Interesting Problem! 2 VIOs, One is problematic, assigning disks and resources from the other only
Hi,
The scenario is like this:
1.We needed to assign two hdisks to an LPAR
2.SAN team gives us two ldevs
3.One of our VIO is hanging on cfgmgr operation
4. We ran cfgmgr on the smooth VIO. Got the disks and assigned the disks from there to the LPAR.(By passed the other VIO as in didnt run cfgmgr on them this time)
5. On the LPAR ran cfgmgr but the LPAR would also hang this time.
My question is that is this the right way? Because one of our engineers was feeling that we need to have the disks on the second VIO as well and then proceed on the LPAR because the LPAR sees resources from both VIO. something like that. Is there a work around?
The VIO that hangs on cfgmgr has errpt showing a failed disk operation on some old disk. Can that be the problem for the VIO hanging on and on?
Regards

roar_vs_connection_obj(3) RoarAudio Programmer's Manual roar_vs_connection_obj(3) NAME
roar_vs_connection_obj, roar_vs_stream_obj, roar_vs_vio_obj - VS API interface for use of main API SYNOPSIS
#include <roaraudio.h> struct roar_connection * roar_vs_connection_obj(roar_vs_t * vss, int * error); struct roar_stream * roar_vs_stream_obj (roar_vs_t * vss, int * error); struct roar_vio_calls * roar_vs_vio_obj (roar_vs_t * vss, int * error); DESCRIPTION
Those functions return internal connection, stream and VIO object of the VS object. They are used to use the main API with a VS opened stream. roar_vs_connection_obj() returns the connection object used for the control connection to the server. roar_vs_stream_obj() returns the stream object storing information about the stream. roar_vs_vio_obj() returns the VIO object used to read data from or send data to the server. Returned objects are freed as soon as the VS object is closed. If the VS object was created using roar_vs_new_from_con(3) the connection is not closed by the VS object and stay valid after close until it is closed by the program or library. The VIO object MUST NOT be used while in buffered mode. PARAMETERS
vss The VS object to return internal objects from. 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 these calls return the described object. On error, NULL is returned. EXAMPLES
