[Lustre-discuss] Luster 1.8.3 Qlogic OFED 1.4.2

[Kevin Van Maren]

With OFED, you use o2ib.  iib was for the old InfiniCon/SilverStorm 
InfiniServ IB software (pre-OFED) that QLogic acquired (as opposed to 
the InfiniPath software they acquired from PathScale).

With an stock OFED install it is "--with-o2ib=/usr/src/ofa_kernel", but 
the path may be different for the qlogic version.
