IIRC, the address in question is 0xc2, and the from below the address of the local card is 0xc2. So if the SDR has the wrong address, it's not going to work.
And I was wrong, the driver does not detect that an IPMB message is to the local address and route it properly. So ipmitool will need to know. -corey Jan Safranek wrote: > On 02/04/2010 12:09 AM, Corey Minyard wrote: >> You can also change it in the IPMI driver and I believe that will work, >> too.
