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.
I am posting this as an FYI. I burned a lot of time on digging for this solution. The problem was performance between newer AIX p series boxes and a sun 4500 with a fiber nic. I tried many misc. solutions but this turned out to fix the issue. My bandwidth benchmark went from around 20MB/sec to... (1 Reply)
I have a system model 505 p server. I am trying to virtualize my server. My network admin has given me 10 IP addresses (with the DNS already updated with names that map onto each ip). E.g.: IP1 maps to m1.lab, IP2 maps to m2.lab, etc

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.

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)

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)
