You need an install CD. Seach comp.os.aix for "Lost root password" or
similar for directions. You'll need a copy of AIX 4.x install media
for this, using a newer or older version likely won't work.

If the drives are internal, and connected to the motherboard, then yes.

If you want to get a hardware inventory, but don't have root access yet,
you can turn the keyswitch to "service" mode (all the way clockwise),
and boot it up, and then find the correct menu item (I can't remember
the exact steps right now). There's also a "root shell" option in
service mode boot, but that requires you to enter the root password
