VIOS 3.1 upgrade for everyone

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?

IBMi – Copy the load-source disk FAQ

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.

I would like to share my experience from implementing and configuring the feature of PowerHA – The Administrative Domains.

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. Read more of this post
