IBM AIX VIOS IVM Ethernet problem
Hi All,

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:
Code:

et6              Defined     IEEE 802.3 Ethernet Network Interface
et7              Defined     IEEE 802.3 Ethernet Network Interface

I can activate the AIX7.1 LPAR and watch the boot process via the IVM Web interface's Java Console facility. When I do this, the boot is very slow and eventually reports the following messages (full boot console dump in attachment):
Code:

 id.

I cannot see anything else wrong with the configuration, but then I am not an expert in these things.

In summary, I have a p520 box; 3 LPARs and no HMC; I use VIOS/IVM for configuration changes; one LPAR looses ethernet access when the box is cold booted.

I am the "part-time" Unix System Admin in a small company (not my main role in the Co.), so detailed help would be appreciated.

Thanks in advance
