IT Jungle has posted my current article on properly prepping for an IBM i IPL by creating and using an IPL Startup Kit.
I cover the following territory in this article:
To help prevent surprises, here’s an IPL startup kit that you can put together and use before and after your next IPL. The kit can help you look for items that need to be added to your system startup routine. It can also help you find items that should have been restarted during your IPL but weren’t.
This was inspired when I recently got burnt IPLing one of our Power 6 partitions and some things stopped working that had been working, pre-IPL. So hopefully you can learn from my experience and mitigate some of the risks involved in an IBM i IPL.
