I've contacted SUN about this, a ticket is open... Today, I've found similar logs on another system "HP DL360 G6"... here are the logs... IPMI message handler: BMC returned incorrect response, expected netfn 5 cmd 27, got netfn 5 cmd 35 IPMI message handler: BMC returned incorrect response, expected netfn 5 cmd 27, got netfn 5 cmd 35 IPMI message handler: BMC returned incorrect response, expected netfn 5 cmd 27, got netfn 5 cmd 35 what I've done is : $ watch -n1 "ipmitool sensor" So this let me think that it's maybe not a bug in BMC...
