In this case, it may be his only way in, if the v20z is the same Newisys box I worked with a while back (I think it is), his assessment that the Service processor is not accessible in-band may be accurate. Their IPMI support wasn't that great either at the time, but you could ssh into it and do things that way.. In any event, the BMC was so separate it could not reasonably know an in-band management attempt was being done.
It has been a long time and things may have changed since then, but the SP implementation of those boxes at the time had crappy, token IPMI support and were really intended to be used via ssh and the web interface (the service processor ran linux on a embedded power chip, it's "SOL" support was even a conserver install in the BMC flash to give you an idea of how different the service processor was from the more general stuff). I seem to recall IPMI could even be disabled (it was a linux proxy kinda thing to translate basic IPMI command set to native commands), if so that could be your deal. You should ask Sun about how to deal with the v20z. The question then is, does it work from another box aside from the one being managed? If not then this discussion can be moot.
