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
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]
A new version of Hardware Management Console code with a browser-based graphical user interface is now available. HMC Version 7 Release 3.1.0 is required to support the recently announced 9117-MMA IBM System p 570, the first POWER6 server to be introduced. This code can also support POWER5 and POWER5+ managed servers, although HMC V6R1.2 with its Web-based System Manager interface continues to be available. (POWER4 managed servers are supported by HMCs running HMC V3R3.7.) The support notice on HMC V7R3.1.0 can be found at this web page:... [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]
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]
Performance concerns on the Hardware Management Console sometimes point to a misconfiguration of the network adapters. In most cases, configuring eth0 and eth1 as either private or open networks using auto negotiation results in no problems whatsoever. But on occasion, the ability of the Ethernet card to correctly negotiate full duplex with a particular switch or router appears to fail and the adapter comes up in half duplex mode. If the switch really is configured for full duplex, the switch may be reporting a problem (or it may go unnoticed)... [More]
Active Memory Expansion (AME) can second in my Top Ten Technologies to be business as usual in the next few years from hundreds of votes world wide. It is available on Power7 machines with AIX 6.1 TL4 SP2 onwards and AIX 7, of course. This allows memory to look at lot bigger than it actually is - to allow more LPARs to be running on a machine or giving headroom for boosts performance. The usefulness of AME is all down to the Expansions Factor (EF) - which is based on the compression ratio achieved for memory pages. If the EF very low then you... [More]
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 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.
HMC V5.2, released in February, allows you to configure call-home to IBM Service using Secure Socket Layer connections. For many customers, this is preferable to using the Internet VPN option. Here are instructions for configuring outbound communication using SSL: 1. Go to the Remote Support menu under Service Applications. 2. Select the Customize Outbound Connectivity task. 3. Connectivity options include Modem, Internet, Internet VPN and Pass-Through Systems. (Pass-Through Systems are i5/OS partitions.) For SSL connectivity, select the... [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 recently announced 7310-CR4 rack-mounted HMC requires HMC V6R1.2 Licensed Internal Code. The reason is that this model introduces new hardware to the product line, and device support exists only in the latest HMC code release. From the abstract in the announcement letter: The IBM 7310 Model CR4 has a Dual Core Intel Xeon 5130, 4 MB Cache, 2.00 GHz, 1333 MHz front-side bus processor, 1 GB of system memory, 80 GB minimum HDD, 12.7 mm DVD-RAM for backup, DVD-RAM media: 4.7 GB single-sided DVD-RAM, type 2 media. Note that there is no IBM... [More]
The fifth POWER Ask the Experts is a one day customer technical event in the UK which ran in Manchester and London on 15th/16th July 2013. It proved to be a very popular free event. We had well over a 100 people attend which was a mixture of customers, a few Business partners and some IBMers.

Systems Director 6.3.1 is available This includes a fix I needed. On a completely fresh install the Update Manager will not work with the NIM server for AIX updates due to a bug that forgets to create /export/um_lpp_source on the NIM server - oops! Fixed with: /usr/sbin/crfs -v jfs2 -g rootvg -m /export/um_lpp_source -a size=1G But make sure it mounts by default on AIX reboot. Find the What's New for 6.3.1 Install the new ISD 6.3.1 update and lots of fixes - you get Systems Director to do upgrade as normal
