The ibcheckerrors command uses the topology file to scan the InfiniBand fabric and validate the connectivity as described in the topology file, and to report errors as indicated by the port counters.
Note - The output for your InfiniBand fabric will differ from that in the example.
# ibcheckerrors ## Summary: 4 nodes checked, 0 bad nodes found ## 34 ports checked, 0 ports have errors beyond threshold #
Note - The thresholds are dependent of time since the last reset. If you see a lot of errors, reset the counters with the ibclearerrors command. Check the errors a few minutes later with the ibcheckerrors command.
