Did you enable IPMI over Lan in the BMC/DRAC config?



The way I understand the documentation:

1. Access the DRAC web interface. (Only available through the DRAC NIC port.)
2. Telnet Console.  (Only available through the DRAC NIC port.)
3. RACADM. (Remote via -r through DRAC NIC, or locally.)
4. SSH Interface. (Same as Telnet, just encrypted.)
5. IPMI Interface - Provides access through the DRAC 5 to the remote system's basic management features. The interface includes IPMI over LAN, IPMI over Serial, and Serial over LAN. (Available trough server NIC.)


Conclusion:
 Through the server NIC you have IPMI capabilities only. To access DRAC only features you have to connect through the DRAC NIC.
