AIXpert Blog is about the AIX operating system from IBM running on POWER based machines called Power Systems and software related to it like PowerVM for virtualisation, PowerVC for Deploying VM's and PowerSC for security plus performance monitoring and nmon
In case, you missed it : AIX became 25 years old, today . AIX is IBM's name for their UNIX, it stands for Advanced Interactive eXecutive and based on AT&T's UNIX System 5.2 and 5.3. I was not at the launch of the IBM RT (the computer on which it ran) but I know people that were apparently there was a lot of dry ice on the stage. Nor was I with IBM at the time but working for a small software developer company. I do remember, having a loan RT from IBM for porting our software and was impressed with the rugged machine. We weren't given... [More]
Finally, I found the time to try this new exciting feature and it was really simple to create and operate. I captured movie footage of my first attempt and it all worked (once I removed my spelling mistakes in commands). It only took two commands. So the technology has advanced concepts but it really easy to use, COOL! Some of the commands come with long option names like "-custername". A quick misquote from Star-Trek, never goes wrong: "It is UNIX Jim, but not as we know it!" One command to create my cluster,... [More]
We all know that a VIOS level is only fully supported for 2 years ... right! If you have problems with an older VIOS, you may be asked to upgrade to a supported level before a fix can be issued. Most teams run a dual VIOS configuration to allow painless and live upgrades for just this reason. The other reason is to survive a VIOS crash but I have never had a VIOS failure but that would be because I don't go fiddling with them nor adding unsupported software. I quickly upgraded my POWER7 VIOS from 2.1 to the latest VIOS level and made a... [More]
You may have seen comments or even presentations with a few slides on VIOS Next Generation or VIOS NextGen in the past year. I did at the Power Technical Universities and was very interested. Well, the first phase has been release but you may well have missed it as it appears as VIOS 188.8.131.52 FixPack 24 Service Pack 01 - not a catchy title and it slipped out below my radar! It is a regular service pack for the current VIOS and include some other features and fixes too. The first thing you have to note is that only a few features are available... [More]
AIX or VIOS Start-up Memory Problems I have been working with a couple of customers that have a newly setup AIX Logical Partition (LPAR) that fails to start due to not having enough memory. The common factor is that the LPAR for AIX (or VIOS) includes a good number of what I call "high speed" adapters like 10 Gbps Ethernet, or 4 Gbps or 8 Gbps Fibre Channel adapters. They tend to have multiple adapters of each type for redundancy and throughput. For example, trying to start the LPAR with 1 or 2 GB of memory but it turned out they need... [More]
If you are running Systems Director and upgrading to the new version ... WATCH OUT !! Make sure you have 1 GB free space in /var Make sure you have 2 GB free space in /tmp I did not, this upgrade script does not check for free space and it crashed during the Systems Director updating itself (/tmp 100% full) and it never came back. I ended up with a corrupt Systems Director. The smart guys would (before the upgrade) also stopped Systems Director (smstop) and saved the database (smsave) before attempting the upgrade - so the older version... [More]
If you are migrating work from an older POWER5 or POWER6 machine/LPAR to POWER7 ... don't forget to check that those Java versions are compatible with POWER7 or you may hit "unexpected Java errors" The approved Java SDK on POWER7 are limited to particular versions with specific fixes . They can be found here: http://www.ibm.com/developerworks/java/jdk/power7/index.html Harder to check are the Java versions which are embedded in applications. Here are two important ones for IBM software: There is a technical bulletin regarding... [More]
The new November Update is available from the download site from the regular website: http://www.ibm.com/systems/software/director/downloads/index.html When you have 6.2 or 184.108.40.206 installed get Systems Director to update itself - then update the plug-ins via the download site. There is lots of new features and quality improvements too. I will summarise these in a different blog entry. One quick note: if you are doing a fresh install - install DB2 as the database.
I've just told me this is now available from http://www.ibm.com/systems/support/tools/systemplanningtool/ Update to Version 4.10.323.0 (once you have 4.09.323 installed) OK, we have waited long enough so "hurray" its here at last. My colleague in Norway is going to use this to install a very large Power 795 in Norway next week. He is so happy because its going to save him hours and hours in setup time and will get it right first time.
I was asked at the Technical University: How can we tell (in a script) if we are running in a WPAR or a regular AIX? We also called it the Global AIX, if its running WPARs. It took me a good few minutes to find out how to do it and thought I would shared it to save you time: Use: uname -W It returns 0 for the Global AIX and a regular AIX or if it is in a WPAR it returns the WPAR Number (i.e. non-zero) Below we show how to use this in a script. wparno=`uname -W` if (( $wparno == "0" )) then echo Global AIX else echo...

Here are the results from 40 techinical IBMers, 300 people at the Las Vegas Technical University (mostly customers, some business partners and a few IBMers) and 90 more from the same event in Lyon, France. Remember this contains no announcements, the technology is available now and the choice of technology is entirely my own. Voters were allowed to vote for 4 out of the 10 and the results are percentages. All technologies got votes, so there is no failures here, even the lowest scoring one had ~47 votes. My comments: Clearly, Solid State... [More]
I ran this session at the Las Vegas Technical University last week twice. I spend 5 minutes on each of the ten covering the basic concept and the "pro's and con's" then get the audience to vote on their top four. The smaller room took 105 people and the second time in a larger room to 187. It was a BIG conference with 1500+ people attending - its good and encouraging to see so many people interested in Power Systems. The results are fascinating a few top technologies are clear favourites but then the IBMer and customer views are... [More]
Hi, I am preparing for a Power Systems Technical University in Las Vegas, USA and Lyon, France in October. I have a session with the title below and I am seeking feedback from technology guru's like yourselves. Which four of the below ten technologies do you think are "most likely to be normal in five years time"? Please comment on this AIXpert (see "Add a Comment" below) with your four top technologies. I will post the overall results as a graph in roughly two weeks time. Below here there should be a large image of the ten... [More]
I am getting this question quite a lot and the answer is it depends on the model and when it was made available.

Its just not fair that the week I am on holiday so much brilliant software is coming out AIX 6.1 TL06 AIX 7.1 first release Workload Partition Manager for Versioned WPARs (meaning running AIX 5.2) - a Systems Director Plug-in Virtual I/O Server 2.2 Don't forget that for AIX you should also install the first service pack that comes out at the same time. This sweeps up all the fixes between the Gold DVD cut and the actual availability date. The smart guys will be downloading the AIX and VIOS DVDs from ESS (see earlier AIXblog) to get it quickly....
