Back in the day, downloading of a server firmware from IBM Fix Central website was limited only to users and serial numbers with valid IBM hardware maintenance contract. With POWER8 servers IBM put such a lock into the servers. Thus, if your hardware maintenance contract expired, you cannot install any newer firmware beyond this date. Read more of this post

Dynamic Platform Optimizer is a hypervisor function which rearranges logical partition processors and memory on the system to improve the affinity between processors, and memory of logical partitions. In this post I will describe when to use this function and how to prevent IBM i Lpar from crash. Read more of this post

I would like to bring to attention installation order of fixes for the HMC firmware 8.8.2. If you install the fixes in incorrect order, you might loose the RMC connection to all AIX/VIOS hosts.

In my previous post I’ve mentioned about the new HMC feature which can adjust CPU frequency. In this article I want to describe how to speed up the POWER system box, get more performance from the system. It is very easy to overclock the machine.

Few hours ago IBM has released the firmware which enables the SR-IOV functionality on E870/E880 servers.

- Feb 24th IBM finally announced SR-IOV support for enterprise POWER8 models (E870, E880).
- If you run workload on a MMA/MMC/MMB/MHC/MHB/595 server, and you are thinking about upgrade to a POWER8 model, you have only 9 months to go. Otherwise, you will lose your serial number!

In this post I give you a hint how to display a log which is usually used by IBM support to identify a serious hardware error. Such information usually can be found in HMC log called iqyylog. Usually, when you get that kind of hardware error, you involve IBM support. Very likely, they will ask for PE debug data. There is a way how to display the log by yourself. Remember, such information is very technical. But maybe you find it useful.
- First, you need to create the hscpe account on the HMC (if you haven’t done it). You can find the process here.
- Log in to the HMC GUI under hscpe account.
- In the Service Management menu you find three new options available
If you click on View Management Console Logs, you are going to see the log.
