs_blocking(3), roar_vio_select(3) Volume and Flags roar_vs_pause(3), roar_vs_mute(3), roar_vs_volume_mono(3), roar_vs_volume_stereo(3), roar_vs_volume_get(3) Meta data roar_vs_meta(3), roar_vs_role(3) File mode roar_vs_file(3), roar_vs_file_simple(3), roar_vs_iterate(3), roar_vs_run(3) Buffered mode roar_vs_buffer(3), roar_vs_iterate(3), roar_vs_run(3) BUGS
