Welcome to AIX for System Administrator!


This blog is intended for anyone who is working with AIX and encountered problems and looking for fast solutions or just want to study about AIX. This is not a usual blog, it is not updated every day. I tried to organize AIX related subjects into several topics, and when I find new info/solutions/interesting stuff I will add it to its topic. You can read here about many things of the world of AIX. (NIM, Storage, Network, VIO, PowerHA, HMC, Performance Tuning...)

The structure of each subject is very similar. First I try to give a general overview about a topic with the most important terms and definitions. This is followed by some important/useful commands, what are probably needed for everyday work. At the end, there are some common situations with solutions which could come up during the daily work of an administrator.

I tried to keep it as simple as possible, so without any further instructions you should be able to navigate through this site very easily.

All of these materials have been gathered by me through my experience, IBM Redbooks, forums and other internet sources. It means not all of them is written by me! If I find an interesting data and I think it is valuable, I publish it on this blog. (Basically this blog is my personal viewpoint about AIX related stuff, and it is not an official IBM site.) Most of the things have been tested successfully but it can occur that you encounter typos, missing steps and erroneous data (I cannot guarantee everything works perfectly), so please look and think before you act.

As I noted above many things have been written by others and where it is possible I try to to list the sources, but to maintain the simple structure of this blog, I'll name persons, whose solutions, suggestions, ideas can be found many times on this blog (or his contribution was very valuable), here in one place.

I would like to say THANK YOU! to

the writers of the IBM Redbooks -- for many many information! (http://www.redbooks.ibm.com)
Nigel Griffiths -- for performance and PowerVM related stuff (https://www.ibm.com/developerworks/mydeveloperworks/blogs/aixpert/?lang=en)

Hi!

I am working with AIX daily and doing expert level duties, but as anyone else can't keep every single command or rarely used theory in my mind. This blog is extremely helpful to remind some things quickly , as well find some new interesting ideas.

I am very appreciative to you for building such constructive and topical blog! Thanks for keeping it alive and continuously improves! ;)

With kind regards,
Andy

Hi

I am preparing my self for AIX administrator interview.

I need your guidance to crack the interview. I have undergone a training of Basic AIX, LPAR, HMC, VIO

I want to know the answer of basic questions

Please provide me answers of below questions.

Q how many CPU, memory and disk can be available in power 5, 6 and 7 series with oracle data base of 200 GB?

Recomended CPU (processor) Memory Disk HMC versions
Power5 ? ? ? ?

Power6 ? ? ? ?

Power7 ? ? ? ?

Q. what are the steps of migration from AIX 5.3 to 6.3?

Q what are the difference between TL (technology level) and ML (maintance level)?


Thanks in advance for sharing above information.

jatin

aix said...

Hi, for CPU and Memory questions please use Google. Steps of migrations can be found in NIM -> NIMADM section. TL and ML are the same, earlier it was called ML, and after some time IBM decided to call it TL.

Hi, to be honest, I tried to register with AdSense 2 years ago, but this site was rejected (probably because I changed a lot on the Blog template.), but I think it is more professional this way.

We run 2 different Terminal Emulation programs. After a recent power outage, neither program likes the AIX server anymore and aren't on speaking terms. Working on the server itself is fine. Any suggestions? Keep in mind, I have no clue what to look for since what I know about AIX is zero.
This is a great blog , BTW, even though I have no clue what 98% of the info means...

Just wanted to send my thank you to this blog. It saved me from having to comb out google and paper docs just to find a single command or option. Been doing AIX for almost a decade now and I still rely on this site for quick fixes, or something that needs validation before hitting the terminal

aix said...

Thanks eikkin :) Actually I do the same, if I have doubts I check things here fast before I do something :)

This is one the best blog site available for AIX admins, I have learned a lot from this site I'd like to convert this blog into book and keep handy for reference.
