In my consulting work, I see a number of customers with small machines running critical workloads that don't incorporate virtualization. Because these workloads aren't necessarily memory- or CPU-intensive, these customers see no need to set up multiple LPARs. They just want a stand-alone system.

If you use an electronic calendar, chances are you're dealing with multiple calendaring and email systems between your work and personal accounts. Some folks use Google Calendar, others use Outlook and still others use Lotus Notes for example. Personally, I use multiple email clients, and each one has a calendar.

I recently had an AIX LPAR that wasn't booting. In an effort to gather information, IBM Support had me boot it a few different ways. This document details what we needed to do. I'm copying it here because I want to make sure you're aware of this option.

I recently wrote about backups, though I didn't get into the bare metal recovery options for Linux. I wrote about this topic in 2005, and here I am, 11 years later, still wondering where is my integrated bare metal recovery mechanism for Linux? The answer is still going to include Storix, though there's another utility that may also work for you.
