I have a p520 box running 3 LPARs, 1 x VIOS, 1 x AIX 6.1 and 1 x AIX 7.1 and no HMC, all configuration is performed via VIOS/IVM
Until recently the box did not have the AIX7.1 LPAR and everything was fine with the box.
We needed to use AIX 7.1 for a new project, so I created a new LPAR and configured it to share the non-VIOS resouces equally with the AIX6.1 LPAR. Everything seemed to go well and I was able to install AIX 7.1 successfully and start using that via PuTTy and FTP as required.
However, it seems that everytime we need to cold-boot the machine, the AIX7.1 LPAR looses visibility of the network. The VIOS and AIX6.1 LPARs remain fine with full network connectivity.
In my investigations so far I have found the following from the VIOS LPAR:
