If you use the RHEL 6.5 inbox OpenFabrics Enterprise Distribution (OFED) package, the Remote Direct Memory Access (RDMA) in RHEL 6.5 might fail to run.
Affected software:
Sun Dual Port QDR InfiniBand Host Channel Adapter for PCIExpress Gen 3 (7104073 and 7104074)
Red Hat Enterprise Linux 6. 5
Workaround:
None.
Update the Mellanox OFED package. To download the update package, go to http://www.mellanox.com/page/products_dyn?product_family=26, scroll down the page and click the MLNX_OFED 2.X, and download MLNX_OFED_LINUX-2.1-1.0.0-rhel6.5x86_64.iso.
To install the Mellanox OFED update package, perform the following steps:
Mount the ISO image, and run the ./mlnxofedinstall --without-fw-update command. Note - You must use the --without-fw-update qualifier to prevent the installation from flashing the firmware on the Sun Dual Port QDR InfiniBand Host Channel Adapter for PCIExpress Gen 3 card; otherwise, the installation will fail.
Reinstall RDMA package from yum or from the RHEL 6.5 installation ISO. Modify the /etc/rdma/rdma.conf file to change RDS_LOAD=no to RDSLOAD=yes and save the file.
Start/restart the RDMA service.
