Configure network connections—SRP over Infiniband

If your configuration uses the SRP over Infiniband protocol, follow the steps in this section.

About this task

To connect the Linux host to the storage array, you must enable the InfiniBand driver stack with the appropriate options. Specific settings might vary between Linux distributions. Check the NetApp Interoperability Matrix Tool for specific instructions and additional recommended settings specific to your solution.

Steps

  1. Install the OFED/RDMA driver stack for your OS.
  2. Configure OFED/RDMA to load the SRP module.
  3. In the OFED/RDMA configuration file, set SRP_LOAD=yes and SRP_DAEMON_ENABLE=yes.
  4. Enable and start the OFED/RDMA service.
    For RHEL 7.x and SLES 12.x
    • To enable the InfiniBand modules to load on boot:
      systemctl enable rdma
    • To load the InfiniBand modules immediately:
      systemctl start rdma
    For RHEL 6.x and SLES 11.x
    • To enable the InfiniBand modules to load on boot:
      chkconfig rdma on
    • To load the InfiniBand modules immediately:
      service rdma start
  5. Enable the SRP daemon.
    For RHEL 7.x and SLES 12
    • To enable the SRP daemon to start on boot:
      systemctl enable srpd
    • To start the SRP daemon immediately:
      systemctl start srpd
    For RHEL 6.x and SLES 11.x
