The Integrated Lights Out Manager (ILOM) Interconnect is an internal 10MB Ethernet-Over-USB interface between the ILOM and the server's Solaris host / primary LDom, which is used to communicate Fault Management Architecture (FMA) and other data. The Fault Management Architecture uses the Interconnect to proxy the faults diagnosed on the Service Processor (SP) to the Host, and to proxy the faults diagnosed on the Solaris Host to the SP. This is known as FMA Fault Proxying which keeps the FMA faults in sync between the host and the SP on T5-x or newer servers. When the FMA Fault Proxying mechanism does not work, FMA on SP and Solaris Host still works but the faults diagnosed are no longer proxied to the other side.
The following faults can occur for many different reasons, and some are related to the ILOM interconnect:
FMD-8000-D6 - alert.oracle.solaris.fmd.ip-transport.interconnect-down
ILOM-8000-EM - alert.ilom.fm.ip-transport.interconnect-down
FMD-8000-ET - alert.oracle.solaris.fmd.ip-transport.link-down
ILOM-8000-F7 - alert.ilom.fm.ip-transport.link-down
