I am "Sys Adm" for a small co.
We have a 8203-E4A machine and I have previously managed to setup a VIOS and IVM and AIX 6.1 partition. This process was new to me and it took me some time to get right, and that was about 3 yrs ago.
Last week I created a new Partition to run AIX7.1 and all was going well. I created the partition, was able to mkvt to get to the console and install the OS. I was then able to access the partition instance via PuTTy and continue with my work of installing our s/w packs, e.g. XL C/C++ etc.
The next day I was unable to connect to the 7.1 partition via PuTTy or to ping it from the 6.1 partition. I started looking at the network configuration to try and determine what had caused IP access to be dropped, but couldn't see anything obvious, so I started doing things by trial and error and ended up with no IP access to either partition.
I am not sure what I changed, but now I need help restoring things.
I have no HMC as this is a stand-alone machine. I can access the ASM via web interface and Serial Cable, but can't do anything more.
Help... please... Let's assume I am a novice, so be kind...
Re: IP access lost to machine2013-01-28T14:57:25ZThis is the accepted answer. This is the accepted answer.It turns out that I had the Serial cable plugged into the wrong serial port and therefore I was never seeing the console for the IVM after restarting the machine. Once I found this page http://pic.dhe.ibm.com/infocenter/powersys/v3r1m5/index.jsp?topic=/p7hch/iphchconnectlpm.htm, I could successfully login to the IVM Console and issue a few commands:
lsdev -type adapter (showed me which was the virtual Ethernet adapter)
mktcpip (with parameters) let me redefine the IP settings for the adapter)
Once that was done, I could then see the IVM Web page and change the two lpar ethernet sttings via the GUI interface.
All back up and running and able to connect via PuTTy to both lpar's
