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.

rmfset(8)						      System Manager's Manual							 rmfset(8)

NAME
rmfset - Removes a fileset or a clone fileset from an AdvFS file domain SYNOPSIS
/sbin/rmfset [-f] domain fileset OPTIONS
Turns off the message prompt. OPERANDS
Specifies the name of an existing AdvFS file domain. Specifies the name of the fileset to be removed from the specified file domain. DESCRIPTION
The rmfset command removes a fileset (and all of its files) from an existing AdvFS file domain. Unless you use the -f option, you are prompted with the following request before a fileset is removed: rmfset: remove fileset <filesetname>? [y/n] If you answer n, the fileset is not removed. If you answer y, the fileset is removed. The -f option is useful for scripts or when you do not want to be queried about each fileset. If you choose the -f option, no prompts are displayed. The rmfset command operates as if you responded yes to the prompt. Unmount a fileset before removing it with the rmfset command. RESTRICTIONS
A fileset or clone fileset cannot be removed with this command if it is mounted. A fileset that has a clone fileset cannot be removed with this command until the clone fileset has been removed. You must be the root user to use this command. An rmfset operation can hang if you attempt to remove a fileset and the target AdvFS domain is experiencing heavy I/O. To work around the restriction, avoid using the utility on busy AdvFS domains. EXAMPLES
The following example deletes the test_fset fileset from the test_domain file domain. In this example, the test_fset fileset is mounted on the /mnt3 directory: # umount /mnt3 # rmfset test_domain test_fset rmfset: remove fileset test_fset? [y/n] y # SEE ALSO
Commands: mkfset(8), showfdmn(8), showfsets(8), mount(8) Functions: advfs_rmfset(3) File Formats: advfs(4) rmfset(8)
