A quick follow up on this post about VIOS 3.1.
IBM Champion Stephen Diwell makes some interesting points based on his discoveries during hands-on testing. In this post, he mentions some important things to take note of during the install process, starting with the way paging devices are set up. He also says that resizing your filesystems is a really good idea, and suggests changing the password algorithm from the default.
In a follow-up post, Steve discusses finding ssh host keys included with the VIO server mksysb image, and shows you how to remedy that issue by removing and regenerating the key.
In addition, IBM Systems Magazine has this VIOS 3.1 overview from Jaqui Lynch.
VIOS is an important utility for many of us, so it’s important to know about the potential gotchas as we upgrade to the latest version. As I find more information, I’ll be sure to pass it on.
