Use the AIX install/maint diskettes to delete all of the AIX
minidisks.  I believe that you want Utility functions off of the main
menu.  Then use the VRM minidisk to "Change Page Space Minidisk".  You
can do it all from the VRM diskette, but it is not obvious.

Then do the install with the Install Maint diskette.

I've successfully moved /usr by creating a new partition, backing up
and restoring the data to the new partition, and then using the
Install/Maint diskettes, deleting the minidisks and reallocating them
in the exact same locations but with the opposite IODN numbers.  But
you can't count this as "while AIX is running", since it has to be
done from install/maint.
