Checking the InfiniBand fabric
The IB Fabric Check allows you to clear and scan the InfiniBand fabric for errors. The
ib_fabric_check utility uses scripts provided with the OFED drivers to gather information about the InfiniBand fabric and clear the port counters. See “Utility commands” (page 51) for more details, including sample log files. The recommend usage is as follows:
1.Select the appropriate link speed and clear the fabric.
2.Run the initial scan of the fabric.
3.Run the tests and then scan the fabric again to check for InfiniBand fabric errors.
