The reason is:
Jan 01 01:46:17 321555 [58F3E280] -> osm_vendor_set_sm: ERR 5431: setting
IS_SM capability mask failed; errno 2

>From the code it looks like  /dev/infiniband/issm<umad_port> needs to be
created and I did that. But still the SM with higher GUID seem to become the
master whenever it does a sweep. The logs are too detailed. So I am sending
snippets.
