The RDMA communication might fail when using the RHEL 6.5 inbox OFED package (17933299)

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:

  1. 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.

  2. 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.

  3. Start/restart the RDMA service.


Note -  If you want to use "rds-tools" to manage or test RDMA performance, ensure that "rds-tools" is updated to a minimum version of 2.0.7.
