I am guessing you meant AIO as in Asynchronous I/O. If so AIX 6.1 enables AIO dynamically.

If you really meant aioo then if it's related to AIO maybe something here will help.

vfs_aio_fork
VFS_AIO_FORK(8) System Administration tools VFS_AIO_FORK(8)
NAME
vfs_aio_fork - implement async I/O in Samba vfs
SYNOPSIS
vfs objects = aio_fork
DESCRIPTION
This VFS module is part of the samba(7) suite.
The aio_fork VFS module enables async I/O for Samba on platforms where the system level Posix AIO interface is insufficient. Posix AIO can
suffer from severe limitations. For example, on some Linux versions the real-time signals that it uses are broken under heavy load. Other
systems only allow AIO when special kernel modules are loaded or only allow a certain system-wide amount of async requests being scheduled.
Systems based on glibc (most Linux systems) only allow a single outstanding request per file descriptor.
To work around all these limitations, the aio_fork module was written. It uses forked helper processes instead of the internal Posix AIO
interface to create asynchronousity for read and write calls. It has no parameters, it will create helper processes when async requests
come in as needed. Idle helper processes will be removed every 30 seconds.
This module is stackable.
EXAMPLES
Straight forward use:
[cooldata]
path = /data/ice
vfs objects = aio_fork
VERSION
This man page is correct for version 4.0.0 of the Samba suite.
AUTHOR
The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
Source project similar to the way the Linux kernel is developed.
