I have same lun (hdisk3) assigned to 2 vios server (dual vio server) and this is mapped to the client lpar. I have sddpcm on the VIO.
On the VIOA, the attributes for fscsi1 and fscsi3 are set to fast_fail and dyntrk is set to yes
Now, if I do a lqueryvg -Atp on the hdisk3, I get a "DISK OPERATION ERROR" and a related fscsi1.
I am trying to understand , if this is due to scsi reserve issue or is it a zoning issue. With sddpcm, the hdisk reserve_policy is set to no_reserve by default.
I still have to find out if any errors are reported on the switch.
Can anyone recommend me some reading material surrounding how AIX handles LUNs:
- with and without MPIO installed
- with and without SDD or SDDPCM installed
Where does lspath sit in all of this (MPIO layer?). Can a system be built with just MPIO software? Is MPIO software even needed?
I guess... (0 Replies)

Hi folks.
We want to move a "physical" AIX box to a VIOed LPAR. The physical box is running SDD with disks from a DS8300. I want to be able to reattach those LUNs from the DS8300 to my VIO server which is running SDDPCM and then assigned them back to my AIX LPAR. Any thoughts about this?

Hi Guys,
I'm working on building a new 595 machine.. I'm try to achieve high availability for the VIO clients using 2 VIO servers, The ethernet part is satisfied using SEA failover, Now how do I achieve redundancy for the disks, its the servers internal disk attached to the scsi cards...

We have AIX 6.1 system attached to SAN disks (DS4700 and DS8100) thru SVC.

I am planning carving out dual VIO servers on a P750 based and would like to know how to allocate internal disks to the VIOS. This has 4 internal disks and I would to assign 2 disks to each VIO.
This is what I was thinking of assigning . Any advise?

Hi
In the vio server when I do # lsattr -El hdisk*, I get a PVID. The same PVID is also seen when I put the lspv command on the vio client partition. This way Im able to confirm the lun using the PVID.
Similarly how does the vio client partition gets the virtual ethernet scsi client adapter... (1 Reply)

roar_vs_file(3) RoarAudio Programmer's Manual roar_vs_file(3)NAME
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.
}
