AIX Instalation pre-req (5.3 and 6.1)

Just some pre-req that I do in my AIX installations (I use some necessary Oracle reqs, just in case):
Ok.. just a warning, use at your own risk (all tunings are oracle and ibm based, so I'm not responsible if you mess the things up). After that, ask your customer for some different tunings, if needed.

1) Verifications

* Gather all necessary information, such network configuration and partition configuration (if any specified) to accelerate the process.
* Verify connections, cables, plug everything and take a look if display some error codes.
* Verify if will be necessary some activation after the start-up process.

2) Install options
