Unix VIO vs Dynamic LPAR

Can you have a Dynamic LPAR without VIO and if yes is there a benefit to having both? I am attempting to implement VIO and Resource pooling at my company and want to understand the limitations.

Also, I have been told the managing and allocation of the Logical Volumes is a time consuming task as they have to be managed at the SAN level as well as the VIO partion, is this correct as well?

Thank you in advance

roar_vs_file(3) 					   RoarAudio Programmer's Manual					   roar_vs_file(3)

roar_vs_file, roar_vs_file_simple, roar_vs_new_from_file - File mode for VS API SYNOPSIS
#include <roaraudio.h> int roar_vs_file(roar_vs_t * vss, struct roar_vio_calls * vio, int closefile, int * error); int roar_vs_file_simple(roar_vs_t * vss, char * filename, int * error); roar_vs_t * roar_vs_new_from_file(const char * server, const char * name, char * filename, int * error); DESCRIPTION
These functions are used to open the VS object in file mode. In the file mode the VS API reads or writes the data from or to the file itself. The file mode uses normal VIO/DSTR so it supports streams as well. Just pass the stream URL as filename. roar_vs_file() sets up the file mode for a already opened object using the open VIO handle vio. This function requires the use of roar_vs_stream(3). roar_vs_file_simple() sets up the file mode using a given filename (or URL). It opens the file using DSTR API. By default the function assumes playback mode and tries to auto detect the audio parameters. To override the auto detection or use a diffrent stream direction use roar_vs_stream(3). roar_vs_new_from_file() creates a new VS object and enters file mode using the file (or URL) given as filename. To send data to or read data from use roar_vs_iterate(3) or roar_vs_run(3). PARAMETERS
server The server to connect to. NULL for defaults. name The application name. This should be something the user can use to identify the application. It MUST NOT be the application's binary name or the value of argv[0]. vio The VIO handle to be used by the file mode. closefile This parameter tells the file mode if the file should be closed on roar_vio_close(3). Must be ROAR_VS_TRUE (common) or ROAR_VS_FALSE. filename The filename used to open the file for file mode. The file is opend using DSTR API. All kinds of files supported by DSTR are sup- ported. This includes HTTP streams. error This is a pointer to a integer used to store the error value in case of error. This can be NULL if not used but it is very recom- mended to use this error value to report good error messages to the user. RETURN VALUE
On success roar_vs_new_from_file() return a new VS object. On error, NULL is returned. roar_vs_file() and roar_vs_file_simple() returns 0 on success and -1 on error. EXAMPLES
roar_vs_t * vss; int err; vss = roar_vs_new_from_file(NULL, "MyApp", "http://...", &err); if ( vss == NULL ) { //handle error. } if ( roar_vs_run(vss, &err) == -1 ) { //handle error. } if ( roar_vs_close(vss, ROAR_VS_FALSE, &err) == -1 ) { //handle error. } SEE ALSO
