Validate the InfiniBand Fabric and Report Errors

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.

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:

   # ibcheckerrors 
   #warn: counter RcvSwRelayErrors = 48342         (threshold 100) lid 25 port 255
   Error check on lid 25 (Sun DCS 72 QDR FC switch o4nm2-72p-2) port all:  FAILED 
   #warn: counter RcvSwRelayErrors = 56839         (threshold 100) lid 25 port 28
   Error check on lid 25 (Sun DCS 72 QDR FC switch o4nm2-72p-2) port 28:  FAILED 
   #warn: counter RcvSwRelayErrors = 56839         (threshold 100) lid 25 port 9
   Error check on lid 25 (Sun DCS 72 QDR FC switch o4nm2-72p-2) port 9:  FAILED 
   #warn: counter SymbolErrors = 65535     (threshold 10) lid 20 port 255
   Error check on lid 20 (Sun DCS 72 QDR switch 1.2(LC)) port all:  FAILED 
   .
   .
   .
   ## Summary: 6 nodes checked, 0 bad nodes found
   ##          144 ports checked, 2 ports have errors beyond threshold
   #

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