No process is required to run w/ port 623 since rmcpping communicates with the service processor on a motherboard. If the service processor runs on stand-by power (many motherboards do, yours may not necessarily) that means you can even rmcpping a machine when it is powered off. > In that case how is the communication b/w BMC and MCs is done?? > Is it through the IPMB Bus?? i.e., does BMC and MCs on the blades > never use Ethernet to communicate (Specifically MCs not the processes like > openhpiapps running on blades)?? I've seen some bladed solutions that only allow remote management with the blade manager, and not with an individual blade. It is the responsibility of the blade manager to then communicate with each blade to do the management activity (power control, sensor retrieval, etc.). I don't know your specific hardware, so I can't really say about your particular hardware. I *think* communication is done through the ICMB bus to the blades, but my terminology understanding may be wrong here. However, I've also seen it done through serial. So it's just up to the implementation.
