Hello,
What is the hardware type ? If it's a Gen8 or hogher you need to install the Agentless Managmenet Agent. This software can be found here : http://h20564.www2.hpe.com/hpsc/swd/public/detail?sp4ts.oid=5177951&swItemId=MTX_05d34f4a9cc84230ada3590ea8&swEnvOid=4168
For this to work corectly you also need to configure SNMP on the ILO. If your server is a Gen 7 or earlier you need to install the WBEM agent, the SNMP agent is the older agent and the WBEM is preferred. The WBEM agent can be found here :
You would also need a System Management Homepage on the older servers, this can be found here :
Hope this helps for you. If you need more info on configuring let me know.
