AIXpert Blog is about the AIX operating system from IBM running on POWER based machines called Power Systems and software related to it like IBM Systems Director, PowerVM for virtualisation and PowerSC for security plus performance monitoring and nmon
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]
It has been a busy fortnight and I just realised I have micro-blogged (Twitter) comments and link but neglected this AIXpert Blog - sorry about that. Here is a summary and a lot more thoughts that Twitter allows. I actually like the discipline of the Twitter 140 characters as if forces you to get to the point!
Firefox First, I have upgraded to Firefox 10 Enterprise from 3.6 - I was having multiple problems with the older release that had previously seemed to be the only safe one for using both HMC and IBM Systems Director. In particular,... [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]
At the Miami and Copenhagen Power Systems Technical Universities, I covered what we knew about the next release of Systems Director (6.3) planned for 16th December 2011. One of the hot topics was High Availability using disk replication for the embedded DB2 database for active:passive fail-over. It turns out this feature is not included with Systems Director 6.3 release - sorry about that. The good news, at least, is that this feature is in development and working for the next release of SDMC, which is based on Systems Director 6.3... [More]
In case you missed the announcements, I have released four new movies this week: Shared Storage Pools phase 2 - Getting Started - movie 101 Active Memory Deduplication Theory - movie 102 Active System Optimizer - movie 103 System Director 6.3 First Use - movie 104 Catch them all at the home of POWER6, POWER7, PowerVM, Systems Director and AIX Movies - or save this link for 21 hours of intensive techie learning - http://tinyurl.com/AIXmovies ps: The previous movie last month about installing Systems Director 6.3 on AIX is a good movie...

This is an odd blog - it is about the withdrawal of POWER6 - which was announced in stealth mode! It has come as a shock to some customers. Given POWER7 comes with vast improvements in price performance you might say: Who cares and who would be buying POWER6 anyway? Well some customers with long term roll-out plans, need consistent equipment for reduced complexity and reduced testing and so still want POWER6 and could get caught out. So if you care, here is my list of withdrawal dates after which you can't buy new machines (nor POWER5 to... [More]
I am preparing sessions for a POWER/AIX Technical Conference in Norway - unfortunately the only place they could book for the event was a Ski Resort up in the mountains and there is still good snow. It is a tough gig but someone has to do it :-) As part of that conference, I am updating them on Systems Director and demonstrating it. I had a slide with these hints and tips. A slide with zero percent marks for style (far to many words and just a long list) and I thought ... I should share these with everyone, so here they are. Most of these are... [More]
Hints &Tips for Systems Director 6.2+ for AIX on POWER (Part 2) Here are a few more hints and tips - you can find Part 1 HERE 23) Excellent document on getting Systems Director running faster or starting with the right resources The document "Performance Tuning and Scaling Guide for IBM Systems Director 6.2.x" can be found at: http://tinyurl.com/SDperformance 24) Systems Director supported SAN Disks + Switches matrix can be found at http://tinyurl.com/SDdisks This explains the way that various disks are connected to Systems...

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]
I thought I should summarise the long eleven part Local, Near & Far POWER7 Affinity series. 1) Placement: Find out the layout of your boxes CPU and RAM and if the RAM is evenly distributed across available DIMMs Find out the placement of your Virtual Machines (LPARs) with lssrad -av - or - topas -M 2) SMT4 : Expect POWER7 SMT4 CPU use to “look” different POWER5 & 6 have two equal threads POWER7 shuts down threads 3 & 4 and even thread 2 - when there is not enough processes running. 3) Entitlement : Only set minimum Entitlements,...

I have been wondering why the lower end POWER7 machines have local and far memory and not local and near. Perhaps you wondered too! Well at the Miami Power Technical University, I got to talk to Dr Joel Tendler (IBMer) and a POWER7 processor guru and put the question to him. He covered this sort of architectural topic in his presentation at the event and I learnt a lot in this area by listening to the "master". Below is some background and the explanation too. The POWER7 chips has two memory controllers for maximum performance but... [More]
With Systems Director and VMControl Standard Edition (this was called Image Manager), you can Capture an AIX Virtual Server to an appliance in the VMControl Repository. Then later Deploy the appliance to a new Virtual Server on a different Power machine. What this means in proper technical "AIX speak" is Systems Director can: Create a mksysb to a NIM server and also save the LPAR settings (numbers of CPU, RAM, network and disks). Later you can perform a NIM client install from the mksysb and it automatically uses the same LPAR... [More]
There were a number of announcements made today by Power
Systems including new hardware features, a new platform management console, and
new PowerVM virtualization capabilities.
Two new Power Systems blade servers were announced, the PS703 and PS704 . The PS703 blade supports up to 16 processor cores in a single
BladeCenter slot and the PS704 supports up to 32 cores in a double-wide
blade. The PS703 and PS704 also support
a new solid state drive option.
The Power 750 Express server has new processor options or 4, 6 or 8
Hi, I am just back from the Prague Technical University last week. Everything worked well at the conference at the Hilton and the sessions were excellent - even the ones that I ran :-) but I keep making one mistake ... I volunteer to give an extra session or two. I ran the following sessions: Systems Director Lecture for AIX/POWER Users This covers the basics for a techie that needs to get it running including the architecture/components, pre-requisites, Advanced plug-in selection, The Systems Director Editions for reduced cost, compared...

I have indirectly been getting copies of this 4 page, .PDF, once a quarter, Power Systems Newsletter written by Richard Milton (an IBMer in the USA) and every time found a few "Wow! That's Cool!" items in it. I just checked with Richard and he says anyone is free to sign up to the email list and you will get it emailed to you once a quarter. I have signed up. Needless to say, it is for Techies and not marketing fluff but has a couple of one page quick details of particular products and experience and comments on them. Then there... [More]
