On other hand, freeipmi (as a set of IPMI client tools) relies only on a service processor feature (and only on a service processor that supports IPMI 1.5/2.0, and not ELOM, ILOM etc.).
Freeipmi CAN monitor local machine, if local machine HAS service processor feature. In current state, freeipmi is not able to notify FMA but if that would be needed, it could be done (s new feature). If local machines does NOT have service processor supporting IPMI, then freeipmi can NOT notify FMA. I think that there is NO overlap between freeipmi and FMA - first, freeipmi does not automatically switch monitoring services on, and even if it is switched on, it has to be defined what actions has to be performed under which circumstances. > > Most importantly: is there any negative impact on FMA? > I do not understand the question - if you configure the freeipmi in a way, that it watches remote machine and performs shutdown when CPU temperature reaches 60oC while FMA is configured in a way (I do not know if it is possible, just guessing) that it has to switch off the machine when CPU temperature reaches 60oC and freeipmi is faster then FMA (so it reboots the machine sooner, then FMA is able to perform shutdown), then YES, it can have negative impact. But in such sense, anything can have negative impact on FMA - for me, it is the administrator's responsibility to configure the machine in a way that it works reliable. It is important, that by default (after installation) freeimpi does NOTHING. it has to be configured to DO something. > But also, FMA and SMF both seem to allow for the possibility of a > networked future in that FMRIs are practically URIs.
