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 tasks you must perform in conjunction with this procedure, to install the switch.

   See the table in Installation Sequence.

2. On the Linux InfiniBand host, type:

   # ibcheckerrors 
   #warn: counter SymbolErrors = 65532     (threshold 10) lid 85 port 255
   Error check on lid 85 (Sun DCS 648 shmm1500 LC slot 6 switch 1) port all:  FAILED 
   #warn: counter SymbolErrors = 65535     (threshold 10) lid 1 port 255
   Error check on lid 1 (Sun DCS 648 shmm1500 LC slot 6 switch 0) port all:  FAILED 
   .
   .
   .
   ## Summary: 55 nodes checked, 0 bad nodes found
   ##          1296 ports checked, 0 ports have errors beyond threshold
   #
