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
Four things I think you should know before you try this: The documentation for the update can be found here: http://www-01.ibm.com/support/docview.wss?uid=hpc1vios117f5701 I updated three of my Virtual I/O Servers to 184.108.40.206 from 220.127.116.11 over the weekend. I started these late on Friday night with the "no reboot" options and they finished about the same time on Sunday afternoon i.e. 48 hours . The Release Manager downloads the update directly to the VIOS /opt/VIOS/update/VIOS and sub directory for the release name and this takes over... [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! Jay Kruemcke - Power Software Program Director, USA - Mr AIX to his friends - twitter: chromeaix Patrick... [More]
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]
We needed to install AIX 5.2 in order to create a mksysb for AIX 7 Versioned WPAR testing - this allows you to run AIX 5.2 in a WPAR. First we had endless problems locating media but our Computer Room Manager Mike turned up trumps in the end - he keeps everything and regularly saves the day. So we loaded all 7 CDROMs on to our VIOS to add them to the virtual Optical Library. Second, we booted from the CDROM only to with an immediate halt with a warning the AIX 5.2 can't run in a Shared CPU LPAR - doh! we should have realised that one. It was a... [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 18.104.22.168 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.
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]
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.
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.

I just noticed the rPerfs (relative performance numbers) for the four new Entry Level systems (Power 710/720/730/740) and the High End Power 795 are available in the updated "Power Systems Facts and Features" document on the IBM website. My notes: The Entry Level machines are now 16 core/CPU/way (delete as you like to call them). That is a serious machine for the bottom end 2U rack server and it has all the POWER7 virtualisation features built in. These humble machines have the roughly the same performance as the mid-range previous... [More]
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]
At a recent POWER & AIX Workshop, I was challenged when I stated that you can download IBM Systems Director (ISD) and run it at no costs. Granted: If you want IBM Support for ISD functions then you do need to purchase the license and SWMA for every endpoint (think HMC and every core of any machine that ISD is controlling). Compared to other systems management tools (I have worked with in the past) the ISD prices are very low so its worth asking for the local currency price. I also think most people (including myself) will get stuck on... [More]
Just a quick look at the features for AIX7 - which is coming soon. Take a look at AIX7 Preview for an official statement. The two major items for me are 1) Scaling to 256 cores (or CPUs as I have called them for 25 years) Power systems always had lower CPU counts than the competition particularly in the high end machines due to the faster speed of the processor and this benefits batch (single threaded) work, software costs (lower CPU numbers) and is easier for scaling up but now a truly massive POWER7 machine is near and AIX7 is the OS to run...

As part of my moving computer room project, I had to change the IP address of my Systems Director server. I recall a long time ago there were issues in this area for (I think) ISD 6.1, so I was not looking forward to this change. Just for a change, I thought I would check the documentation first :-) Once I found the 6.3 part of the documentation there was a whole page on how to do this IP address change. It turns out to be very simple on ISD 6.3. Stop Systems Director with: smstop Change the IP address and DNS server, of course, to match.... [More]
Hot news this morning is IBM announcing the updating of the Lower End Power 710/730 and Power 720/740 models to include Power7+ processor with 2.5 larger L3 cache, Active Memory Expansion accelerator, and GHz boost Double the memory size This gives a large performance boost and drastically higher "bangs per buck" as the Americans say or "Value for money" as we Brits say. Almost everything else is the same so if you know the older models it is easy to understand Announcement letters for the new Power7+ models: Power 710 ,... [More]
IBM Systems Director 6.3 Arrives Early Yes, you read that right - it arrived earlier than the date in the IBM Announcement - a free to use unexpected Xmas present from IBM. I have never heard of an early delivery before - perhaps I am getting to old and cynical :-) The Base Server download for AIX is a larger 1.9 GB file (was 1.3 GB for 6.2) but that includes includes AEM,VMControl (and Service and support manager but we probably don't need that as we have the function in Power Systems via the HMC). They all get installed in one go but you... [More]
