Hello there,
The proper way to discover your (blade) servers is first discover the OA, the XML reply that give the ILO information. So if this finishes you have you Enclosure, modules in the enclosure and blades. The OA and ILo only know the hardware bit. So now you have server with the name of the serialnumber. If you discover your servers OS with credentials and have the Hp Management agents running. If the system is cerectly discovered the system finds the serialnumber the system now knows the servers link the serial already present in SIM. Now the serial gets deleted and replaced with the server with discovered Status and System information.
If the server is not discovered correctly the server you discover gets the status unknown an the serialnumer server stays without any extra information.
Kind regards,
Andre
