Hello there,
Are your systems (servers)of type Gen8 or higher ? When only export de ILO's.
If you have enclosures export the Onboard administrators. If you like you can select management processors, this will select both. If you have older systems like G7 and older then you need to create a collection for all servers that are not of Type Gen, this will show all older systems than Gen8. Do you know how to create collections ?
