Determine host port GUIDs.

Determine host port GUIDs and make the recommended settings

The infiniband-diags package includes commands to display the globally unique ID (GUID) of each InfiniBand (IB) port. Most Linux distributions with OFED/RDMA supported through the included packages also have the infiniband-diags package, which includes commands to display information about the the host channel adapter (HCA).

Steps

  1. Install the infiniband-diags package using the operating system’s package management commands.

  2. Run the ibstat command to display the port information.

  3. Record the initiator’s GUIDs on the SRP worksheet.

  4. Select the appropriate settings in the HBA utility.

    Appropriate settings for your configuration are listed in the Notes column of the NetApp Interoperability Matrix Tool.
