By default, the iLO's SNMP is set to passthrough, which requires you to 
run HP's SNMP agents on the host to collect data.  You won't get any data 
via SNMP on iLO unless they are running.

However, a new feature in iLO 4 is agentless management.  This means iLO 
can pull data from the sensors, hp raid arrays, etc directly, and you can 
poll iLO via SNMP without involving the OS at all.  You'll have to disable 
passthrough and enable agentless management via the web interface or 
hponcfg.  For the latter, I believe this will do the job:

   <LOGIN USER_LOGIN="Administrator" PASSWORD="password">
     <RIB_INFO mode="write"><MOD_SNMP_IM_SETTINGS>
       <SNMP_ADDRESS_1 VALUE=""/>

Unfortunately, this only works on iLO 4, so you'll still have to run 
HP's SNMP agents on your ilO 3 hosts if you want to collect host data via
