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:
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):
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.
So, I'm assuming that VIO/IVM is installed and owns all the hardware and the other partitions a guests rather than hardware partitions. That's what I have too.
There may be an issue with running an IVM based on AIX 6 with guests of AIX 7. Are you able to get to the shell prompt?

you would be best checking with IBM about supported configurations. It may be that you need to upgrade the IVM first, which might have an impact on you running AIX 6.1 partition. At the least, it will reboot, but I would be more concerned about any co-requisite updates your partition will need.
I have a serial console cable connecting my Desktop to the p520 box and am therefore able to get to the VIOS LPAR via HyperTerminal. From that I can also get to both AIX LPARs using the "mkvt -id x" command

There is nothing wrong with your VIOS level for doing what you want to do.
The most likely cause is that the virtual interface you defined is not on the shared ethernet adapter. The slow startup is probably being caused by DNS timeouts.
To speed that up add:
Code:
RES_RETRY=2
RES_TIMEOUT=2
the the end of your /etc/environment file.
I have been supporting AIX 5.3.X, AIX 6.1 TLX and AIX 7.1 TLX in many combinations on p51a for years, and recently on a p505.
p.s. - there are newer versions of VIOS (2.2.2.something now) but that has nothing to do with your problem. And VIOS is on AIX 6.1 by design (AIX 6.1 may even live longer to prevent any forced update of VIOS to AIX >6).

The most likely cause is that the virtual interface you defined is not on the shared ethernet adapter.
How would I confirm that is the problem and then fix that if it turns out to be the case?
In my mind I think that there is a 1:1 relationship between physical ethernet adapter ports and LPAR connections, but I guess this might not be the case.

Hello,
I have some unclear about how VIOS uses its resources.
Assume that VIOS lpar has only 1 physical FC, and we use that to connect to the Lun. Then we install VIOS for the lpar on that Lun.
So my question is, afterward, we can still use that physical FC for the virtual FC we create... (3 Replies)

I am facing problems in moving CD-ROM from one lpar to another.
CDROM can be seen on the POWERVM (IVM) server , but through the web-access if I move it ( assign it ) to LPAR it will be assigned. I run cfgmgr , and the cdrom does not show up in the LPAR. I firmly believe this is the reason why I... (2 Replies)

Hi everyone,
Sorry if this post is in the wrong place. I searched the forums for "IVM" and it turned up no results. Hopefully someone knows about this.
