This happens when you remove swap partition from rootvg.
You have to use one on rootvg, since other controllers may not be supported so well by sysplanar0 microcode

leew's link helps with common systems.
I just added practical limitation, that disk upgrades with extra controllers sometimes do not work. (2:1 ???)
