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.
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”
Last weekend I had a very unpleasant situation. A server reboot made an entire machine unusable. It was very difficult issue, costing an unplanned outage. Actually, we had all series of unfortunate events that day. I got aged by few years, but also learn there is always a solution, event in a hopeless situation. Read the entire story to avoid a similar problem. Continue reading “How to prevent situation when server IPL may affect SAS controller”
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”
Those of you who run recent hardware, probably noticed the new HMC interface called Enhanced+ GUI available since the HMC Firmware 8.8.1 SP1. In this post I would like to share my point of view and give some advice for people who would like to use it. Continue reading “My few words about HMC Enhanced + interface”
Nowadays, I’m preparing for huge hardware delivery. I’m about to get dozen of MMD’s. The challenge is to configure them (LPAR profiles, VIOS, etc) as soon as possible. I found the way how to automate creation of multiple VIO/LPAR profiles including I/O configuration for multiple servers without knowing SN of the expansions drawers.
