We updated from OFED 22.214.171.124 to Mellanox OFED 2.1 (everything on CentOS 6.3 64bit). The installation went smooth, but now ipconfig ib0 shows the same MAC (different from before) on all nodes:
HWaddr A0:00:01:00:FE:80:00:00:00:00:00:00:00:00:00:00:00:00:00:00. This leads to problems.
I don’t even know what to look for. The firmware still seems to have the correct values for the MAC:
mstflint -d 01:00.0 q

MACs: 0002c9184420 0002c9184421
How can we fix that?
