Anyone can help me to find out problem or bug in my cluster? The output of "ibv_devinfo -v" from Dell blade with infiniband module look very strange. The phys_port_cnt is 2, one active, and another down. The active port is 20x speed, the down port is 10x speed. We are using Dell PowerEdge M600 Blade Serverwith Mellanox ConnectX DDR infiniband Mezzanine card and Cisco M2401G infiniband switch. OS is centOS 5.3, kernel 2.6.18-128.1.6el5 with PGI V7.2-5 compiler, and OFED-1.4.1-rc4 with openmpi-1.3.2:
