OME 1.2.1 can't see all devices

Good morning all,

I've installed OME 1.2.1 to monitor 4 esx 5 servers (PowerEdge r720) i use SNMP,ICMP protocol, i was able to discover the servers via the IDRAC and i can see them on 'irac window' i also was able to forward all snmp alerts to a scom server, all work fine, but i can't see/inventory of all other devices like network devices, power device, storage devices of discovered servers.

Can you please help understand what's going wrong with my config?

Thanks in advance.

Salento.
