Hello again,
The server is probably up but the ILO is not, is the AMS agent also installed? This agent relays OS info for the server on behalf of the ILO. Since you have servernames you probably have an AMS agent installed. Check if the ILO is configured to send traps to the SIM server, you need to configure this to get events. Also configure to send the OS name instead of the ILO name, this way events get mapped to the server instead of the ILO.
Good luck!
