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 fixed problems and improved performance - partilcuarly on larger machines. With the firmware, we also need to update the Hardware Management Console (HMC) to give us access to the features (i.e. turn them on).
The IBM Client Care team are pushing out High Impact Advisory emails to let people know the minimum levels that are recommended for Power 770, Power 780 and Power 795 machines. If you have one of these machine but no email then you are probably not on the Subscription Service - "tut tut" - you should be unless you like sitting in the dark and like getting hit by completely avoidable problems!
Here is the link to the Client Care website and the System Firmware News for Power machines:
Take the Top Right Subscription Service link to sign up to be told of Important Firmware News.
At the moment (and this will be out of date by the time I hit "Post to blog") your machines should be at a recommended:
If you have one of what is called the "C models" that arrived in October 2011:
Also note for planning purposes the developers tell us they are targeting new firmware releases End of January to 740 and End of February for 730.

When I get sent reports of a customer with one of these large machines needing help, the very first question is "What Systems Firmware level are they running?" and to be blunt I getting a little annoyed if the firmware is a long way back level - IBM may have fixed the issue 18 months ago! It is very hard to be sympathetic.

The other key component of PowerVM virtualisation is the Virtual I/O Server
Perhaps, once I have my Shared Storage Pools phase 2 movies ready for download from http
My Power 770 and Power 795 are up to date but that is a little unfair as they are not production machines, I hope your machines will be up to date soon, thanks for listening, Nigel Griffiths
