        CA type: MT26428
        Number of ports: 1
        Firmware version: 2.6.0

        Node GUID: 0x0008f1476328oaf0

It is due to the Subnet Manager (opensm) not being installed. Voltaire OFED Installation package installed only the OpenIB Packages. Even if you have install the opensm before installing the Voltaire OFED Package, the Voltaire OFED Package will uninstall the existing opensm packages to ensure openib packages are fully compatible.

To install the Opensm packages nicely, do read on the blog entry Installing Voltaire QDR Infiniband Drivers for CentOS 5.4
