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
Finally, I have the types of memory by POWER7 model double checked. I refreshed the table in part 1 but thought I should make sure every one sees the final version so I have not mislead people. Only the Power 770/780 and Power 797 have Near memory. All the smaller machine operate a Local memory meaning on the same same POWER7 chip and Far memory for any access to another POWER7 chip's memory.
I've updated my nmon2web tool. Its a performance tracking tool for an entire AIX server farm. It can display daily or long term charts. It also aggregates the performance micropartitions residing on the same physical server. You can download it from http://www.aixtips.com/AIXtip/nmon2rrdv3.htm
The USA AIX Virtual User Group have just announced a Systems Director on Power series of live webinar sessions in the next 3 months. Briefly: Starts May 12th 2011. It is delivered remotely, over the Internet, so you can listen in from your desk and watch the slides or any demonstrations with no travelling. It covers the Overview and Basics through to the high function Tivoli Monitoring (ITM) features that are part of the Enterprise Edition of Systems Director. This is delivered by the USA Advanced Technical Skills (ATS) group and I recognise... [More]
That was a shock - right out of the blue, we are told HACMP (OK we should call it PowerHA SystemMirror but life is too short) now supports Versioned WPARs - I had customer questions on this earlier in the week but no idea it was about to be announced. We were recommending using HACMP at the AIX 7 level and treating the WAR as a very well controlled and isolated bunch of processes, file systems etc. as a single resource. But now its much simpler.

We have all heard the old story of a computer company that was so successful that is had to move to smaller premises! The point being that they upgraded the computers to much smaller but more powerful ones and did not need the floor space. Well, it is happening to me! My Advanced Technical Support group are moving from IBM Bedfont Lakes (near Heathrow), UK from building 2 to building 3. That might not sound like much and it is only a stones throw away but we are going from 10 racks down to 3 racks. The old POWER5 machines that were not... [More]
There is a potential problem with AIX display of local time which might occur around the transition to standard time this coming weekend. If the problem occurs, in most cases the only impact is that AIX displays local time incorrectly for a day or so around the transition to or from daylight savings time. AIX displays standard time when it should display daylight savings time or vice versa. Of course, while local time is being displayed incorrectly, if some local time is provided to an application (eg, changing the AIX system clock,... [More]
I have been touring cities in Europe: Birmingham for the 4 day Technical University, Manchester, central London and Dublin for the Ask the Experts 1 day event and last week Copenhagen for a POWER & AIX User group Technical Event. I have had about 250 to 300 people in my sessions and asked every time - How knows about the AIX Virtual User Group and only had about 30 people put their hands up. I am amazed how few people have found this invaluable resource. The organiser, Joe Armstrong an IBMer, set-ups up roughly monthly world wide... [More]
This picture was taken by Shawn Mullen - Security Architect for AIX and cool speaker at the event too. It was taken outside of the Gala Dinner on the Wednesday evening - where we had good food and "interesting" Czech musical entertainment at the beautiful historic Zofin Palace on an island in the main river. From left to right are some of the top speakers at the conference: Ignoring the waiter with the excellent champagne!

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 have long thought it is rather silly that IBM Systems Director can't give you a list the licenses that you should have! It does, after all, know what machines it is controlling and the data is in the database. Perhaps, that will come in the future. What can we do in the short term? Generally, I like to do everything from the graphical user interface (GUI) . I have not got time to learn and use both GUI and CLI. The system configuration data can be extracted using the command line interface (CLI) on the Systems Director server, so I spent... [More]
I highly recommend the AIX Virtual User Group run by Joe Armstrong that roughly has a hot topic Webinar session once a month. Typically, there is 300 to 700 online to the session, many include a demo and there are Slides and Replay downloadable if you miss one or look back over the previous 70 or more sessions and want an update. On the larger hot topics there are lots of questions and answers handled during the session. Officially, it is called the USA AIX Virtual User group but they take registrations from around the world but schedule for... [More]
AIX Security Expert is a system security hardening tool (TCP, NET, IPSEC, system, auditing). It saves time and ensures that all systems have the proper security configuration in an enterprise environment. It was added to AIX5.3 in TL6 (Aug 2006). AIX Security Expert integrates over 300 security settings into a simple menu for selecting High, Medium, Low and Standard security. It also allows you to customize individual settings. It can be used to create a security profile that you can propagate to other systems. AIX Security Expert can be run... [More]
Well it is still early days for this new machine (week 5 from General Availability and there was Xmas in the middle) and I get distracted but concurrently running lots of projects. In this AIXpert Blog entry I am to make some comments on the S812LC OpenPOWER machine regarding Updating Firmware and then Getting the Front Disk Bays working with the simpler RAID Controller (Feature code EC3Y but I am sure the other fancy RAID Controller would be much the same but with fancier RIAD options like RAID5). The development... [More]
This Blog is brought to you by Clive Benjamin (Principal Engineer) who worked out how to do it. If your HMC has a quality high resolution local screen or KVM screen then the Restricted Shell terminal window font size is far too small to read and the font used very narrow lines - in our humble opinion . This blog shows you how to fix this and "no", the obvious window Font Size option does not work. 1) Below: On the HMC start the Restricted Shell window 2) Below: With the cursor on the terminal window used Control + Right mouse button...
