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.

Procedure

  1. Install the OFED/RDMA driver stack for your OS.
    SLES
    zypper install rdma-core
    RHEL
    yum install rdma-core
    
  2. Configure OFED/RDMA to load the SRP module.
    SLES
    zypper install srp_daemon
    RHEL
     yum install srp_daemon
  3. In the OFED/RDMA configuration file, set SRP_LOAD=yes and SRP_DAEMON_ENABLE=yes.
    The RDMA configuration file is located at the following location:
    /etc/rdma/rdma.conf
  4. Enable and start the OFED/RDMA service.
    RHEL 7.x and SLES 12.x or greater
    • To enable the InfiniBand modules to load on boot:
      systemctl enable rdma
    • To load the InfiniBand modules immediately:
      systemctl start rdma
  5. Enable the SRP daemon.
    RHEL 7.x and SLES 12 or greater
    • To enable the SRP daemon to start on boot:
