Recently I was asked how to execute a command typed in 5250 terminal among multiple sessions. For instance, when you need to create a library DEV on three systems, and you are lazy do copy/paste.
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”
How many of you are missing the old classic HMC GUI? Since version V8R8.7.0 we can run only new Enhanced GUI+ interface. Thus, POWER9 machines can be managed only by the Enhanced+ interface, right? In this post you can find a procedure how to start the classic GUI. even on the HMC running latest FW9.1. Continue reading “Enable classic HMC GUI on release V9R1 – locked with HMC fix”
Process for copying the load source disk is sort of a black box. The copying process is straight forward, but there is no documentation ‘what if’. My assumption is because this is very sensitive operation, IBM does not want us to meddle with the process. I’ve created sort of summary for admins based on my experience ,and research made over hundreds copying processes. I bet you won’t get this information thru any official channel.
Me and many other technicians hate the limitation that the only supported way of migrating the Loadsource disk to a smaller LUN is save/restore IBMi OS. With the method described below, I was able to copy the Loadsource to the smaller disk, and it worked. Continue reading “IBMi – copy the loadsource to a smaller disk”
