I was convinced to start using Emacs Org-mode back in January, and have not regretted it. Still learning, and there is much to learn, but I have the basics down.
As I manage some IBM Spectrum Scale (ESS) GPFS clusters, and I was facing the dreaded task of upgrading them, I decided to create an Org-mode plan as I went along.
Always remember that IBM publishes an ESS upgrade document for every specific version, and that must be followed, but this Org-mode plan stream-lines the process and helps you keep track of process and makes sure you don’t miss a step. It comes with commands and URLs to help you with each task.
This Org-mode plan is specifically for an online 5.6.3.2 upgrade on a PPC64LE system without HMC.

Hope it helps.
