Long-time alumni know that if you really want to learn something, you make sure you go to a Susan Schreitmueller class. Widely recognized as one of the sharpest AIX guru's around (she's an IBMer), her seminars are always one of the most popular, so you must be prepared to come early and get a seat. Two of her classes that I attended this year:

Integrating NIM and SUMA
First we'll start with NIM and SUMA. As a Unix administrator who has used both tools, I wanted to see what's new and how these systems are now integrated. For those of you not familiar with these systems, NIM is IBM's system for allowing AIX installation through a network, similar to Solaris' Jump Start. SUMA allows you to automate the update process for AIX patches and maintenance updates. Among other announced improvements, NIM can now collect inventory for all POWER5 components. It can also install, update, control distribution and maintain all the images and fixes. SUMA is basically the traffic copy for downloading all the updates.
You can configure polices to include all types of fixes, including specific APARs, critical fixes, fileset fixes, entire technology level upgrades (formerly referred to as maintenance level upgrades), specific PTFs and security fixes.
To now integrate all of these fixes, you would use niminv to gather the inventory of NIM clients and then use SUMA to download appropriate fixes to a NIM master, based on the inventory. NIM would deploy and track the fixes. Niminv would run on a schedule to generate inventory reports of hardware (system and adapter microcode) and software for comparison and tracking, so you can monitor rate of change and track discrepancies in your server farm deployment. SUMA can now even filter against an lpp_source, monitor for updates and notify administrators of critical or desired fixes.
AIX channel opportunities
For the AIX administrator managing a production environment, this is all very exciting stuff. It is also equally exciting for the system integrator who is providing high-level pSeries and AIX consulting for the client. As you know, most of your clients are so busy with day-to-day tasks they don't get out much. When you offer value to the client by providing information or helping support an environment, you'll get a big plus if you're able to proactively recommend solutions. This type of utility integration makes it that much easier to properly administer a customer's environment, which can ultimately help you justify your existence to senior management at the client site.
In the final part of this series, Ken Milberg will cover AIX best practices learned at IBM Tech University.
