I did not grasp what you want to know. MPIO is a feature of AIX 5.3 that permits devices that are accessed via multiple physical paths to be seen as single disks. AIX MPIO is in the fileset devices.common.IBM.mpio.rte and is part of the base OS. Hence there is no need to implement it beside that you install this fileset.

I would like to ask what the benefits are of changing from RDAC to MPIO when connecting to a DS4000 on AIX 5.3? I have heard that IBM MPIO "might" support more than 1 active path to a LUN when connecting to a DS4800 through more than 1 host connection on the same AIX client. I understand that... (8 Replies)

advfs_rmfset
advfs_rmfset(3) Library Functions Manual advfs_rmfset(3)
NAME
advfs_rmfset - Removes a fileset or a clone fileset
SYNOPSIS
#include <sys/advfs_syscalls.h>
int advfs_rmfset(
char domain,
char fileset );
LIBRARY
AdvFS Library (libadvfs)
PARAMETERS
Specifies the name of an existing AdvFS file domain. Specifies the name of the fileset to be removed from the specified file domain.
DESCRIPTION
This function removes an AdvFS fileset from the named file domain.
Once you have removed a fileset using this function, the fileset and its files are not recoverable. The only way to restore the fileset
and its files is by using a backed up version of the fileset.
RESTRICTIONS
This function only removes AdvFS filesets; it does not remove UFS file systems.
The program that calls this function must be running with root privileges.
A fileset or clone fileset cannot be removed with this function if it is mounted.
A fileset that has a clone fileset cannot be removed with this function until the clone fileset has been removed.
RETURN VALUES
The function returns a value of 0 (zero) on successful completion. The function returns a value of -1 on failure and sets the value of
errno to the specific error.
ERRORS
The function sets errno to the specified errors for the following failure conditions: The calling program is not running with root privi-
leges. The AdvFS lock for domain could not be acquired because one of the following operations was already running on the domain: balance,
defragment, rmfset, or rmvol. This fileset is still mounted; it must be unmounted before it can be removed. This fileset has a clone
fileset, which must be removed before this fileset can be removed. An I/O error occurred on one of the disks in the file domain. One or
both of the names for the fileset and the domain are NULL or set to . The file domain specified by the domain parameter does not exist.
The fileset specified by the fileset parameter does not exist in the file domain specified by the domain parameter. There is not
enough memory available for the operation.
