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 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”
Today, I want to share my experience with the upgrade an SR-IOV adapter firmware (EN0H) configured in shared mode. The update was so simple and so straight forward that I decided to share this positive message with you. Continue reading “SR-IOV firmware upgrade via the HMC Enhanced GUI”
The other day, I’ve wrote about POWER8 ‘feature’ which requires from an administrator update of access keys in order to keep a server eligible for the firmware upgrade POWER8 – No hardware maintenance-no firmware upgrade . An administrator needs to enter these every few months, if a maintenance contract is re-signed every few months. This can be a headache, or something bigger if someone runs multiple servers. There is a secret HMC function, which can update the keys automatically.
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”
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”
There is a very simple how to submit any IBM i command across multiple systems. The main requirement for it is the Management Central. Continue reading “Perform a command across multiple IBM i systems”
Today, I was preparing another program for automation. I need a function to retrieve an IP address of a remote system from the DNS having the system hostname. In the interactive session, you’d simple use ping or nslookup commands to resolve the hostname. But none of these commands can store the result into a variable. I did a short research, and there is very cool command Start DIG Query (DIG). This command can be used in a program, and it’s very easy get an IP address. Here is the example of a simple CL:
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.
