I am guessing that the two versions of VIOS and AIX do not communicate with each other. They changed the names of the lsrsrc components.

I expect if you can get your AIX 5.3 updated to at least TL7 (best guess, there were a lot of changes to bring AIX 5.3 in line with AIX 6) it might work.

command I use to see what is known is:

Code:

for i in `lsrsrc | grep IBM`
do
lsrsrc $i
echo
done

One of these should have related information. But basically, my gut says the client does not know how to converse with VIOS.

Not recommended!!! Or - Install a 1.X VIOS. I think it is easier to install/update one partition and see if it works then than go backwards with VIOS.
