In Q1 2021 the new version of LPARKit was released. The latest version brings functionality for ‘small’ Power Servers when no HMC, no VIOS is used, and everything related to the LPAR is managed from the Virtual Partition Manager. This version can allow an user to create and manage LPARs or clone the OS from easy green screen interface.
One of the most popular posts on my blog are these related to the HMC, functionality and management. Recently I’ve been invited by IBM research/development team to an adviser role in order to help with improvement the interface. Because at the same time, I realized there are multiple things which were already added with the latest Service Packs but I was not aware of them. I decided to write this post and share the tricks which you may not know.
I assume there are many installations which need to go to VIOS 3.1 by October 2020 due to end of support for VIOS 2.x. Because, I did not find any upgrade procedure for “dummies”, I decided to write one which I hope people find useful. I do not cover only the upgrade process itself, but also share some advises how to do it safely and recover in case of troubles. Upgrade Virtual I/O Server to 3.1 is completely different process than before. For instance, you are going to need an extra disk to perform the operation. Interested?
Long story short – how regular VIOS update ended with few weeks investigations completed with the serious VIOS bug and the APAR (IJ25390). The latest VIO releases contain a serious bug which may affect all VIOS/SEA client LPARs on IBM Power Servers.
I don’t think many people noticed this information yet, but recently a project which I was involved for last two years get live. My feeling is that many people do not understand the idea, thus I created a post explaining the functionality and possible usage. Read more about LPARKit below – tool which allows to create LPARs from 5250 and cloning IBM i OS. Continue reading “LPARKit – tool for managing VIOS from 5250 and cloning IBM i OS”
Finally this is happening! After all these years I’ve been given an opportunity to speak, present, teach others about technologies where I find myself very confident and have experience which should be shared among the community. I will be a speaker at IBM Technical University
This week I discovered very weird bug in the POWER8 firmware. With this bug it is possible to use entire server capacity without paying processor activation to IBM. Continue reading “Demand for extra CPU capacity? Use a bug in POWER8 firmware”
By the command below an LPAR can be created with specific WWPNs, of course if you use NPIV adapters. It can be useful for LPARS migration between servers. It is extremely dangerous command, therefore it should be used only by people who knows what is for. Continue reading “Create an LPAR with specific WWPNs”
In this post I will describe how to create a Shared Ethernet Adapter (SEA) from the new HMC Enhanced GUI interface where no single command in VIOS command line is required. Continue reading “How to create SEA without touching VIOS”
