Earlier today I received email from a customer reporting their large POWER7 based machines where on firmware 720_64 to 720_90 and their reluctance to take the outage to upgrade it. They were asking for fine details of newer firmware levels and what advantages this would bring to " justify the outage to their user departments ".   To be blunt this is a horror story: I lay awake at night in a cold sweat about stories like this. The customer has the whole "running computers plan upside down".  The question should be " can... [More]

This results in the HMC agreeing to upgrade your POWER7 or POWER7+  machine to firmware level 770, when it is not supported and does not work. This causes very bad problems: On smaller... [More]

I have never really understood why I get peaks and troughs in nmon questions and urgent situations but July seems to be a peak and fortunately I was not at work for a large part of it.  Performance and nmon Questions trend to come in three flavours: really dumb, genuine and mega-urgent critical lets blame the hardware. Let me give you a flavour of each type of question from the last month. Perhaps, reading these will let you avoid the same problem or at least let you learn "you are not alone".   Really dumb "nmon has stopped... [More]

As we all know, the advanced PowerVM virtualisation functions of POWER7 based machines are implemented in the hardware (the POWER7 processor itself and the System Firmware, which includes PowerVM Hypervisor) for increased security, high performance and reliability.  After more than a year of POWER7 field experience and fixes to increase RAS, further development of still more virtualisation functions and improved algorithms for higher performance - it is very important for all of us to install the newer levels of System firmware to avoid already...

OK, this is "blowing my own trumpet" a little but I just finished a 12 minute movie on the best bits of Systems Director. Best in the sense that they "save me a lot of time" and you might like to take a look to see if they can help you too. As I run lots of POWER based machines and lots of copies of AIX, this is why it is very relevant to this AIXpert Blog. The 8 areas are: One Hour Install, Update Manager - HMC, Firmware & AIX  in four mouse clicks, Whole Machine Performance View, LPAR direct to HMC, Active Energy... [More]
