Perform Diagnostics on the InfiniBand Fabric

The ibdiagnet command performs a collection of tests on the InfiniBand fabric and generates several files that contain parameters and aspects of the InfiniBand fabric.

  1. Identify the prerequisite and subsequent installation tasks that you must perform in conjunction with this procedure.

    See Installation Sequence.

  2. On the management controller, type:

    # ibdiagnet

    In the following example, the ibdiagnet command is minimized to determine which links are underperforming:

    # ibdiagnet -lw 4x -ls 10 -skip all
    Loading IBDIAGNET from: /usr/lib/ibdiagnet1.2
    -W- Topology file is not specified.
         Reports regarding cluster links will use direct routes.
    Loading IBDM from: /usr/lib/ibdm1.2
    -I- Using port 0 as the local port.
    -I- Discovering ... 6 nodes (6 Switches & 0 CA-s) discovered.
    .
    .
    .
    -I- Links With links width != 4x (as set by -lw option)
    -I---------------------------------------------------
    -I- No unmatched Links (with width != 4x) were found
    -I---------------------------------------------------
    -I- Links With links speed != 10 (as set by -ls option)
    -I---------------------------------------------------
    -I- No unmatched Links (with speed != 10) were found
    .
    .
    .
    -I- Stages Status Report:
         STAGE                                    Errors Warnings
         Bad GUIDs/LIDs Check                     0      0 
         Link State Active Check                  0      0 
         Performance Counters Report              0      0 
         Specific Link Width Check                0      0 
         Specific Link Speed Check                0      2 
         Partitions Check                         0      0 
         IPoIB Subnets Check                      0      0 
    Please see /tmp/ibdiagnet.log for complete log
    ----------------------------------------------------------------
    -I- Done. Run time was 16 seconds.

    Note - The output for your InfiniBand fabric will differ from that in the example.


  3. Validate and check errors for the InfiniBand fabric.

    See Validate the InfiniBand Fabric and Report Errors.
