disk broke on ibm server

Hi,
I installed sim 6.3 for manage HP server. In my network I have also some IBM server (X3650, X3400 and DS3400 storage).
When I discover IBM server I read in system type "unknown" and read green box only for HS field.
How I must discover IBM server and storage. I will use sim main for detect disk broke, power supply broke and memory broke. On the IBM server I configured (as on hp server) comunity and snmp settings on snmp services.

Thanks

Jonh
