How can you get a scsi card to initalize or decome available at boot up on AIX 4.3
Have a look at this link for some drivers

I don't know much about AIX but I know that you need to work with a similar tool as linuxconf or look around at the /etc/rc*.d/README file,
where * depends of what is your run level.
Good luck
