Hello,
First install the Agentless Management Service, below is the link for a Windows 2012 R2 OS : http://h20564.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=5258668&swItemId=MTX_5130c84914c34c178d4a8a2f1c&swEnvOid=4168
When the software is installed you need to login to the ILO, go to the Administration > Management menu option. Enable the Agentless Management option, Set the Read comunity, Trap Community and SNMP Alert Destination in the SNMP Settings field and click the Apply button. Now in the same screen under the SNMP Alerts select the OS Hostname if you want your alerts to be linked to the server instead of the ILO.
Now if you also aplied this option you should identify your ILO, as you now have SNMP as a new protocol for the ILO a Datacollection will start for the ILo and should add extra driver and firmware info to the server in SIM.
