something else

when my Suse 10 SP3 loads when HBA attached I see my LUNs twice

for instance I created LUN1 60GB and I see it twice...? are those 2 related I think the slow load process and the diuplicated LUNs

muroar_stream(3)					    muRoar Programmer's Manual						  muroar_stream(3)

NAME
muroar_stream - Create a stream connected to a RoarAudio sound server SYNOPSIS
#include <muroar.h> muroar_t muroar_stream (muroar_t fh, int dir, int * stream, int codec, int rate, int channels, int bits); DESCRIPTION
This function connects a stream to a sound server supporting the RoarAudio protocol. It takes a connected control connection created with roar_connect(3) and converts it into a connected stream. The socket can no longer be used as control connection. PARAMETERS
fh The connected control connection. dir The stream direction for the new stream. For playback of a waveform stream (PCM data) this is MUROAR_PLAY_WAVE. For all possible values see the offical muRoar manual. stream This is a pointer to an integer muRoar stores the stream ID in. If your application does not need to know the stream ID of the new stream this can be set to NULL. codec This is the codec to be used for the new stream. For signed PCM in host byte order use MUROAR_CODEC_PCM or MUROAR_CODEC_PCM_S. For unsigned PCM use MUROAR_CODEC_PCM_U. There are a lot other codecs defined. However using a codec not supported by the server will result an failure of this call. For all possible values see the offical muRoar manual. rate This is the sample/frame rate the new stream will use. For streams this setting does not make any sense set this to zero. channels This is the number of channels for the new stream. For streams this setting does not make any sense set this to zero. bits This is the number of bits per sample to be used by the data. For streams this setting does not make any sense set this to zero. RETURN VALUE
On success this call return the new stream IO handle. This may be the same as the control connection or a new one and the control connec- tion is closed. On error, MUROAR_HANDLE_INVALID is returned. BUGS
In failure where is no way to tell was was going wrong. HISTORY
This function first appeared in muRoar version 0.1beta0. SEE ALSO
muroar_connect(3), muroar_close(3), RoarAudio(7). muRoar April 2012 muroar_stream(3)
