Two possibilities spring to mind:
   - either the agent is not configured to allow access to these objects,
   - or the agent does not provide this information under AIX

You can check the first by seeing what else you can see under the 'ucd-snmp'
tree.   If the output of
         snmpwalk -v2c -c private hostname   ucdavis

is essentially empty when querying the AIX agent, then the first is the
most likely cause.   Check the access control settings in the agent.

If the output is broadly similar for both AIX and Linux agents, but with
individual chunks missing under AIX,  then it's more likely to be due to
the agent implementation code   (which is highly OS-specific)

Given that you've compiled the agent yourself, it's reasonably simple to
determine what modules are being used.
  Please list the contents of 'agent/mibgroup/ucd-snmp' and look at the
object files (.o/.lo).   I would expect to see either disk.o  *or*  disk_hw.o
Which is present?
   If it's disk_hw.o, then please list  'agent/mibgroup/hardware/fsys' as well.
Which .o files are present there?

It's essentially the same across all OS's.
The main difference is with what code is present, and hence which
MIB modules are implemented on particular OS's.   Given that AIX
is an environment that (AFAIK) none of the core developers have
access to,  this may well be one of the weaker systems.
