Corey (or anyone), do you have a tool which parses these logs and translates the unexpected netfn messages to a human readable representation like the "Get SDR" you show above? I can do it manually (or write a script), but don't want to duplicate effort if it already exists. > You should report this to Sun, though if everything else is working > correctly and it's not spewing out these errors it shouldn't affect > normal operations very much. We have seen cases where it spews, and others where it it's intermittent but when it happens it does mess up some IPMI- based monitoring. And I think some cases where it's just a sporadic complaint with no noticable consequences. I think at least some cases of this are due to SMM (System Management Mode -- special out of band CPU mode that gets underneath the host OS). An SMI (SMM interrupt) comes in, SMM BIOS code executes and either reads the response you were expecting or sends a new command to which you then read the response. If this is the case, BIOS authors have to fix it by eliminating the IPMI access; using a different channel or interface; or ensuring that they never issue a command while a response is pending and always consume the response after issuing a command (not sure if that last method is actually viable). >Bela< ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
