What happens if we perform a Native AIX TL Upgrade on a VIO server? I mean instead of updateios I logged into oem_setup_env and ran a update_all to a new TL.
Perhaps this tutorial will help you?

It may not be helpful, but just in case.... please take a look.
Any ideas about my problem. I know its unsupported method. But any ideas would be appreciated.
