IBM: Big Data, PureData Systems for Hadoop
Introduction to Big Data. What is it?: Analyse all kinds of data: Large volumes, valuable but difficult to extract, time sensitive. Multiple devices - systems, mobile devices (phones, tablets, gps), smart meters, RFID tags and more. Multiple feeds - website, social media, DBs We need to make better use of the data we have, year on year the amount of data available increases by huge amounts.

POWER NPIV - Quick & Dirty
Over the last few months working with IBM PowerVC I've had to get used to using NPIV, not my first choice of virtual storage adapter due to its large memory footprint (130Mb per adapter compared to vSCSI for 1.5Mb). But given its ease of use for PowerVC allowing my colleagues to deploy IBM Power servers without me, it more then makes up for this. When I initially started using NPIV it took a little while to get the adapters set-up, a number of documents that I followed made some assumptions. This meant that I was looking at more then one...

HMC - VIOS install error: "Error reading nimol"
Re-installing a VIOS today to the latest version I hit a issue, it was that my HMC was complaining a server with the same name was already installing. The message was 'Install Virtual I/O Server Failed - <name> Error reading nimol configuration. The client "<name.domain>" already exists.' As you can see from the image below: It would seem that this is a bug with HMC 7.7.8.0, in that if you have ended a install before it completes, some of the clean up doesn't get done. Fortunately there is a... [More]

IBM PowerVC - Errors
If you see the following error, then like me you might be wondering what the issue is - U nable to connect to HMC <hmc-name>. AEVCOM021E Explanation: Connection failed to the Hardware Management Console. Response: Review the explanation and try the request again. It would seem that PowerVC has performed more stringent checking then I have, and in this case it doesn't like my HMC, its a model 7042C06. If you have been paying attention and looking at my previous blogs you will see that the supported models are CR5/C08 or... [More]

IBM PowerVC install
So I've done the first part of my PowerVC set-up, in this case install of the base code onto the Redhat 6.4 system I prepared. If you're not sure how to do this then I have a number of related articles that cover setting up the repositories, IBM Power Tool, and the networking. So be sure to have a look at those before you get started then you know you have the right packages on the image: IBM PowerVC: First you need to put the base code on the system, so find the package: gzip -d powervc-install-ppc-rhel-1.2.1.0.tgz and get...

VIOS Shared Ethernet Adapter Offline
So all of your virtual machines (LPARs) have gone offline and you can't contact them any more, but is your VIOS still on the network, so what could be the matter? In my case the 'Shared Ethernet Adapter' on the VIOS has gone defined. So logon to the VIOS via the console and lets check the state of the adapters: padmin $ lsdev -type adapter name status description... [More]

IBM 10 Years Service
Got presented this pen today for my ten years service with IBM, which is funny as I joined IBM in 98, not 2003. This works out as my total years service with IBM, rather then my start date as I've left and returned to the company twice. Its nice that they count it all together, along with this I got a extra days holiday a year as you get a day for every 5 years service. As for my time working with UNIX and such I think I'm in my 20th year now.

Re-installing the IBM PureFlex™ System and IBM Flex FSM.
So you have broken the FSM in you IBM Flex or IBM PureFlex™ System, either it won't power on any more, or its just failing to start. In my case after a software update it wouldn't boot up correctly and some how the root user had been corrupted, so this meant that I couldn't get access to the system. Below I'll go through the steps I took to get the software re-installed from the 'recovery' section of the internal disk on the FSM node. First you need to log into the CMM (Chassis Management Module) in order to reset the FSM node - Once... [More]

DOS to AIX conversion
DOS to AIX Conversion I got asked about this today, so I figured I best keep a few notes hand for anyone else that might need this while also keeping it handy for myself. awk awk can be used to convert a DOS file to Unix - # awk '{ sub("\r$", ""); print }' dos.txt > aix.txt You can also use it to convert it back the other way - # awk 'sub("$", "\r")' aix.txt > dos.txt Perl You can also include this directly into your perl scripts as frollows, so to convert a DOS file to a AIX - # perl -p -e...
