Motivations behind the Chef Client port to AIX

• Many legacy deployments that

work fine – 1000’s of LPARs

not uncommon

• Automate & avoid drift – stop

using SMIT/manual

operations

• Abstract OS for easier porting

to other OSes (primarily

Linux)

Technical Challenges

• Low/no familiarity with platform,

hardware architecture, setup

• XLC - proprietary compiler

• Can’t depend on GNU-isms – bootstrap

systems from scratch

• No real package manager

• Two init systems

• Virtualization features are sometimes

cool, sometimes not

Platform quirks and specific features

• All core Chef resources work out of the box on AIX

• Special resources in core:

bff_package

service – need to specify whether Init or SRC, and some actions don’t work

• More specific AIX resources in aix library cookbook:

Manage inittab

Manage rc.tcpip services

Manage inted.conf services

Change device attributes

Change network tunables

And more…
