How do I tell what version of AIX I have?

(March 2010, valid for 5.3 through at least 6.1)

# instfix -i | grep AIX_ML
    All filesets for were found.
    All filesets for 5300-01_AIX_ML were found.
    All filesets for 5300-02_AIX_ML were found.
    All filesets for 5300-03_AIX_ML were found.
    All filesets for 5300-04_AIX_ML were found.
This tells us that we have AIX 5.3 "Maintenance Level" 4 installed.

Update: Perversely, there's an easier way:

# oslevel -s

(End Update)

Later versions called a "ML" as "TL" instead, for "Technology Level".

This page talks about TL, service pack for TL, and how to download both:

Useful hint:
  • If you want to download a TL and a SP for that TL at the same time, select to download the SP first. It will give you the option to include the TL set in the download at the same time, meaning you only have to deal with one FTP operation.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
