I believe it's OFED but I suppose I'm not certain. The initial installation of these systems included IB support which was installed by the vendor along with the OS (CentOS 5.5) and which was turned off ("chkconfig openibd off") when delivered. I don't seem to have an "ofed_info" command. Also, my openib.conf is in /etc/ofed rather than /etc/infiniband. It contains: [root at storage0 ~]# cat /etc/ofed/openib.conf # Load IPoIB IPOIB_LOAD=yes # Load SDP module SDP_LOAD=yes # Load the RDS protocol driver RDS_LOAD=yes # Load SRP module SRP_LOAD=yes # Load iSER module ISER_LOAD=yes # Should we modify the system mtrr registers? We may need to do this if you # get messages from the ib_ipath driver saying that it couldn't enable # write combining for the PIO buffs on the card. FIXUP_MTRR_REGS=no ..
