AIX tech tip: a tribute to AIX devices
When you have a device connected to AIX, such as a disk or a tape drive, you can discover it using cfgmgr. As you’d expect, it will have the default parameters that are used for the device driver. Sometimes you’ll want to change these parameters – usually to allow you to tune the device for…

How to use the SVC/Storwize CLI
Over the last five years, I have worked with both SVC and the Storwize Vxxxx family of products with IBM i and AIX on Power Systems. SVC and Storwize share the same software stack and GUI. There are some functions which are only available in SVC but, predominantly, the configuration and management is the same.…

AIX tech tip: How to scan new devices with a single command
There are things I really love about virtualisation for Power Systems. I probably appreciate some things more than other people do because I got to see how things used to work many years ago. A combination of physical and virtual enhancements has made life a lot easier than it used to be. I remember when…

Five reasons to love your Hardware Management Console
For a while, I’ve noticed that most IBM i sites that have Hardware Management Consoles (HMCs) don’t seem to show them much love. In fact, in many cases I would go as far to say that they actively go out of their way to ignore them. If you have an HMC, ask yourself one question.…

How to get started with PHP on Power i
Why would you choose to start using PHP on your Power i? Well, if you are thinking of delivering applications in a browser – either on a desktop PC or mobile device – PHP is an ideal choice. It is built for the web. In fact, vast swathes of the web are written using it.…

How to take advantage of the new, smaller IBM i 7.2
With the release of IBM i version 7.2 Technology Refresh 1, Big Blue has reduced the size requirement for the load-source disk for virtualised storage implementations. “So what?” I hear you cry. “All my disks are physical, they are bigger than 70GB and have been for years. What’s the big deal?” Well, for production workloads,…

Masterclass: advanced vSCSI disk monitoring (includes scripts)
In my previous article, I showed how you can use nmon in VIOS to display the performance statistics of hdisks that are mapped to client LPARs. This is achieved by creating a file which nmon reads and then displays the relevant performance data. The script I used required that the virtual target devices (VTDs) mapped…

Can free-form RPG catch on?
Ah, my first article for PowerWire! I hope that the editor chose me for my RPG knowledge, not my photo on LinkedIn (go on, take a look). My experience of RPG goes back to RPG II on the System/36 in the early 1980s. I’m sure a fair portion of you can say you go back…

7.2 things I love about IBM i 7.2 (part 2)
It’s hard to believe it but 2014, the year that brought us v7.2 and Power8, is almost over. Indeed, it may well be gone by the time you read this. So, without further ado, here is part two of my list of things that I love about version 7.2 of our favourite operating system. Number…

Is the new HMC interface enhanced or not?
IBM has rather quietly brought out a new interface to its Hardware Management Console (HMC). This became an option in V8R8.1 Service Pack1 of the HMC. IBM has called it the enhanced interface and you will have an option to select it at log in. Don’t worry, you’ll know it when you see it. Before…

How to monitor client LPAR vSCSI disks in VIOS
Many customers use vSCSI disk-mapping in VIOS to present external storage volumes to their client LPARs. There are proponents of vSCSI, NPIV and Shared Storage Pools. These all work very well. I find that AIX-minded technicians will lean towards NPIV because that’s what they have used traditionally. IBM i technicians will tend to use vSCSI…
